Coverage Expansion: 5G in Key Tourist Cities (Q4 2025)

30 Oct 2025

Simology’s Q4 update brings wider, faster 5G to the places travellers actually go. This simology 5g coverage expansion focuses on key tourist cities across North America and Western Europe, boosting peak and average speeds, improving indoor reach, and smoothing handoffs between busy cells. Whether you’re streaming maps, uploading reels, or tethering a laptop, you should feel the difference in airports, old towns, stadiums, and along major transit corridors. Expected real‑world speeds typically range from 100–600 Mbps on mid‑band (n77/n78) with bursts above 1 Gbps in favourable spots. As always, results depend on device support, local spectrum, and network congestion.

Below you’ll find the city lists now covered on our 5G partner footprints, what speeds to expect, device band notes (so you can check compatibility before you buy), and quick steps to get set up. We’ve added practical checklists and pro tips, plus links to our eSIMs by region so you can pick the right plan. If you care about the numbers, we regularly publish real‑world results in our Speed Tests category and will keep updating as new cells light up.

Where 5G just got faster: key tourist cities (Q4 2025)

We’ve expanded 5G access on our partner networks across high‑traffic destinations. Coverage and speed are strongest in dense urban cores and around landmarks, with improving indoor penetration on mid‑band.

United States highlights

Good news if you’re heading to the US—expect stronger mid‑band and more consistent 5G in:

New York City (Manhattan, Brooklyn waterfronts, Midtown transit hubs)
Boston, Washington DC, Philadelphia
Miami, Orlando, Tampa
Chicago, Detroit, Minneapolis
Las Vegas, Phoenix, Denver
Los Angeles, San Diego, San Francisco Bay Area
Seattle, Portland
Honolulu tourist corridors

Typical experience: - Mid‑band 5G (n41/n77): 200–600 Mbps; lower latency vs 4G. - mmWave (n260/n261) pockets in dense zones: 1–3 Gbps bursts at short range. - Sub‑6 indoor coverage improving in malls, convention centres and airports.

France highlights

Urban 3.5 GHz coverage (n78) continues to mature across:

Paris (central arrondissements, business districts, key RER/Metro interchanges)
Nice, Cannes, Marseille
Lyon, Toulouse, Bordeaux
Lille, Strasbourg, Nantes

Typical experience: - n78 mid‑band: 150–500 Mbps, often higher outdoors. - n1/n3 anchors assist indoor coverage; expect 5G to hold in large stations and shopping areas.

Italy highlights

Tourist corridors and historic centres see broader 5G overlays in:

Rome (Termini area, Trastevere edges, Vatican surrounds)
Milan (Duomo, Navigli, business districts)
Florence, Venice, Naples, Bologna
Turin, Verona, Palermo

Typical experience: - n78 mid‑band in city centres: 150–450 Mbps. - n1/n3/n7 support improves handoffs; dense stone architecture can still limit indoor reach—step near windows for best results.

Plan your itinerary with Esim Italy.

Spain highlights

Strong city coverage and coastal hotspots in:

Barcelona (Eixample, Gothic Quarter edges, Sants)
Madrid (Sol, Castellana, Atocha, Chamartín)
Valencia, Seville, Málaga, Bilbao
Balearic tourist zones see seasonal boosts

Typical experience: - n78 mid‑band: 150–500 Mbps. - Stadiums and transport hubs may throttle at peak; off‑peak is significantly faster.

Compare Spanish coverage with Esim Spain.

Western Europe multi‑country

If your trip spans multiple countries, our regional profile is the simplest way to roam on 5G with one eSIM:

Common city pairs: Paris–London–Brussels, Milan–Zurich, Barcelona–Nice, Amsterdam–Berlin corridors
Strongest in major capitals and intercity rail hubs

Typical experience: - n78 mid‑band where available: 150–500 Mbps - Fallback to LTE‑Advanced where 5G is thin; you’ll still see lower latency vs legacy roaming.

