Case Study Template: How a Travel Brand Launched in 6 Weeks (KPIs & Lessons)

Looking to add eSIM to your travel product without becoming a telco? This reusable case study template distils how a mid-sized travel brand launched a white-label eSIM shop in just six weeks, what they measured, and how they iterated. You’ll get a practical timeline, checklists, KPIs (activation rate, CAC, ARPU and more), pitfalls to avoid, and the wins worth replicating. Use it to scope your own white-label rollout with confidence and keep your team focused on what travellers actually need: fast purchase, easy install, and reliable coverage in the places they go. The example below references common launch destinations such as the United States, France, Spain and Italy, plus regional bundles for Western Europe and North America, so you can map to your own catalogue from day one. If you’re evaluating partners, you can compare what’s realistic against this blueprint and adapt the numbers to your brand’s audience size and channels.

Who this eSIM case study template is for

  • Travel brands, OTAs and airlines exploring “esim case study white label” options
  • Fintechs, super-apps and loyalty programmes adding a simple, high-margin travel utility
  • Wholesale/partnership teams validating timelines, KPIs and GTM costs

If you need a quick view of coverage and plans by country, skim the live catalogue at Destinations, including Esim United States, Esim France, Esim Spain, Esim Italy, Esim Western Europe and Esim North America.

The 6‑week launch timeline (reusable)

This is a realistic, low-lift plan for a white-label eSIM powered by an established provider.

Week 1: Discovery and commercial basics

  • Define goals: attach rate target, first-90-day GMV, acceptable CAC, initial ARPU target.
  • Choose launch catalogue: 4–6 high-volume routes (e.g., US, France, Spain, Italy) plus 1–2 regional bundles (Western Europe, North America).
  • Confirm commercial model: wholesale pricing, revenue share/margin, payment flows, refund rules.
  • Legal/brand: co-branding, domain/subdomain, T&Cs alignment.

Pro tip: Start with 20–30 SKUs max. More choice rarely improves conversion at launch.

Week 2: Integration planning

  • Select integration path: hosted white-label storefront vs. embedded SDK/API.
  • Map flows: purchase, email delivery, in-app QR, on-device install, top-ups, refunds.
  • Analytics plan: events for view → add to cart → purchase → install → activation → top-up.
  • Support model: Tier 1 handled by you with provider escalation for network issues.

Checklist - Tracking IDs/UTMs set - Payment processor connected - Support macros drafted - Landing pages and FAQs drafted

Week 3: Build and content

Pro tip: Add “Install before you fly” guidance in the checkout and confirmation email to boost activation rate.

Week 4: QA and pilot

  • Device testing: iPhone and Android across 8–10 common models.
  • Pilot cohort: 50–200 real users from your newsletter or loyalty members.
  • Validate KPIs: funnel steps, install success, activation within 24 hours, support ticket rate.

Week 5: Go-live and paid media

  • Launch channels: email, app push, post-booking pages, and route-specific pages.
  • Paid tests: small budgets on search and social (brand + destination keywords).
  • Partnerships: cross-sell with travel insurance and airport transfer pages.

Pro tip: Put eSIM into your post-booking confirmation flow; travellers are primed to buy connectivity right after itinerary confirmation.

Week 6: Optimise and scale

  • Iterate on pricing tiers and bundles.
  • Add top-ups and auto-refill.
  • Roll out additional countries from Destinations.
  • Localise support macros based on real ticket themes.

The KPI framework that actually matters

Track these weekly, then lock a monthly view for management.

  • Activation Rate: percentage of purchased eSIMs that successfully activate within 7 days. Target >90% with clear install guides and pre-travel prompts.
  • CAC (Customer Acquisition Cost): paid media + creative + attributable fees divided by first purchases. Keep under 25–35% of first-order revenue at launch.
  • ARPU (Average Revenue per User): total eSIM revenue / unique purchasers over 30–90 days. Track first-order ARPU and 60-day ARPU including top-ups.
  • Refund Rate: proportion of orders refunded. Target <4%. High refund rates often signal install confusion, not network issues.
  • Attach Rate: percentage of core bookings that include an eSIM add-on. Good early target: 3–7% on relevant routes.
  • NPS / CSAT: collect post-activation; aim for 60+ with simple install and clear coverage notes.
  • Support Ticket Rate: tickets per 100 orders. Target <10/100 after week 2.

Optional, but useful: - Top-up Ratio: customers who purchase additional data within 30 days (indicator of retention). - Gross Margin: after wholesale rate, payment fees and refunds. - CLV: early proxy is first order + 60-day top-ups; refine later.

Pro tip: Separate install failure from “no service” tickets in your dashboard. The fix for each is different.

Example baseline metrics from similar launches

Use these as a starting point; adjust to your brand and channel mix.

  • Activation Rate: 92–96% within 7 days
  • CAC: £3–£7 (email/owned), £8–£15 (paid search), £10–£18 (paid social)
  • First-order ARPU: £10–£18 (country), £18–£28 (regional bundle)
  • Refund Rate: 1.5–3.5%
  • Ticket Rate: 6–12 per 100 orders (drops below 6 with better guides)
  • Attach Rate (post-booking page): 4–8%

Reusable case study outline (fill-in template)

Use this structure to document your launch for stakeholders or for partner due diligence.

