App Update (vX.Y): eSIM Compatibility Checker 2.0 + APN Finder

Travellers want one thing from mobile connectivity: it should just work. This simology app update focuses on removing the guesswork. In vX.Y, we’re introducing eSIM Compatibility Checker 2.0 and a new APN Finder to make sure your phone is genuinely eSIM-ready for your destination, and your data comes up first time. The upgraded checker runs a deeper device scan (on-device, privacy-first) to assess eSIM support, 4G/5G and VoLTE readiness, dual SIM limitations, and region quirks. The APN Finder pairs your device and destination with the correct Access Point Name settings and can apply them automatically on many Android devices. iPhone users get clear, per-carrier instructions.

You’ll also find faster QR installs, clearer status messages, and more help built in. Where relevant, we’ve added labelled screenshots in the app’s Help and on the store listing to guide you through each step. If you’re heading to multiple countries, our regional guides—like Esim Western Europe and Esim North America—work hand-in-hand with this update for a smoother trip.

How eSIM Compatibility Checker 2.0 works

The new checker verifies more than “does my phone support eSIM?” It also looks at what will work where you’re going.

Step-by-step: run the checker

  1. Open the simology app and tap Compatibility Checker.
  2. Allow the app to read device and network capabilities (no personal data collected).
  3. Select your destination(s) or pick a regional bundle like Esim Western Europe or Esim North America.
  4. Tap Run Check.
  5. Review the results screen, which includes: - eSIM support status (hardware + OS) - 4G/5G capability and likely regional band fit - VoLTE readiness (important in countries phasing out 3G) - Dual SIM nuances (e.g., 5G may be limited to one SIM) - Recommended next steps and a link to suitable plans

Understanding your result

  • Good to go
  • Your device supports eSIM, the destination’s bands, and VoLTE/5G where applicable.
  • Proceed to purchase and install. Expect immediate data after activation.
  • Works with caveats
  • Examples: 5G not guaranteed in rural areas; VoLTE required on certain carriers; dual SIM may restrict 5G to one line.
  • We’ll show clear notes and the best plan fit.
  • Not supported
  • Your device or OS doesn’t support eSIM, or regional compatibility is too limited.
  • We’ll suggest alternatives or upgrades.

Pro tips: - Update your OS first. eSIM features often improve with the latest iOS/Android build. - If you run dual SIM, keep your primary line set to “Calls/SMS only” to prioritise data on the travel eSIM. - For multi-country trips, re-run the check for each country to catch band differences (e.g., 5G n78 in parts of Europe vs n71/n41 in North America).

APN Finder: get data working first time

APN (Access Point Name) settings tell your phone how to connect to a carrier’s data network. Many eSIMs auto-configure APNs; some don’t. APN Finder removes the guesswork.

Step-by-step: apply APN with one tap (Android)

  1. In the simology app, go to APN Finder.
  2. Choose your destination and selected plan/carrier.
  3. Tap Apply APN.
  4. Confirm the change when prompted.
  5. Toggle Airplane mode off/on once; data should come up within 30 seconds.

Note: Auto-apply works on most stock Android and recent Samsung/Pixel devices. If your OEM skin blocks APN edits (seen on some carrier-locked models), the app will guide you to manual entry.

Step-by-step: guided APN on iPhone

  1. Open APN Finder in the app and select your destination.
  2. Tap View Settings to see the exact fields.
  3. On your iPhone, go to Settings > Mobile Data > your eSIM > Mobile Data Network.
  4. Enter the APN, Username, and Password exactly as shown (other fields can stay blank unless specified).
  5. Return to the main screen and toggle Mobile Data off/on.

If you don’t see “Mobile Data Network,” your carrier profile may manage APNs automatically; give it a minute after activation or reboot your device.

Manual APN fallback (quick checklist)

  • Turn off Wi‑Fi while testing mobile data.
  • Ensure Mobile Data and Data Roaming are enabled for the eSIM line.
  • Reset network settings only if needed (this clears saved Wi‑Fi/Bluetooth).
  • As a final step, remove and re-add the eSIM profile if activation stalled.