Expected speeds and what affects them

Outdoors on mid‑band (n77/n78): 200–600 Mbps is common in North America and Western Europe urban cores.
Indoors: 80–250 Mbps depending on building materials and proximity to windows.
Busy events: 5G may still outperform 4G, but congestion and deprioritisation can mute speeds. Try side streets or step outside large venues.
mmWave in the US: Great for short, line‑of‑sight bursts near stadiums, squares and certain transit hubs. Expect 1–3 Gbps, but coverage is highly localised and falls back quickly.

Remember: your device’s supported bands and firmware matter as much as the local tower.

Device band notes (check before you fly)

Most recent flagship devices support the right mix of bands, but it’s worth verifying to maximise 5G.

United States
Key bands: n5 (850), n41 (2.5), n66 (AWS), n77 (C‑Band), n260/n261 (mmWave)
iPhone 12 and newer: strong Sub‑6; US models also support mmWave.
Pixel 6 and newer; Galaxy S21 and newer: good mid‑band; mmWave support varies by model/region.
France/Italy/Spain/Western Europe
Key bands: n1 (2100), n3 (1800), n7 (2600), n28 (700), n78 (3.5 GHz)
iPhone 12 and newer: excellent n78 support.
Pixel 5 and newer; Galaxy S20 and newer: typically support n78 plus low/mid anchors.

Tips: - Imported phones may lack local bands. Double‑check your exact model number. - Dual‑SIM: set your Simology line as “Primary” for data and enable 5G Auto/5G On. - Keep device software up to date to ensure the latest carrier settings.

How to get 5G on Simology (step‑by‑step)

Pick your plan - Single‑country or regional: try Esim United States, Esim France, Esim Italy, Esim Spain, or Esim Western Europe. Multi‑country travellers should consider Esim North America or Western Europe for seamless roaming.
Install your eSIM - Scan the QR code or use activation codes in your order email. Keep Wi‑Fi on during install.
Set Simology as your data line - On iOS: Settings > Mobile Data > Default Voice Line/Data > choose your Simology eSIM. Turn on 5G Auto/5G On. - On Android: Settings > Network & Internet > SIMs > turn on Mobile data for Simology. Select 5G preferred.
Check APN if prompted - Most profiles auto‑configure. If needed, follow the APN values in your confirmation email.
Restart and test - Give your phone 30–60 seconds on reboot to register on 5G. Run a quick speed test near a window or outdoors.

Before‑you‑fly checklist

Confirm your phone’s 5G band support for your destination.
Update iOS/Android and carrier settings.
Turn off Low Data Mode/Data Saver for best performance.
Enable VoLTE/Wi‑Fi Calling for reliable voice (when available).
Download offline maps just in case indoor coverage is patchy.
Bring a small power bank; 5G can use more battery in weak‑signal zones.

Pro tips to maximise speed and stability

Move 5–10 metres: stepping outside or towards a window can double your throughput.
Avoid crowd hotspots during events; a nearby side street may give better quality.
Toggle Airplane Mode for 5–10 seconds if you lose 5G after leaving the metro or a tunnel.
Prefer mid‑band: if your phone shows “5G” but feels slow, you may be on a low‑band 5G NR carrier layer. A quick cell reselection (Airplane Mode toggle) can lock you onto faster mid‑band.
Tethering: use the 5 GHz hotspot band for cleaner spectrum, especially in apartment blocks and hotels.

How we measure performance

We combine crowd‑sourced session analytics (latency, throughput, packet loss) with in‑city walk tests near airports, major stations, popular attractions and conference venues. We prioritise real‑world traveller routes over lab peaks. You’ll see the methodology and raw screenshots in our Speed Tests posts. Expect ongoing updates as new spectrum is lit, additional small cells come online, and stadiums add capacity.