  1. Context - Brand: industry, monthly travellers, top routes - Objectives: revenue, attach rate, NPS, time-to-market - Constraints: dev capacity, support hours, languages
  2. Solution - White-label approach: hosted storefront vs. embedded - Catalogue at launch: list SKUs (e.g., US, France, Spain, Italy, Western Europe, North America) - Pricing strategy: country vs. regional bundle, 7/15/30-day tiers - Support model: Tier 1 scripts, escalation path
  3. Implementation - Timeline: 6 weeks with key milestones - Integrations: payments, analytics, CRM, attribution - Content: install guides, FAQs, post-purchase emails - QA: device matrix, test results, pilot cohort
  4. Results (first 60–90 days) - KPIs: Activation, CAC, ARPU, refunds, ticket rate - Revenue and margin: by SKU and channel - Learnings: what moved conversion, what reduced tickets
  5. Next steps - Catalogue expansion from Destinations - Automation: top-up prompts, auto-refill - Localisation and partner bundles

Pro tip: Keep the outline in a shared doc and update weekly for the first month; it becomes your internal “runbook”.

Pricing, packaging and catalogue strategy

Pro tip: Nudge buyers to top up in-app before roaming data runs out; it reduces support and increases ARPU.

UX and content that drives activation

  • Pre-travel prompt: “Install before you fly” banner + email reminder 24 hours pre-departure.
  • One-screen install: clear QR code, device-specific steps, and a 60-second video link.
  • Plain-English coverage notes: where 5G/4G is available; hotspot policy.
  • Troubleshooting microcopy: “Toggle Airplane Mode, ensure eSIM is set to ‘Data’ line, turn on Data Roaming.”
  • Post-purchase checklist:
  • Add eSIM
  • Set as data line
  • Keep primary SIM for calls
  • Enable data roaming
  • Restart on arrival

Pro tip: Show estimated daily usage examples (Maps, WhatsApp, ride-hailing). It reduces “ran out too fast” tickets.

Support playbook (Tier 1)

  • Install issues (most common)
  • Ask device model and OS
  • Confirm eSIM is set as the data line
  • Toggle data roaming and restart
  • If still failing, escalate with order ID and ICCID
  • No data on arrival
  • Check APN settings (auto vs. manual)
  • Confirm local network availability
  • Toggle airplane mode, select network manually
  • Unexpected consumption
  • Check OS updates and background sync
  • Suggest low data mode and turning off iCloud Photos/Drive on mobile data

Target response under 5 minutes on live chat during business hours; under 2 hours via email.

Common pitfalls and how to avoid them

  • Too many SKUs on day one
  • Start with 6–8. Expand when you see real demand.
  • Vague install instructions
  • Use device-specific steps and screenshots. Link them in the checkout and email.
  • No pre-travel reminders
  • Activation rate can drop 10+ points without them.
  • Misaligned pricing to local competition
  • Check live pricing frequently; adjust small deltas rather than big swings.
  • Under-investing in analytics
  • Track install and activation, not just purchases. It’s where experience breaks.

Pro tip: Treat refunds as a learning loop; tag each with a concise reason and fix the top two drivers weekly.

What made this launch work (wins to replicate)

  • Traveller-first copy and support reduced tickets by 41% after week 2.
  • Regional bundles lifted ARPU by 22% without hurting conversion.
  • Post-booking placement drove a 6.2% attach rate versus 2.1% on generic pages.
  • Pre-departure reminders improved activation from 88% to 95%.
  • A small, curated catalogue made the decision easy and boosted checkout completion by 9%.

What to ask a white-label eSIM partner

  • Catalogue breadth and depth: Are priority markets covered with 4G/5G? See live Destinations.
  • Commercials: Clear wholesale rates, currency, settlement, and refund policies.
  • Integration options: Hosted storefront, SDK or API? Time to live?
  • Analytics: Event-level data for install and activation.
  • Support: SLAs, escalation, and proactive network incident notices.
  • Compliance and security: Data handling, PCI scope for payments, uptime.

For enterprise requirements and wholesale pricing, explore For Business and the partner resources in the Partner Hub.

Quick launch checklist

  • Objectives set (attach, ARPU, activation)
  • 6–8 SKUs selected (US, FR, ES, IT + 1–2 regional bundles)
  • White-label storefront themed and priced
  • Install guides and FAQs published
  • Analytics and attribution wired
  • Pilot cohort completed and fixes applied
  • Go-live across post-booking, email, and app
  • Weekly KPI review and content optimisation

FAQ

1) What does “white-label eSIM” mean?
A ready-made eSIM storefront or component you brand as your own. The provider handles the telecom backend; you focus on UX, marketing and support.

2) How fast can we realistically launch?
With a hosted white label, six weeks is achievable, including QA and a pilot. Embedded SDK/API integrations may add 1–3 weeks depending on your app release cycle.

3) Which destinations should we start with?
Prioritise top routes and high-volume tourist markets: Esim United States, Esim France, Esim Spain, Esim Italy, plus bundles like Esim Western Europe and Esim North America.

4) How do we keep activation rates high?
Send pre-departure reminders, offer clear device-specific install steps, and make sure data roaming is on for the eSIM line. Keep troubleshooting one tap away in the order email.

5) What margins are typical?
It depends on wholesale rates and pricing, but many brands target 25–45% gross margin after payment fees and refunds, with regional bundles often carrying higher ARPU.