Planning a trip? Match plan to device and region

Use the checker to align your device with the right plan. Some examples:

  • United States: 3G shutdowns make VoLTE essential. Check your device’s VoLTE readiness and see our Esim United States guide for carrier options and 5G notes.
  • France, Italy, Spain: Many urban areas have strong n78 5G. Rural coverage can be 4G-focused. Compare notes in Esim France, Esim Italy, and Esim Spain.
  • Multi-country Europe: If you’ll cross borders, consider Esim Western Europe to avoid APN resets at every border.
  • USA + Canada + Mexico: See regional options in Esim North America and run the checker for each country to confirm 5G band fit.

Shortcut: Browse all supported locations in Destinations, then use the checker to validate your device before you buy.

Known issues and current workarounds

We test widely, but some OEM and OS behaviours vary. Here’s what we’re tracking:

  • iOS manual APN visibility
  • Some carriers lock APN fields on iPhone. If APN fields are missing, wait 2–3 minutes after activation or reboot; the profile often autoloads. If not, our guide will confirm whether manual entry is supported.
  • Samsung dual SIM + 5G priority
  • On certain models, 5G works on only one SIM at a time. Set your travel eSIM as the “Primary SIM for mobile data” in SIM Manager. Toggle Airplane mode after switching.
  • MIUI/ColorOS APN edit restrictions
  • A few builds restrict APN editing. Our APN Finder will show a manual path if available. If not, use the auto-config QR from the plan screen or contact support via in‑app Help & Feedback.
  • Pixel VoLTE toggle location
  • On some Pixels, VoLTE/4G Calling toggles are under Network & Internet > SIMs > Preferred network type. Ensure VoLTE is on in the destination country.
  • Older Android versions (pre-11)
  • eSIM management can be less stable. We recommend upgrading if possible before travel for smoother activation.

We’ll keep this list updated as OEM updates roll out. Most hiccups are resolved by toggling Airplane mode, switching the data SIM to your travel eSIM, or re-applying APN settings.

For teams and partners

Managing multiple travellers?

  • For travel managers: bulk activation guidance, device readiness reports, and invoicing are available in For Business.
  • For distributors and affiliates: access co-branded resources, plan catalogues, and onboarding via the Partner Hub.

The checker can be used during device onboarding to pre-qualify travellers before they depart.

Privacy and data handling

  • On-device first: device capability checks run locally.

  • Optional diagnostics: if you opt in while seeking support, we collect anonymised device model/OS/build and error codes to improve the tool. You can opt out any time.

How to share feedback

We build from real travel scenarios. To help us prioritise:

  • In the app: Settings > Help & Feedback > Send feedback (attach logs if you consent).
  • Feature requests: tag “APN Finder” or “Compatibility Checker” to route it quickly.
  • Partners: submit requests via the Partner Hub.

We review feedback weekly and publish release notes with fixes and improvements.

FAQ

  • Will the checker guarantee 5G in every city?
    No tool can guarantee 5G everywhere. The checker validates your device’s capability and the region’s typical bands. Coverage depends on local towers and your location (e.g., indoor vs outdoor). We’ll always show when 5G is unlikely so you can set expectations.
  • Do I need to run the checker for each country on a multi-stop trip?
    Yes. Bands and VoLTE policies differ by country. Run it per stop, or select a regional plan like Esim Western Europe or Esim North America and review the per-country notes.
  • Can the APN Finder change my iPhone settings automatically?
    iOS typically requires manual APN entry unless the carrier profile auto-loads. The app provides exact values and a short checklist. On many Android devices, we can apply APNs with one tap.
  • What if my device says “Not supported” but other sites claim it’s eSIM-ready?
    Some models have regional variants. Our check looks at your exact hardware/firmware, which may differ from the general spec sheet. If you believe it’s an error, send feedback with your model number; we’ll verify.
  • Does the app use mobile data during checks?
    Checks run locally and are lightweight. If you’re fully offline, you’ll still get device-capability results; regional hints and APN lists use a cached snapshot when available.
  • Will this update help with voice and SMS?
    The checker flags VoLTE readiness (critical for voice where 3G is retired). SMS behaviour depends on the plan and local network. Data connectivity remains our primary focus.

Next step

Plan your route, then validate your device before you buy. Start with our full list of supported locations in Destinations, run the Compatibility Checker for each stop, and use APN Finder to bring data up on arrival.

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 & 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.