FAQs

Will I get 5G everywhere in these cities?
No network offers 100% 5G. Expect strong mid‑band in central areas and along major transport, with occasional fallbacks to LTE indoors or in narrow streets. Our profiles roam across partner networks to keep you on the best available layer.
Do I need a specific phone model for this update?
Any 5G‑capable, eSIM‑compatible device with the right bands will benefit. iPhone 12+/Pixel 5+/modern Galaxy flagships are safe bets. Check your exact model’s band list against the notes above.
Can I use mmWave in the US?
In select dense spots, yes—if your device supports n260/n261 (US‑sold iPhones and certain Androids). mmWave coverage is hyper‑local; think stadium plazas and parts of downtown blocks. Most of your day‑to‑day will be fast Sub‑6 mid‑band.
How do I check coverage for my itinerary?
Start with our regional plan pages (Esim United States, Esim France, Esim Italy, Esim Spain, Esim Western Europe, Esim North America) and city notes on Destinations. We also post recent real‑world numbers in our Speed Tests articles.
Is tethering allowed on Simology 5G plans?
Yes on most plans, within fair‑use limits. Performance depends on your device radio and signal quality. Use the 5 GHz hotspot band for best results and keep the phone near a window for steadier mid‑band.
What if speeds feel slow?
Try: move a few metres, toggle Airplane Mode, ensure 5G Auto/Preferred is on, switch off Low Data Mode/Data Saver, and check for pending OS/carrier updates. If issues persist, contact support with your device model, location and a screenshot of your network status.

What this means for your next trip

In short: you’ll see faster uploads and more consistent streaming in the places visitors actually spend time—downtowns, transport hubs, and major sights—across the US, France, Italy, Spain, and wider Western Europe. If you travel for work, pooled data and easy provisioning via For Business make multi‑city trips simpler. If you’re a partner, the Partner Hub has rollout notes and assets.

Next step: browse city‑by‑city options and pick the right eSIM for your route on Destinations.

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.