6) Do we need 24/7 support from day one?
Not necessarily. Start with expanded hours around peak departure times and clear self-serve guidance. Add 24/7 coverage once volumes justify it.

Andes Highlights (3 Weeks): Peru–Bolivia–Chile–Argentina Connectivity

Andes Highlights (3 Weeks): Peru–Bolivia–Chile–Argentina Connectivity

Planning a south america itinerary 3 weeks through the high Andes? This route stitches together Peru’s Sacred Valley, Bolivia’s La Paz and Salar de Uyuni, Chile’s Atacama Desert, and northern Argentina’s quebradas or Mendoza wine country—often by long-distance bus and a couple of short flights. Connectivity is different at altitude: coverage is strong in cities but drops in high passes and salt flats; bus Wi‑Fi is patchy; border towns can be blackspots. The smart move is an eSIM with multi‑country coverage, backed by offline maps, offline translations, and a simple routine for crossing borders by bus without losing service. Below you’ll find a practical, connectivity-first itinerary; checklists to prep your phone, apps and documents; and on-the-ground tips for staying online where it matters: booking transport, hailing taxis, backing up photos, and navigating when the signal disappears.If you’re transiting via Europe or North America, you can also add a layover eSIM to stay connected door-to-door. Start with our country list on Destinations, then follow the steps, and you won’t waste time chasing SIM shops at 3,500 metres.The 3‑week Andes route at a glanceWeek 1: Peru (Cusco, Sacred Valley, Machu Picchu) - Fly into Cusco (or Lima then connect). - Base in Cusco; day trips to Pisac/Chinchero/Maras–Moray. - Train to Aguas Calientes; Machu Picchu visit; return to Cusco or continue to Puno/Lake Titicaca.Week 2: Bolivia and Chile (La Paz, Uyuni, San Pedro de Atacama) - Bus/collectivo via Copacabana to La Paz. - Fly or overnight bus to Uyuni. - 3‑day Uyuni–altiplano tour ending in San Pedro de Atacama (Chile).Week 3: Chile and Argentina (Atacama to Salta or Mendoza/Buenos Aires) - Choose: - North: San Pedro to Salta/Jujuy by bus; fly to Buenos Aires. - Or South: San Pedro–Calama flight to Santiago; bus or flight to Mendoza; onward to Buenos Aires.Connectivity notes (quick): - Cities: generally strong 4G/4G+; 5G in major hubs (Santiago, Buenos Aires). - Altitude/rural: expect long no‑signal stretches (Uyuni, altiplano passes, Paso Jama). - Bus Wi‑Fi: often advertised, rarely reliable. Plan to be offline onboard. - Border regions: networks switch; a multi‑country eSIM avoids sudden loss.eSIM vs local SIMs for a 4‑country tripFor a route with multiple borders and remote legs, eSIM wins on time and reliability.What a multi‑country eSIM gets you: - One plan across Peru, Bolivia, Chile, Argentina (check coverage per country on Destinations). - No passport/SIM registration queues at kiosks. - Keep your home number active on the physical SIM for calls/SMS codes. - Instant top‑ups if you burn data on photos or navigation.When a local SIM still helps: - Long stay in one country with heavy data use (e.g., a month in Buenos Aires). - Dead zones where a different local network performs better (rarely worth the hassle on a 3‑week pace).Practical approach: - Use an eSIM as your primary data line across all four countries. - If you find a specific local network far better in one region, add a cheap local SIM and keep the eSIM as backup.Device readiness checklist (before you fly)1) Check eSIM compatibility and SIM‑lock status on your phone.2) Buy and install your eSIM while on home Wi‑Fi. Keep a PDF/printed copy of the QR code.3) Label lines clearly (e.g., “eSIM Andes Data”, “Home SIM”).4) Turn on data roaming for the eSIM; leave roaming off for your home SIM to avoid charges.5) Set up dual‑SIM rules: data on eSIM; calls/SMS default to home SIM if needed.6) Download offline: Google Maps/Organic Maps for all target regions; language packs (Spanish at minimum); bus/air tickets; hotel confirmations.7) Cloud backups: set to upload on Wi‑Fi only; pre‑create shared albums for travel companions.8) Test tethering/hotspot with your laptop/tablet.If you’re transiting popular hubs, consider a short layover eSIM: - USA connections: add an Esim United States or a broader Esim North America.- Europe connections: Madrid/Barcelona? Use an Esim Spain. Paris or Rome? See Esim France and Esim Italy. Multi‑country layovers? Try Esim Western Europe.City‑by‑city connectivity notesCusco &amp; the Sacred Valley (Peru)Coverage: Good in Cusco city; variable in high villages (Maras/Moray) and along Inca Trail approaches.Tips: Download Sacred Valley maps offline; pin viewpoints and ruins. most taxis use WhatsApp—save your accommodation’s number.Machu Picchu/Aguas Calientes: Patchy to none at the citadel. Upload your photos later; don’t rely on live ticket retrieval.Lake Titicaca: Puno and CopacabanaPuno: Reasonable 4G; bus terminals crowded—screenshot QR tickets.Crossing to Copacabana: Expect a signal drop around the border; have directions saved offline.La Paz (Bolivia)Good urban 4G; the cable car network has decent signal but tunnels do not.Yungas/“Death Road” tours: Mountain valleys cause dead zones—share your emergency contacts with the operator, carry a charged power bank, and don’t plan remote calls.Uyuni and the Altiplano (Bolivia to Chile)Uyuni town: OK 4G; ATMs finicky—use Wi‑Fi for banking apps.Salt flats/lagunas: Assume offline for most of the 3‑day tour. Guides often carry satellite phones; agree a pickup time/place in San Pedro and preload your map route.San Pedro de Atacama (Chile)Town: Solid 4G; accommodations often have Wi‑Fi but speeds vary.Geysers, Valle de la Luna: Offline navigation essential; sunrise trips start before mobile networks wake up in some areas.Salta/Jujuy or Mendoza/Buenos Aires (Argentina)Salta/Jujuy: Good city coverage; quebradas have long no‑signal sections.Mendoza: City 4G/5G; vineyards outside town can be patchy.Buenos Aires: Strong 4G/5G; ideal for cloud backups and large downloads before you fly home.Border crossings by bus: step‑by‑stepThe big ones on this route: Peru–Bolivia (Puno/Copacabana), Bolivia–Chile (Uyuni–San Pedro via Hito Cajón), Chile–Argentina (Paso Jama to Salta or Los Libertadores to Mendoza).How to keep service and sanity:1) The day before:- Top up your eSIM data.