Offline areas reduce this to near-zero aside from search and traffic updates.Is “unlimited” data worth it while travelling?Often not. Many “unlimited” plans have fair-use thresholds and speed caps. A well-sized 20–40 GB plan is enough for most 2–3 week trips, with better speeds and price per GB. Go unlimited only if you stream a lot or tether daily.Do WhatsApp and iMessage use much data?Texts and stickers are tiny (a few MB/hour). Voice calls use ~0.5 MB/min; video calls 5–10 MB/min. Daily messaging plus a short video call can still fit in 300–500 MB/day.Should I buy one regional plan or separate country plans?If you’ll cross borders, regional plans like Esim Western Europe or Esim North America are simpler and often cheaper than juggling multiple country eSIMs. Single-country trips may be best served by local plans such as Esim France, Esim Italy or Esim Spain.Can I use my eSIM for hotspot/tethering?Usually yes, but it can burn data quickly. A light work hour via hotspot can use 200–500 MB; HD video calls or updates can push 1–2 GB/hour. Check plan details for any tethering restrictions.What happens if I run out of data mid-trip?Most plans allow top-ups or add-ons. Set a daily warning, and if you’re trending over budget, lower streaming quality and delay large uploads to Wi‑Fi before you buy extra data.Next stepStart with your destination, pick your trip length, and choose a plan that matches your profile.