Thailand eSIM & Mobile Internet Guide (2025): Speeds, Island Coverage, eKYC

Planning Thailand for 2025? An eSIM is the easiest way to land connected, whether you’re hopping BTS/MRT in Bangkok or island‑hopping from Phuket to Koh Samui. Coverage across Thailand’s tourist corridors is strong, 5G is widespread in cities, and 4G LTE reaches most coastlines. The main gotcha is eKYC (electronic identity verification): Thai regulations require SIM registration, and many Thailand eSIMs ask for a quick passport selfie check before they activate. Get that done ahead of arrival and you’ll switch on data at the airport.This guide covers real‑world speeds (including on the BTS/MRT), how signal holds up on popular islands, eKYC steps and pitfalls, and the best way to set up your phone for a smooth trip. If you’re choosing between plans, we’ll also help you size your data, understand tethering rules, and avoid post‑cap throttling surprises. Ready to pick a plan? Browse Thailand options on Destinations.Quick take: Should you get an eSIM for Thailand?Yes—if your phone supports eSIM, it’s the most convenient and typically cheapest way to get Thai data on arrival.5G is robust in Bangkok, Chiang Mai, and Phuket Town; 4G is strong across most beach areas and intercity routes.On islands, expect solid coverage in towns and popular beaches, with patchy service in dense jungle, headlands, and marine parks.Bangkok’s BTS/MRT corridors are well covered, including underground sections; short dropouts can happen between stations.Complete eKYC before you fly if your provider requires it; activation is usually minutes once verified.Coverage and speeds in 2025: what to expectThe networks at a glanceAIS and True (True/dtac combined under True Corp) operate the largest mobile networks.5G primarily uses mid‑band (n41/2600 MHz) for speed and low‑band (n28/700 MHz) for reach; 4G LTE runs across common bands (1/3/8/28).Any modern iPhone (XR or newer) and most recent Android flagships support these bands. Avoid China‑only variants without eSIM.Real‑world speeds by locationActual speeds depend on time of day, crowding, and your exact spot:Bangkok core (Siam, Silom, Asok, Ari, riverside): 5G typically 120–300 Mbps, bursts higher; 4G 25–80 Mbps.Airports (BKK/DMK): 50–150 Mbps with busy‑hour variability.Phuket (Patong, Karon, Kata, Phuket Town): 4G/5G 50–200 Mbps; headlands and lesser‑visited bays can dip to 5–20 Mbps.Phi Phi & Railay: town areas 10–60 Mbps, midday congestion common; trails and cliffs can drop to fringe 4G or 3G‑like speeds.Koh Samui (Chaweng, Lamai, Bophut): 60–180 Mbps in town/beach zones; interior hills 2–15 Mbps.Koh Phangan (Thong Sala, Haad Rin): 20–90 Mbps around towns; east‑coast coves patchier.Koh Tao: variable 5–50 Mbps near Mae Haad/Sairee; remote bays may be marginal.Intercity highways (Bangkok–Ayutthaya, Chiang Mai surroundings): generally stable 4G with pockets of 5G near towns.These ranges reflect recent traveller tests and public network reports; weather and maintenance can affect results.BTS/MRT coverage explainedBTS Skytrain (Sukhumvit/Silom lines): excellent 4G/5G on platforms and trains; brief handover dips between stations.MRT Blue & Purple (underground): strong 4G/5G within stations and most tunnels; occasional short dead zones in deeper sections.Airport Rail Link: consistent 4G; 5G appears in denser areas. Pro tip: If 5G feels “sticky” in tunnels (high ping/packet loss), lock your device to 4G/LTE for the ride, then re‑enable 5G later.Islands and ferry routesPhuket–Phi Phi–Krabi ferries: signal fluctuates offshore; expect 0–20 Mbps mid‑channel, then recovery near land.Surat Thani–Koh Samui/Phangan ferries: coverage improves near Don Sak pier and the islands; plan offline content for the crossing.Marine parks (Similan, Ang Thong): minimal to no service—download maps and tickets in advance.Buying and activating a Thailand eSIM (with eKYC)Follow this once and you’re set.1) Check compatibility - Confirm your device supports eSIM and is unlocked. - Dual‑SIM users: decide which SIM handles data during the trip.2) Choose your plan - Pick a Thailand eSIM on Destinations with enough data for your dates. - Look for “hotspot/tethering allowed” if you intend to share data. - If you need regional coverage beyond Thailand (e.g., onward to the US), also see Esim North America or Esim United States for separate legs.3) Complete eKYC (if required) - Upload a passport photo page and a live selfie. - Ensure name/spelling matches your booking exactly (no nicknames).4) Install the eSIM - Scan the QR or use the install code; label it “Thailand”. - Keep your home SIM on for iMessage/WhatsApp continuity if needed.5) Configure data - Set the Thailand eSIM as “Mobile Data”. - Turn “Data Roaming” ON for the Thailand eSIM profile (this is required even though you’re in Thailand). - APN usually auto‑fills; if not provided, enter the APN from your plan instructions.6) Test before travel (recommended) - If your plan allows pre‑activation, do