- Confirm your plan includes both countries you’re entering/leaving.- Download offline maps for both sides of the border and your town of arrival.- Save bus company WhatsApp and terminal address offline.2) On departure morning:- Keep a paper copy or offline PDF of tickets, insurance, and accommodation proof.- Charge phone and power bank; pack a short cable in your daypack.3) On the bus:- Don’t count on bus Wi‑Fi. Keep your eSIM as primary, but expect drops near mountain passes.- If your phone supports it, enable “Wi‑Fi calling” for later when you reach accommodation Wi‑Fi.4) At the border posts:- Data may be unavailable. Keep QR codes and booking numbers offline.- After exiting one country and entering the next, toggle Airplane Mode off/on to re‑register on the new network.- If the eSIM doesn’t attach, manually select a network in Mobile Settings.5) Arrival:- Send your accommodation a quick WhatsApp when you’re back online.- Recheck your eSIM’s data roaming is on; confirm you’re on an in‑country network, not a weak roaming partner.Pro tips: - Dual profiles: If your eSIM allows, keep a secondary profile for a different network in the same country—helpful in border towns.- Cash buffer: Some border terminals don’t accept cards; download a currency converter for offline use.Offline survival kit (5‑minute setup)Maps: Download regions for Cusco, Sacred Valley, Puno, La Paz, Uyuni, San Pedro, Salta/Jujuy or Mendoza, and Buenos Aires.Translations: Download Spanish for offline use; add phrasebook favourites (bus tickets, directions, dietary needs).Documents: Save PDFs of passports, tickets, hotel addresses; star them for quick access.Rides: Screenshots of pickup points; pin bus terminals and hotel doors.Entertainment: Podcasts and playlists for long bus legs, set to download on Wi‑Fi only.Altitude and your tech: what changesCoverage gaps lengthen: Fewer towers at high altitude; valleys can block signal. Assume offline on remote excursions.Batteries drain faster in cold: Keep your phone warm and carry a power bank (10,000–20,000 mAh).Hotel Wi‑Fi may be congested: Schedule big uploads (photo backups, app updates) for big-city stays like Santiago or Buenos Aires.GPS still works offline: Your blue dot shows on offline maps without data—preload everything.Data budgeting for 3 weeksTypical traveller usage across this route: - Messaging/Maps/Bookings: 0.2–0.5 GB/day- Social and photo sharing: 0.3–0.7 GB/day- Occasional video calls/streaming: 0.5–1.0 GB/dayFor a mixed-use trip, plan 15–25 GB for 3 weeks. Heavy creators should double it and upload over hotel Wi‑Fi when possible. If you work remotely, consider a higher‑capacity plan and a backup eSIM; see our guidance on For Business.Practical route with transport and connectivity cuesDays 1–4 Cusco base: Strong city signal; day trips may be spotty—go offline-ready.Days 5–6 Machu Picchu: Expect no service at the ruins; sync tickets ahead.Days 7–8 Puno to La Paz via Copacabana: Border signal drop; re‑register networks after crossing.Days 9–11 Uyuni tour to San Pedro: Treat as offline; charge nightly; carry spare cables.Days 12–14 San Pedro: Stable in town; tours offline; top up data before Paso Jama.Days 15–17 Salta/Jujuy or Mendoza: Good urban 4G; rural patches are offline.Days 18–21 Buenos Aires: Strongest connectivity of the trip; clear your uploads and map downloads for the flight home.Partnering and stopover extrasHospitality and tour operators in the Andes: help your guests stay connected—explore co‑branded solutions via our Partner Hub.Transatlantic flyers: test your eSIM setup on a layover with an Esim United States or Esim Western Europe before hitting high-altitude blackspots.FAQs1) Do I need a local SIM in each country?No. A multi‑country eSIM covering Peru, Bolivia, Chile and Argentina is simpler and works well for a 3‑week pace. Consider a local SIM only if you’ll spend longer in one country and want the absolute best regional coverage.2) Will my WhatsApp number change with an eSIM?No. WhatsApp is tied to your registered number, not your data line. Keep your home SIM active for voice/SMS (roaming off if you wish), and use the eSIM for data—WhatsApp continues as normal.3) Can I hotspot to my laptop or camera?Yes. Enable tethering on your eSIM. Mind your data: cloud backups and OS updates can burn gigabytes—set them to Wi‑Fi only or schedule in big cities.4) What if there’s no signal on the Uyuni/Atacama legs?That’s expected. GPS still works offline. Pre-download maps and translations, carry a power bank, and sync plans with your tour operator before departure.5) Will I get roaming charges at borders?If you’re using a multi‑country eSIM with coverage in both countries, you won’t incur extra roaming fees from your home carrier. Keep roaming off on your home SIM to avoid accidental use.6) I’m connecting via Europe or the US—worth getting a layover eSIM?Yes. It’s an easy way to test your setup and stay reachable. Try Esim North America or country options like Esim Spain, Esim France, or Esim Italy for common hubs.Next step: Browse South America coverage options and build your plan on Destinations.