Wholesale Pricing & Forecasting: Volume Tiers, Commitments, and Margins

Wholesale Pricing & Forecasting: Volume Tiers, Commitments, and Margins

Wholesale pricing for eSIM is different to retail: you’re negotiating capacity, not just buying SKUs. That means tiers, commits, and forecasting accuracy decide your margin as much as your selling price. In this guide we unpack the mechanics of wholesale pricing eSIM: how tier schedules actually calculate, what “hard vs soft” commitments mean in practice, and how to build a forecast tied to travel seasonality and itineraries data. You’ll find worked breakeven maths, practical demand-shaping tactics that don’t hurt the traveller experience, and checklists you can run every month. We’ll also show where regional packs such as Esim Western Europe or Esim North America help you reach volume tiers faster—while still giving travellers the coverage they expect across popular routes like the US, France, Italy and Spain. If you’re a reseller, OTA, fintech, or device brand building travel connectivity, use this as your operating playbook.What drives wholesale pricing for eSIM?Wholesale price per GB (or per bundle) is set by a few levers:Volume tiers: lower unit costs kick in above stated thresholds (e.g., 10k, 50k, 100k GB/quarter).Commitments: price discounts in exchange for a minimum draw (soft commit) or pay-or-take (hard commit).Geography and roaming policy: single-country vs regional vs global; in-country vs roaming partners.Validity and pack size: shorter validity and micro-packs cost more per GB; larger bundles cost less.Quality-of-service: 4G/5G access, throttling thresholds, and fair-use policies.Commercial terms: price hold periods, FX currency, payment terms, and promotion allowances.Pro tip: - Aggregate demand into broader regional products (e.g., Esim Western Europe) to climb tiers faster without sacrificing the traveller experience.Tier schedules that actually workA tier schedule defines your unit cost as volume increases within a time window (usually monthly or quarterly). There are two common models:1) Stair-step (all units at the tier rate once you pass the threshold)2) Marginal (each tier’s rate applies only to the units within that tier band)Sample stair-step schedule (quarterly, illustrative USD):Tier 1: 0–9,999 GB = $4.50/GBTier 2: 10,000–49,999 GB = $3.90/GBTier 3: 50,000–99,999 GB = $3.30/GBTier 4: 100,000+ GB = $2.80/GBBlended cost calculation example (stair-step): - If you end the quarter at 12,000 GB, all 12,000 GB price at $3.90 → Blended = $3.90/GB. - At 9,800 GB you’re stuck at $4.50/GB. Missing the 10k tier by 200 GB costs: 9,800 × ($4.50 − $3.90) = $5880.Marginal schedule example: - First 10,000 GB at $4.50, next 40,000 GB at $3.90, etc. - Blended = (10,000 × $4.50 + 2,000 × $3.90) / 12,000 = $4.40/GB.Pro tips: - Ask which model applies; your demand-shaping tactics differ materially between stair-step and marginal. - Request a end-of-period “true-up” option if you’re near a threshold; it reduces expensive shortfalls.Commitments: soft vs hard (and why it matters)Commitments exchange predictability for price. The fine print decides your risk.Soft commit (drawdown): You commit to a volume window (e.g., 30 TB/quarter). If you fall short, you may roll forward a portion or pay a gap fee.Hard commit (take-or-pay): You pay for the committed volume whether you consume it or not, usually for deeper discounts.Floors/ceilings: Some contracts allow ±10–20% variance without penalty.Price protection: The wholesale rate is held for a fixed term; important in volatile FX or roaming markets.Carryover and expiry: Clarify if unconsumed volume can roll to the next period.Worked example (quarterly): - Commit: 30,000 GB at $3.60/GB (hard). Retail ASP blended = $5.40/GB. - If you consume 27,000 GB, you still pay for 30,000 GB. Effective cost per consumed GB = (30,000 × $3.60)/27,000 = $4.00/GB (margin shrinks). - If you hit 35,000 GB and a “best-tier-applies” clause exists, you may benefit from the 50k band if the schedule is marginal and pro-rata true-up is allowed.Checklist before you sign: - Commitment type and tolerance band - Tier model (stair-step vs marginal), and true-up mechanics - Price hold duration and currencies accepted - Carryover rules and expiry dates - Penalties, promo allowances, and support SLAsForecasting that matches travel seasonalityTravellers don’t move in straight lines; your forecast shouldn’t either. Anchor your plan to itineraries and known peaks.Key inputs: - Bookings and search data by corridor (origin–destination) - Seasonality curves (e.g., Europe peaks Jun–Sep; US peaks around spring break and summer) - Product mix by destination: Esim United States, Esim France, Esim Italy, Esim Spain, and regional packs like Esim Western Europe or Esim North America - Attach rate assumptions by channel (web, app, checkout upsell)Step-by-step: from itineraries to SKU forecast1) Map corridors and destinations- Use your booking data and reference coverage in Destinations to build a top-20 route list.2) Build monthly arrival curves- Distribute expected travellers by month using last year’s arrivals and events calendars (festivals, trade shows, school holidays).3) Set attach rate per corridor- Example: OTA checkout upsell 8–12%, post-booking emails 3–5%, in-app for existing users 15–25%.4) Choose pack mix by stay length and use- City-breakers: 3–5GB; road-trippers: 10–20GB; remote workers: 20–50GB regional packs.5) Convert travellers to data volume- Travellers × attach rate × average GB per plan = monthly GB demand.6) Layer variance buffers- Apply ±15% range, then choose a commit that your p50–p60 scenario can reliably hit.Pro tips: - Bundle single-country with regional coverage to capture multi-country itineraries (e.g., France–Italy–Spain) under one plan and push volume into a single tier. - Use early-bird promotions to pull demand from month 1 to month 0 when you’re close to a tier.Breakeven and margin maths made simpleKeep a small set of formulas in your pricing sheet:Blended wholesale cost per GB = Weighted average of tiers and/or commits.Revenue per GB (implied) = Average selling price (ASP) per plan ÷ Average consumed GB per plan.Gross margin % = (Revenue − Cost) ÷ Revenue.Worked example (USD, illustrative): - You sell a 10GB US plan at $18 ASP. Average actual consumption = 7.5GB (some users underuse). - Implied revenue per GB = $18 / 7.5 = $2.40/GB. - If your blended wholesale cost is $1.85/GB, gross margin = ($2.40 − $1.85) / $2.40 = 22.9%.Breakeven ASP targeting: - Target ASP = Blended cost per GB × Expected consumption per plan ÷ (1 − Margin target) - With $1.85/GB cost, 7.5GB consumption, 25% margin: Target ASP = 1.85 × 7.5 ÷ 0.75 = $18.50.Pro tips: - Monitor “consumption/entitlement ratio” (used GB ÷ plan GB). Improving utilisation by 0.5GB can lift margin more than a 20c price change. - FX hedging: if you buy in EUR and sell in USD/GBP, set an FX buffer in costs.Demand shaping that respects travellersThe goal: reach better tiers without compromising experience.Tactics that work: - Regional-first catalogues: Promote Esim Western Europe to travellers visiting France–Italy–Spain; promote Esim North America for US–Canada–Mexico trips. - Plan-size rationalisation: Offer 5GB/10GB/20GB core sizes; prune slow-moving variants that fragment volume. - Time-bound promos: Run 5–10% discounts late in the month/quarter if you’re within 5–8% of the next tier. - Value add-ons: Free hotspot allowance or extended validity instead of deep price cuts; protects ASP. - Tie-in at booking: Highlight coverage on destination pages like Esim France or Esim Italy within itineraries flows.Guardrails: - Keep throttling and fair-use transparent; never silently degrade service to squeeze margin. - Cap promo frequency to avoid training customers to wait for discounts.Risk management: variance and buffersEven great forecasts miss. Design controls:Safety commit: Contract at 60–70% of p50 demand; use spot or overage for spikes.Spillover product: If a country SKU risks overage, route customers to a regional SKU with headroom.Threshold alerts: Daily run-rate vs tier threshold; auto-trigger promotional levers when gap <8%.SLA monitoring: Latency and attach success; quality issues can tank conversion and strand volume.Scenario planning checklistRun this monthly in the run-up to peak season:Update arrivals and attach-rate assumptions by corridorRefresh tier attainment model and true-up statusRecalculate blended cost and breakeven ASPIdentify SKUs to promote for tier climbingValidate inventory/commit headroom by regionConfirm FX impact on costs and planned pricesPrepare switchbacks (alternative SKUs) if a network degradesCase example: Western Europe summer peakContext: - You expect 42,000 travellers across France–Italy–Spain June–August. - Attach rate target: 12% via checkout plus 4% in-app = 16% overall. - Average plan: 10GB regional.Forecast: - Travellers × attach rate = 6720 plans. - Entitlement volume = 6720 × 10GB = 67,200 GB. Expected consumption ratio 0.75 → 50,400 GB used.Commercial move: - Instead of three separate country SKUs, concentrate on Esim Western Europe to consolidate volume and achieve the 50k GB tier. - Offer a June pre-departure promo to pull 5% of July demand forward if you’re short of the threshold. - Feature destination coverage pages in your content stack: Esim France, Esim Italy, Esim Spain.Outcome: - Blended wholesale rate improves by $0.40/GB at the higher tier, translating to ~$20k extra gross margin over the quarter without raising retail prices.Operational mechanics and KPIs to trackInstrument these weekly:Activation success rate and time-to-first-byteAverage consumed GB per plan and consumption/entitlement ratioTop-ups per 100 activationsOverage and throttling incidenceRefund rate and support contact rateTier attainment tracker (run-rate vs thresholds)Channel attach rate trends (checkout vs post-booking vs in-app)Pro tip: - Tie a real-time “tier gap” widget into your merchandising engine to auto-boost regional SKUs when you’re near thresholds.How Simology helps partners executeCoverage and planning: Use Destinations to align catalogue with where travellers actually go, from the Esim United States to multi-country options like Esim North America.Commercial tooling: Consolidate commits across country and regional SKUs, with clear stair-step vs marginal models and end-period true-up options where available.Data and dashboards: Forecasting modules that ingest itineraries and seasonality; alerts for tier thresholds and SLA anomalies.Partner enablement: Bulk provisioning, voucher flows, and flexible APIs via the Partner Hub.B2B support: Contracting, FX-aware pricing guidance, and joint promotional planning—see For Business.FAQ1) What is “wholesale pricing eSIM” in plain terms?It’s the rate you pay for eSIM data capacity at scale, influenced by volume tiers and commitments, not just per-plan retail price. Your margin depends on hitting thresholds and managing consumption.2) Should I choose soft or hard commitments?If your demand is seasonal or volatile, soft commits with limited carryover reduce risk. If your forecast is dependable and you can aggregate demand (e.g., regional SKUs), hard commits can unlock better rates.3) How do I avoid missing a tier by a small margin?Monitor run-rate daily. In the final week, promote regional packs (e.g., Esim Western Europe) or run a limited discount. Ask for end-of-period true-up rights when negotiating.4) What pack sizes maximise margin without harming travellers?Offer a tight set (5GB, 10GB, 20GB). Use data on average consumption; if 10GB users typically consume 7–8GB, pricing can be set to a healthy margin while keeping fair value.5) Do regional eSIMs hurt user experience?No—done right they improve it. Travellers moving between, say, France–Italy–Spain avoid swaps, and your volumes consolidate to better tiers. Highlight coverage pages like Esim Italy to build confidence.6) How often can wholesale tiers or prices change?Typically quarterly, with a price-hold clause. Mid-term adjustments can occur with FX swings or network changes; build 3–5% contingency into your margin model.Next step: Explore tooling, APIs and commercial options in the Simology Partner Hub to structure your tiers, forecast with seasonality, and protect margins.