the install over home Wi‑Fi to avoid airport scrambling.eKYC quirks and how to avoid delaysLighting and framing matter: photograph the entire passport page, MRZ visible, no glare.Remove hats/glasses for the selfie. Match your look to your passport photo where possible.Non‑Latin names: use the Latin transcription exactly as on your MRZ/passport data line.Processing times: automated checks often approve in minutes; manual reviews can take longer outside Thai business hours—do it a day before departure.Until eKYC is approved, some plans won’t attach to the network. Don’t leave it to the arrival queue.Plan selection: data, hotspot, and throttlingTypical tourist use: 3–5 GB/week for maps, ride‑hailing, chat, casual socials; 8–12 GB/week if you stream video, reels, or hotspot a laptop.“Unlimited” often means high‑speed to a cap (e.g., 2–10 GB/day) then throttled to 1–10 Mbps. This is fine for maps and chat, not for HD video.Tethering: most data‑only Thailand eSIMs allow hotspot, but some “unlimited” tiers restrict it. Check plan details.Local number: many travel eSIMs are data‑only (no Thai number). Apps like Grab, LINE, WhatsApp work fine without a local number.Trip chaining: if you’re continuing to Europe later, consider separate regional plans like Esim Western Europe, Esim France, Esim Italy, or Esim Spain.Device setup checklist (iPhone and Android)iPhone (iOS 16+) - Settings > Mobile Data > Add eSIM > Use QR or Enter Details. - Label the line “Thailand”. - Mobile Data: Thailand eSIM. Default Voice: your home SIM (optional). - Data Roaming: ON for Thailand eSIM. - iMessage & FaceTime: keep tied to your primary number/email. - If APN is required: Mobile Data Network > enter APN from instructions.Android (Pixel/Samsung recent) - Settings > Network & Internet > SIMs > Add eSIM. - Mobile data: Thailand eSIM. Data roaming: ON (for the Thailand eSIM). - Preferred network type: 5G/4G (or LTE only for stability on ferries/tunnels). - Enter APN if prompted.Dual‑SIM hygiene - Disable “Allow Mobile Data Switching” if your phone keeps jumping back to your home SIM. - Prioritise the Thailand eSIM for data to avoid roaming charges on your primary line.Troubleshooting in 60 secondsNo connection after install: toggle Airplane Mode for 10 seconds; ensure Data Roaming is ON for the Thailand eSIM.Still no data: manually select the recommended network in your SIM’s instructions; try forcing LTE/4G temporarily.APN empty: enter the APN exactly as supplied; save and reboot.eKYC pending: you won’t attach until verified—recheck the passport/selfie quality and resubmit.Slow in crowds: lock to 4G/LTE for lower latency, or move a few metres for a different sector.iMessage/WhatsApp not receiving: keep your home line active for services linked to your number; data stays on the Thailand eSIM.Pro tips for travellersDownload offline Google Maps for Bangkok, Phuket, Samui, and any national parks you’ll visit.For BTS/MRT, 4G is often the smoothest in tunnels; switch back to 5G for big downloads.On islands, higher ground isn’t always better—turn a corner along the beach to change cell sectors.Ferry days: preload podcasts and boarding passes; expect dead zones mid‑channel.If you rely on hotspot, avoid “unlimited” plans with hotspot limits; pick a clear data‑bucket plan.Business trip or team travel? Centralise procurement and compliance via For Business. Need referral tools? See Partner Hub.Planning more trips?After Thailand, keep it simple with region‑ready options: - North American leg? Check Esim North America or single‑country Esim United States. - Europe coming up? Start with Esim Western Europe or country picks like Esim France, Esim Italy, and Esim Spain.FAQ1) Do I really need to complete eKYC for a Thailand eSIM? - In most cases, yes. Thai regulations require SIM registration. Many providers handle this remotely with a passport scan and selfie. Without eKYC, activation may be delayed or restricted.2) Will my eSIM work on Bangkok’s BTS and MRT? - Yes. Coverage on platforms, trains, and tunnels is generally strong. If you notice lag on 5G underground, switch to 4G for the ride.3) Can I hotspot my laptop from a Thailand eSIM? - Usually. Many plans allow tethering, but some “unlimited” tiers cap or block hotspot. Check your plan’s hotspot policy before purchase.4) How much data should I buy for 10–14 days? - Light users: 6–10 GB. Typical travellers: 12–20 GB. Heavy streamers or hotspot users: 25–40 GB. If in doubt, choose a plan with easy top‑ups.5) Will I get a Thai phone number? - Data‑only travel eSIMs often don’t include a local number. That’s fine for maps, ride‑hailing, social, and VoIP. If you need voice/SMS, pick a plan that explicitly includes them.6) What speeds should I expect on islands like Phuket and Koh Samui? - In town and main beaches, 50–200 Mbps is common on 4G/5G. Expect slower or patchier service in jungle interiors, headlands, and marine parks.Next step: Compare Thailand eSIM plans and get set up in minutes on Destinations.