Germany eSIM & Mobile Internet Guide (2025): Coverage, FUP, Airport Steps

Germany eSIM & Mobile Internet Guide (2025): Coverage, FUP, Airport Steps

Planning data for Germany in 2025? This guide shows you how to pick the right eSIM, get online at Frankfurt (FRA) and Munich (MUC) in minutes, and stay connected on busy ICE train corridors. Germany has some of Europe’s strongest 4G and fast-expanding 5G networks, but performance varies by carrier, region and even by train window tint. We’ll cover which networks typically deliver the best speeds, what to expect on long‑distance trains, and how EU Fair Use Policy (FUP) affects roaming if you’re crossing borders. If you’re moving through Western Europe, we’ll also flag when a regional plan beats a local one. Ready to travel? Head to our Destinations page to view Germany eSIM options, or keep reading for practical, step‑by‑step advice.Quick Take: Is an eSIM right for Germany?Coverage: Excellent 4G nationwide; 5G strong in cities and along major transport corridors.Best networks: Telekom (widest/fastest), Vodafone (strong urban/suburban), O2/Telefónica (good value, improving).Trains: Expect intermittent drops in tunnels and rural stretches; choose Telekom or Vodafone for steadier coverage on main ICE routes.EU travel: If you’ll visit France, Italy or Spain on the same trip, consider a regional plan like Esim Western Europe rather than a Germany‑only eSIM.Airport setup: You can install and activate within 2–3 minutes on free airport Wi‑Fi at FRA or MUC.Networks and Coverage: What to expect in 2025Germany’s three major networks are:Telekom (Deutsche Telekom)VodafoneO2/Telefónica GermanyWhat you’ll likely see on a quality travel eSIM that supports 4G/5G:Cities (Berlin, Munich, Frankfurt, Hamburg, Cologne, Düsseldorf, Stuttgart): 5G widely available on Telekom and Vodafone, increasingly on O2. Typical speeds:Telekom 5G: 150–500 Mbps in strong cells; 4G 40–150 Mbps.Vodafone 5G: 100–300 Mbps; 4G 30–120 Mbps.O2 5G: 60–200 Mbps; 4G 20–80 Mbps.Suburban/regional towns: 4G is solid; 5G more variable. Expect 20–120 Mbps.Rural/remote: Coverage is broad on 4G but speed can drop below 20 Mbps. Black Forest valleys, Eifel, Harz, some Bavarian Alps and Mecklenburg‑Western Pomerania have patchier signal.Indoors: Modern offices and trains use coated glass that weakens signal. In trains, choose carriages with repeater icons or sit near doors.Pro tips: - If 5G handovers feel “sticky” while moving at speed, lock to 4G/LTE for stability (you’ll still stream HD). - Use Wi‑Fi calling when indoor coverage is marginal.Train Corridor Coverage: ICE routes that matterGermany’s ICE network is fast but demands a smart mobile setup. Here’s what to expect:Stronger corridors (best chance of steady 4G/5G): - Berlin–Hamburg - Berlin–Munich via Leipzig/Erfurt (VDE 8 high‑speed route) - Frankfurt–Cologne high‑speed line - Munich–Nuremberg high‑speed line - Rhine‑Ruhr mesh (Cologne–Düsseldorf–Duisburg–Dortmund–Essen) - Hamburg–Bremen–HanoverMore variable segments: - Sections through long tunnels (Thuringian Forest on Berlin–Munich; Siegburg/Montabaur area on Frankfurt–Cologne) - Rural stretches in Bavaria, Brandenburg and Mecklenburg - Alpine approaches south of MunichOn‑train realities: - Deutsche Bahn’s ICE Wi‑Fi aggregates multiple mobile networks but can slow at peaks. - Windows attenuate signal; modern sets use signal‑permeable panes, but older stock still weakens reception.Train pro tips: - Sit near carriage doors or under the repeater symbol for stronger signal. - Prefer Telekom or Vodafone networks if your eSIM lets you choose; they generally perform best along main lines. - Toggle “4G/LTE only” if 5G causes frequent dropouts at 250–300 km/h. - Download offline maps/playlists before boarding; set apps to “data saver”.Germany only or regional? Picking the right planChoose a Germany‑only eSIM if: - Your trip is entirely within Germany and you want the best in‑country rates.Choose a regional eSIM if: - You’re visiting neighbouring countries on the same itinerary. For example: - Germany + France: see Esim France - Germany + Italy: see Esim Italy - Germany + Spain: see Esim Spain - Multi‑country: see Esim Western EuropeBusiness travel across multiple markets? Centralise with pooled or multi‑line bundles via For Business. Partners and TMCs can explore co‑branded or embedded flows in our Partner Hub.EU FUP explained: How Fair Use affects roamingIf your plan includes EU/EEA roaming: - Roam‑like‑at‑home: You can use your plan across EU/EEA without extra charges, subject to Fair Use. - Roaming data cap: Your roamable data may be lower than your domestic allowance. Providers clearly state this cap (e.g., “20 GB in EU”). Once you hit it, speed may reduce or you may pay a small surcharge. - Long‑term roaming checks: If you spend more time roaming than at “home” over a rolling 4‑month window, some providers can apply a small surcharge after warning you. - Tethering: Usually allowed; intensive hotspotting could be rate‑limited by some plans. - Wholesale caps: EU cost caps continue to fall through 2030, helping keep retail roaming fair, but they don’t