Rome Speed Test: FCO Airport, Centro Storico, Termini – Tourist Reality

Rome is dense, beautiful, and busy – which makes mobile data a moving target. We ran a rome mobile speed test across three places tourists actually use data: Fiumicino (FCO) Airport, the Centro Storico (Trevi, Pantheon, Piazza Navona), and Roma Termini station. We tested multiple times per day, across the major Italian networks (TIM, Vodafone, WindTre, Iliad) with modern 5G phones, and compared them to typical hotel Wi‑Fi. The short story: 5G beats most hotel Wi‑Fi, but crowds matter. Expect fast airport and early‑morning speeds, mid‑day slowdowns at Trevi and Termini, and patchy performance in underground or thick‑walled areas.Below you’ll find our methodology, location‑by‑location results, practical set‑up tips, and an open CSV snapshot of readings. If you’re continuing beyond Italy, we also note options for regional eSIMs, so you can choose what fits your route and data appetite.

For realism, we included peak tourist times and indoor spots with heavy attenuation.Visitor quick takeawaysAirport wins: FCO 5G is generally strong; quick maps, rides, and check‑ins are painless.Centro crowds crush capacity: Trevi at mid‑day drops to “just usable” on some networks; dawn and late evening are much faster.Termini is two worlds: decent outside on the piazza and platforms; degraded in the metro hall and under heavy footfall in the concourse.5G beats hotel Wi‑Fi: mid‑range hotel Wi‑Fi in Centro often tested 10–30 Mbps with high latency; 5G commonly delivered 120–350 Mbps down and far lower latency.eSIM works well: an Italy‑only eSIM is the best value if staying in Rome; regional eSIMs suit multi‑country trips.For an Italy‑focused plan, start with Esim Italy. If you’re covering multiple countries, see Esim Western Europe, or if you’re heading stateside before/after, Esim United States or Esim North America.Results by locationFCO Airport (Fiumicino) – Terminal 3 and trainsMorning arrivals (08:00–10:00):Vodafone 5G: 280–420 Mbps down, 35–60 up, 18–25 msTIM 5G: 220–360 down, 30–50 up, 19–27 msWindTre 5G: 120–220 down, 15–30 up, 25–35 msIliad 4G/5G NSA mix: 70–140 down, 8–20 up, 30–45 msMid‑day (12:00–14:00) arrivals hall congestion:The above figures typically halved; we saw lows of 40–80 Mbps on WindTre and Iliad. Still fine for maps and ride‑hailing, but large downloads slowed.Train platforms (SkyTrain, Leonardo Express):Slightly better than arrivals hall; cleaner radio environment yielded 20–30% faster medians.Bottom line: great for first‑hour needs. If you need to upload big media, do it before leaving the terminal area or on the express platforms.Centro Storico – Trevi, Pantheon, Piazza NavonaTrevi Fountain (mid‑day peak):TIM/Vodafone 5G often dropped to 40–120 Mbps down, 10–30 up, latency 25–45 ms.WindTre/Iliad varied widely, with worst runs near 15–40 Mbps down at peak crowd density.Trevi (early morning around sunrise):TIM/Vodafone back to 200–350 Mbps down, 30–45 up; WindTre around 120–200; Iliad 80–160.Pantheon area:Walled streets and stone facades attenuate signal. Even at off‑peak, expect 80–220 Mbps down on 5G with occasional handoffs to 4G inside cafes.Piazza Navona:More open space, higher medians: 180–400 Mbps down across TIM/Vodafone; WindTre 140–250; Iliad 100–180.Tip: step a few metres away from the densest crowd or into an open piazza; performance jumps immediately, even on the same network.Roma Termini – concourse, platforms, metroMain concourse (17:00–19:00 rush):Capacity strain evident. TIM/Vodafone 5G: 60–180 Mbps down, 10–25 up. WindTre/Iliad: 20–90 down, 5–15 up.Platforms (outdoors, near platform ends):Higher, cleaner speeds: 150–250 Mbps down on TIM/Vodafone; 100–180 on WindTre; 80–150 on Iliad.Metro hall and underground corridors:Expect 4G fallback and single‑digit uploads. We saw 5–25 Mbps down, 2–8 up, with jitter. Fine for messaging; video calls stutter.If your itinerary relies on video calls from Termini, take them near the outdoor edges of the platforms or the front plaza (Piazza dei Cinquecento), not inside the metro hall.Hotel Wi‑Fi vs 5G in RomeWe ran side‑by‑side tests in two mid‑range hotels near Trevi and the Pantheon:Typical hotel Wi‑Fi (2.4 GHz, shared backhaul):10–30 Mbps down, 5–15 up, 60–120 ms latency. Evening slowdowns were dramatic when tours returned.5G mobile (same room, window side):120–350 Mbps down, 20–45 up, 18–35 ms latency on TIM/Vodafone; 80–200 on WindTre/Iliad.Conclusions: - Most mid‑range hotel Wi‑Fi is serviceable for email and basic streaming but struggles with large cloud sync and group video calls. - 5G is the safer default for uploads, HD calls and tethering a laptop. Keep Wi‑Fi as a backup.If you’re staying Italy‑only, choose a local plan via Esim Italy. For onward travel to Spain or France, look at Esim Spain and Esim France, or a single regional pass via Esim Western Europe.How to get reliable data in RomeQuick setup checklistBefore you flyBuy an eSIM and install it while you have stable Wi‑Fi. For Italy‑only, use Esim Italy. Multi‑country? Use Esim Western Europe.Update iOS/Android and carrier settings; disable Low Data Mode/Data Saver.Set 5G to Auto (iOS) or Preferred (Android).On arrival at FCOToggle Airplane Mode off/on once. Ensure Data Roaming is ON for your travel eSIM.If speeds are low in arrivals, walk to the train platforms; re‑run the test.In the cityFavour open squares for calls/uploads; avoid dense indoor marble corridors during rush hours.For video calls at Termini, move outside or towards platform ends.Don’t rely solely on hotel Wi‑Fi for critical work.Pro tipsKeep two lines active if possible: a local eSIM for data and your home SIM on voice/SMS only.Use a reputable speed test server in Rome first; if it looks congested, switch to Milan for a second opinion.Turn off iCloud/Google Photos background sync before entering crowded hotspots; upload later in a clearer cell.If your device keeps dropping to 4G, lock to 5G Auto (not 5G On) to avoid sticky weak 5G cells.Businesses moving teams through Rome can pre‑stage eSIMs and monitor usage centrally via For Business. Travel brands and agencies can integrate our field data and provisioning through the Partner Hub.The dataset (open CSV snapshot)We publish an open snapshot for reproducibility.