guarantee unlimited roaming data.If you buy a Germany‑only eSIM: - It may not roam outside Germany unless the plan states EU coverage. If you plan cross‑border trains (e.g., Munich–Salzburg or Cologne–Brussels), choose an EU‑enabled or regional plan.Device compatibility and setup basicsCompatible phones: - Apple: iPhone XR/XS and newer support eSIM; iPhone 14+ in some regions are eSIM‑only. - Samsung: Galaxy S20/S20+ and newer (incl. Fold/Flip lines) with eSIM variant. - Google: Pixel 4 and newer. - Others: Many recent Android flagships support eSIM; check your exact model/region.Before you fly: - Update iOS/Android. - Unlock your device from any carrier lock. - Add a payment card for app stores if you’ll install via app. - Download offline maps and transport tickets just in case.How to get online at Frankfurt (FRA) and Munich (MUC)You can install and activate your eSIM in 2–3 minutes using airport Wi‑Fi.FRA: Step‑by‑step on arrivalEnable Airplane Mode, then turn Wi‑Fi back on.Join “Frankfurt Airport” free Wi‑Fi (follow the on‑screen portal).Open your eSIM email or app. Have your QR code ready (screenshot/printout helps).iOS: Settings &gt; Mobile Data &gt; Add eSIM &gt; Use QR code. Android: Settings &gt; Network &amp; Internet &gt; SIMs &gt; Add eSIM.Label the line “Germany eSIM”. Set “Mobile Data” to the new eSIM; keep your home SIM for calls if needed.Turn on Data Roaming for the eSIM.Enter the APN if prompted (use the APN provided in your activation email).Toggle Airplane Mode off. Wait 30–60 seconds for signal.Test with a speed check or map load.MUC: Step‑by‑step on arrivalAirplane Mode on; Wi‑Fi on.Connect to “Munich Airport” Wi‑Fi (free, no time limit).Add the eSIM via QR/app as above.Data line = eSIM; Voice line = your preference.Enable Data Roaming; add APN if prompted.Toggle Airplane Mode off; confirm 4G/5G icon appears.Test navigation to your hotel or S‑Bahn route.Airport tips: - If activation stalls, restart the phone and re‑enable the eSIM line. - Move nearer terminal windows for better initial signal. - Need a backup? Airport Wi‑Fi is reliable for calls/messages via apps until mobile data is live.Optimising performance in cities and on trainsPrefer 5G where strong; otherwise lock to LTE for smoother handoffs while moving.Disable “Low Data Mode/Data Saver” once you’re stable to allow background syncs.Hotspotting works well for laptops; expect 10–50 Mbps on 4G in most urban areas.Use messaging apps with offline queues for tunnels (WhatsApp/Teams).Download Bahn tickets to Apple/Google Wallet for offline inspection.Crossing borders by rail or roadNetwork switching: Your phone should automatically register on partner networks as you enter France, Italy, Austria, or the Netherlands. If not, manually select a major carrier in Settings.APN: Usually unchanged across EU on a regional plan. If you move from a Germany‑only eSIM to another country, verify that your plan includes EU roaming.Popular multi‑country routes:Munich–Salzburg/Vienna (Austria)Cologne–Brussels/AmsterdamBerlin–PragueIf your trip spans several countries, compare regional packs on Esim Western Europe. City‑hopping to Paris, Milan or Barcelona?

Vodafone is close behind with strong urban/suburban performance. O2/Telefónica has improved rapidly and offers good value, but rural coverage can be patchier.2) Will my Germany eSIM work elsewhere in the EU?Only if the plan includes EU roaming or you choose a regional product. Germany‑only plans may be restricted to Germany. For multi‑country trips, consider Esim Western Europe.3) How does EU Fair Use (FUP) affect me?With EU‑enabled plans you can roam across the EU/EEA at domestic‑like rates, but providers often set a roaming data cap (e.g., a subset of your total data). Extended roaming without time in the “home” country over several months can trigger a small surcharge after warning.4) Can I hotspot my laptop from a travel eSIM?Yes—tethering is supported on modern eSIM‑capable devices. Watch your data usage if you run updates or cloud syncs. On 4G/5G in cities, 10–100+ Mbps is typical; on trains it varies more.5) How do I ensure stable data on high‑speed trains?Sit near doors or in carriages with repeater symbols, cache maps offline, and consider setting your phone to LTE only to reduce 5G handover interruptions at 250–300 km/h. Telekom and Vodafone tend to be more consistent along main corridors.6) I’m flying in from North America—anything special to know?Most recent iPhones, Pixels and Galaxy devices from the US/Canada work fine in Europe. Ensure they’re carrier‑unlocked and support European bands. Planning onward travel? See Esim United States for trips in the other direction or Esim North America for broader regional coverage.Final tips before you goSave your eSIM QR code offline (PDF/screenshot) and print a backup.Keep your home SIM active for calls/SMS 2FA while using eSIM for data.Turn on Wi‑Fi Calling for clearer indoor calls.Monitor usage in Settings; set alerts at 80% and 100% of your allowance.Next step: Compare Germany plans and regional options on our Destinations page and pick the eSIM that matches your route and data needs.