Good regional options: Esim France and Esim Spain, or a broader bundle via Esim Western Europe. Coming from or heading to the US? Keep continuity with Esim United States or the continental Esim North America.FAQWhat’s the fastest network in Rome right now?Results vary by street and time. In our runs TIM and Vodafone generally led in 5G around FCO, Centro, and Termini, with WindTre and Iliad close behind outdoors and more variable indoors. Always test where you actually stand.Is 5G available everywhere in Rome?No. 5G covers most central outdoor areas but can drop to 4G inside historic buildings, underground, and in narrow streets. 5G Auto usually gives the best balance.Should I rely on hotel Wi‑Fi?Use it as a backup. Our tests showed many mid‑range hotels delivered 10–30 Mbps with high latency at peak times. Mobile 5G was usually faster and more stable for calls and uploads.Which eSIM should I buy for a Rome city break?If you’ll stay in Italy, go local with Esim Italy for best value and performance. If you’re crossing borders, pick a regional pass via Esim Western Europe.Will my EU plan roam fine in Italy?Yes, EU‑regulated roaming typically works, but fair‑use caps may apply. If you’re close to your cap or need better performance, a local eSIM can help.I need guaranteed performance for a team event at Termini. Any advice?Stage SIMs ahead of time, test the exact area at the event hour, and position staff outdoors or near platform edges for uplinks.