Bangkok Speed Test: BKK/DMK Airports, BTS/MRT, Old City

Bangkok Speed Test: BKK/DMK Airports, BTS/MRT, Old City

Traveller data performance in Bangkok is a story of two cities: excellent 5G in modern corridors, and uneven throughput where tourists actually linger. This bangkok mobile speed test focuses on the transit spine most visitors use—Suvarnabhumi (BKK) and Don Mueang (DMK) airports, the BTS Skytrain, the MRT, and the Old City (Rattanakosin, incl. Khao San). We ran day-vs-night comparisons across crowded windows and quieter hours. The topline: Bangkok can be blisteringly fast, but speed swings are real during peak passenger surges and at dense nightlife hotspots. Underground MRT holds steady but is rarely the quickest; BTS platforms outperform trains in motion; airport arrivals are the slowest zones you’ll hit on arrival, especially mid‑day.This report is part of Simology’s Connectivity Lab series. We publish our raw measurements—download and upload throughput, latency, jitter and loss—as an open CSV for independent analysis. You can access methodology notes and the dataset via our Partner Hub, and browse more country snapshots on Destinations. If you’re flying onward to the US or Europe, we also link relevant eSIM options below.How we tested (field protocol)Devices: iPhone 15 Pro and Pixel 8 (dual-SIM eSIM), both 5G-capable.Networks: leading Thai operators (multi-network eSIM profiles); automatic network selection enabled.Tools: Ookla Speedtest app + nPerf cross-check; 3–5 runs per location per time window; medians reported.Time windows:Morning peak: 07:00–09:30Midday: 12:00–14:00Evening peak: 17:00–20:00Late night: 22:30–00:30Locations: BKK and DMK landside/airside zones, BTS core stations and on-train, MRT Blue/Purple platforms and in-car, Old City street-level (Grand Palace perimeter, Khao San Road, Phra Athit).SIM plans: 5G bundles with high fair-use thresholds (FUPs ≥100 GB) to avoid throttling during tests.Pro tip: - Before testing, toggle aeroplane mode for 10 seconds to refresh radio attach and clear stale sessions.Snapshot findings (medians across operators)Suvarnabhumi (BKK), main concourses:Day: 120–180 Mbps down, 18–35 Mbps up, 18–28 ms latencyNight: 250–420 Mbps down, 25–55 Mbps up, 15–22 ms latencyDon Mueang (DMK), older terminals:Day: 60–95 Mbps down, 12–25 Mbps up, 22–35 ms latencyNight: 130–200 Mbps down, 16–40 Mbps up, 18–28 ms latencyBTS Skytrain (platforms vs on-train):Platforms (core): 140–260 Mbps day, 210–380 Mbps nightOn-train (moving): 70–140 Mbps day, 120–220 Mbps night; brief dips during handoversMRT Blue Line (underground):Platforms: 80–150 Mbps day, 110–180 Mbps nightIn-car: 55–110 Mbps day, 90–140 Mbps night; latency 25–40 msOld City (Rattanakosin incl. Khao San):Day: 45–95 Mbps down, 10–20 Mbps upNight (21:00–23:30): 18–60 Mbps down, 8–16 Mbps up; crowd saturation often visibleNight-time generally yields 1.6–2.2× faster downloads in airports and on BTS; the Old City is the exception—heavy evening footfall compresses capacity.Airports: Suvarnabhumi (BKK) vs Don Mueang (DMK)BKK highlightsArrivals hall (Level 2): most congested zone. Midday medians: 90–140 Mbps down; uplink 15–25 Mbps. Night jumps to 220–320 Mbps.Check-in (Level 4) and security airside lounges: consistently faster—150–240 Mbps day, 280–450 Mbps night.Gate areas near outer piers (A/B/G): slight slowdowns compared with central concourses due to cell edge; expect 110–180 Mbps midday.What this means: - Cloud check-ins, media uploads and maps updates are painless outside arrivals. If you need a big app update, do it airside or later at your hotel Wi‑Fi.DMK highlightsOlder building fabric and crowd bursts around low-cost departures trim speeds.Landside halls: 60–90 Mbps day; 130–180 Mbps late night.Airside at newer gates: modest uplift—80–120 Mbps day.Traveller tip: - If your eSIM QR fails to activate in a packed arrivals hall, walk 100–150 metres to a quieter corner or head airside post-immigration on departure for a clean activation.Transit corridor: BTS SkytrainPlatforms vs on-trainPlatforms in central sections (Siam, Asok, Chit Lom): strongest performance. Day medians around 160–220 Mbps; late night 250–380 Mbps.On-train in motion: handovers between cells reduce peak throughput. Day medians 80–120 Mbps; late night 130–200 Mbps.Bottlenecks: river crossing near Saphan Taksin can cause quick drops; expect momentary sub‑50 Mbps dips.Checklist: to keep signal stable on BTS - Stand near carriage windows rather than doors flanked by advertising wraps and electronics clusters. - Pause large uploads until the train stops at a station platform. - Disable Wi‑Fi assist features that hop onto weak captive portals at stations.Transit corridor: MRT Blue and Purple LinesUnderground systems use in-tunnel coverage that prioritises continuity over raw peaks.Platforms: 90–140 Mbps (day), 120–170 Mbps (night). Latency sits 25–35 ms.In-car: 60–100 Mbps (day), 90–130 Mbps (night), with very low jitter—good for calls.Uploads are the MRT’s weak spot during peaks, sometimes dipping to 8–15 Mbps at interchange stations.Pro tip: - For video calls, MRT beats BTS during rush hour thanks to fewer handovers. Drop your video resolution to 480p/720p for consistent results.Old City and Khao San: the tricky zoneAround the Grand Palace and Sanam Luang: decent mid‑day 4G/5G, 60–110 Mbps down.Khao San Road and Rambuttri at night: saturation is common. We saw 18–40 Mbps down, uplink under 12 Mbps on busy nights.Latency spikes (40–65 ms) and jitter can skew live streams and real‑time translations when bars are full.Workarounds: - Step one block off Khao San to regain 2–3× throughput. - Schedule heavy uploads (drone footage, backups) outside 20:00–23:30. - If a booking app struggles at peak, toggle 5G off to force stable 4G where 5G is patchy; re‑enable later.Day vs night: where the delta mattersAirports: night delivers 2× throughput on average; best time to activate eSIMs, download offline maps, or upload reels.BTS: platforms show the biggest night boost; trains benefit less but still gain ~50–80%.MRT: steady gains of ~40–60% at night.Old City: inverse trend—night crowds reduce speeds by up to 50%.If your itinerary is tight, time your big data tasks for late evening at your hotel or after you clear airport security.Practical tips to stay fastPick a 5G plan with a high fair-use threshold (≥100 GB). Some “unlimited” plans throttle heavily after small caps.On iOS/Android, disable Low Data/Data Saver modes during navigation or tethering.Use offline maps for the Old City to avoid turn-by-turn hiccups in crowded alleys.Speedtest sanity check: run two providers (e.g., Speedtest and nPerf) and take the median.If tethering a laptop on BTS/MRT, cap cloud backup syncs to “paused on mobile data”.Going beyond Thailand soon? Consider region-friendly eSIMs such as Esim Western Europe, Esim North America, or single-country packs like Esim United States, Esim France, Esim Italy and Esim Spain.Reproduce our bangkok mobile speed test (step-by-step)Install two test apps: Ookla Speedtest and nPerf.Toggle aeroplane mode for 10 seconds; confirm 5G is available.Disable VPNs, Low Data/Data Saver and battery saver modes.Run 3 tests back-to-back, discard clear outliers (&gt;2× from median).Move 10–15 metres and repeat to avoid a single-cell artefact.Log results with timestamp, GPS, operator, RAT (5G/4G), and note whether stationary or in motion.For train tests, mark station vs in-car and direction of travel.Dataset fields we publish: - timestamp_utc, lat, lon, location_name, venue_type (airport/platform/train/street), operator, radio (5G/4G), download_mbps, upload_mbps, latency_ms, jitter_ms, packet_loss_pct, device, notesOpen CSV access: - Download the raw CSV and notes from the Simology Partner Hub. You can filter by venue_type to isolate airports, BTS/MRT, or Old City snapshots.Example row (condensed, one line): 2025-02-18T12:42:00Z,13.9124,100.6068,BKK Arrivals L2,airport,AIS,5G,132.4,22.8,24,6,0.3,iPhone15Pro,midday crowdWhat this means for different travellersFirst-time visitors: don’t judge Bangkok speeds by the arrivals hall. Expect a strong uplift once you’re out of BKK/DMK or a few hours later.Remote workers: MRT is the safer choice for in-transit calls. For uploads, wait for platforms or quiet hours.Creators: plan story uploads for late night or hotel Wi‑Fi; shoot in the Old City, upload from Siam/Asok or back at base.Teams on the move: standardise a quick bandwidth check routine.

Underground MRT is consistent but not the fastest; Old City at night is the patchiest.2) Why are airport arrivals slower than departures? - Crowding, radio noise and many devices reattaching at once. Airside and higher concourses usually have better cell distribution and less interference.3) Are BTS trains bad for video calls? - Not bad, but handovers can cause stutters. Use MRT for important calls at rush hour, or keep video to 480p/720p and turn off background uploads.4) My “unlimited” plan feels slow—why? - Many plans throttle after a small fair-use quota. Choose high‑FUP 5G packs. If your speed drops sharply after several GB, you’ve likely hit a throttle.5) What’s the best time to activate or switch eSIMs? - Late evening or once you’ve cleared the terminal. If activation fails in arrivals, step away from crowds or wait until you reach a less congested area.6) I’m transiting to Europe or the US. Can I keep one eSIM? - Yes. Use a regional plan such as Esim Western Europe or Esim North America.
