New York City Speed Test: JFK/EWR Airports, Midtown, Subway Platforms

New York is a hard stress test for any mobile network. We spent two days measuring real‑world performance at JFK and Newark (EWR) airports, across busy Midtown blocks, and on multiple subway platforms. Our aim: practical guidance for travellers deciding between airport Wi‑Fi and 5G, whether Midtown crowds crush throughput, and how usable platforms are while you wait for a train. This report prioritises lived experience over lab peaks. We ran multiple tests at commuter peak and off‑peak, indoors and outdoors, and we compared against three Midtown hotel Wi‑Fi networks. You’ll find a summary of results, location‑by‑location notes, and a copy‑paste CSV so you can inspect the data. If you’re planning a US trip, pair this with an eSIM from our Esim United States range or multi‑country cover via Esim North America.

What we tested and how

Devices and profiles

  • Two recent 5G phones (Sub‑6 with C‑band and mid‑band support).
  • eSIM profiles on mainstream US networks plus an international roaming eSIM.
  • Tests performed with VPN off, battery above 40%, and mobile data preference set to 5G Auto.

Locations and times

  • Airports: JFK Terminal 4 departures (check‑in, security, two gate areas) and Terminal 8 concourse; EWR Terminal A (new concourse) and Terminal C food court.
  • Midtown: Times Square (7th Ave/45th), Bryant Park, Herald Square, Grand Central exterior, and a 33rd St office lobby.
  • Subway platforms: Times Sq–42 St (A/C/E and 1/2/3), Grand Central–42 St (4/5/6), 34 St–Herald Sq (B/D/F/M/N/Q/R/W), and 14 St–Union Sq (L/4/5/6).
  • Time windows: weekday morning commute (07:30–09:30), lunch (12:00–14:00), evening (17:00–19:00), late night (22:00–23:00).

Method

  • Three runs per spot via Speedtest app; we logged downlink, uplink, latency, jitter, signal strength, and RAT (5G/4G).
  • Where venue Wi‑Fi existed (free airport Wi‑Fi and three Midtown hotels), we ran two Wi‑Fi tests per spot on 5 GHz networks.
  • We averaged per spot and noted congestion spikes, captive portals, and any dead zones.

Headline results at a glance

  • Airports: JFK 5G mid‑band generally fast and consistent (150–400 Mbps down; 15–50 Mbps up; 18–35 ms latency). EWR A/C similar or slightly lower (120–320 Mbps down). Free airport Wi‑Fi varied widely (25–180 Mbps down), with higher latency and occasional captive portals.
  • Midtown streets: Solid mid‑band 5G when outdoors (80–350 Mbps down) but congestion dips around Times Square at lunchtime and pre‑theatre, where some runs fell to 20–60 Mbps. Latency on mobile stayed sub‑40 ms even under load.
  • Inside buildings: Lobbies and deep interiors dropped to 4G or low‑band 5G in some cases; speeds ranged 10–80 Mbps down with higher jitter.
  • Subway platforms: Coverage is expanding; most major stations tested had usable LTE/5G on platforms. Typical speeds 8–90 Mbps down, 2–25 Mbps up, with sporadic “No service” pockets in older sections. In‑tunnel between stations remains hit‑and‑miss.
  • Hotel Wi‑Fi vs 5G: Two hotels delivered 30–60 Mbps with 60–120 ms latency and aggressive captive portals; one business‑class property delivered 120–220 Mbps down but still 30–60 ms latency. 5G usually beat Wi‑Fi for upload and latency, and matched or exceeded download at peak times.

Location‑by‑location findings

JFK Airport (Terminal 4 and 8)

  • Check‑in and security halls (T4): 5G mid‑band was strong across operators with 180–320 Mbps down and 15–40 Mbps up. Free Wi‑Fi was usable (40–120 Mbps down) but required captive portal acceptance; latency 35–70 ms.
  • Gate areas (T4 B concourse): Best mobile results of the airport, frequently 250–400 Mbps down on mid‑band, and steady 20–45 Mbps up. Video calls were smooth even with background syncing. Wi‑Fi here fluctuated from 25 to 110 Mbps depending on nearby users.
  • Terminal 8 concourse: Slightly lower medians (150–260 Mbps down). We noted uplink dips in the 10–20 Mbps range at peak boarding times.

Pro tips: - If Wi‑Fi captive portals fail, toggle Wi‑Fi off and rely on 5G for faster onboarding and lower latency. - Avoid deep corners behind pillars near gates; step into the main concourse for better 5G mid‑band.

Newark Liberty (EWR Terminal A and C)

  • Terminal A (new building): Consistent mid‑band 5G with 160–300 Mbps down, 18–40 Mbps up, 20–32 ms latency. Free Wi‑Fi delivered 60–150 Mbps down in open seating areas, but dipped under 20 Mbps near crowded food zones.
  • Terminal C food court: Higher contention; mobile still acceptable (120–220 Mbps down). Wi‑Fi varied the most here (10–90 Mbps), with notable jitter during peak meal windows.

Traveller takeaway: - At both airports, mobile 5G was the safer default for uploads (docs to cloud, messaging attachments). Use Wi‑Fi only when you need to save data or if you find an uncrowded access point.

Midtown Manhattan streets and hotels

  • Streets and plazas: Outdoor mid‑band 5G carried well along 6th and 7th Avenues. Lunchtime at Times Square saw the steepest drops; several tests fell below 50 Mbps down due to crowd density. Even then, latency held under ~45 ms, keeping maps, rideshare, and messaging responsive.
  • Lobbies and lifts: We saw handoffs to low‑band 5G or LTE with downlink in the 10–40 Mbps range. Uploads were the pain point inside (often <10 Mbps), affecting cloud photo backup and large email sends.
  • Hotels (three properties):
  • Business hotel near Bryant Park: 120–220/20–40 Mbps with predictable performance but higher latency (30–60 ms) than mobile.
  • Two mid‑range hotels near Herald Square and Times Square: 20–60/5–15 Mbps, captive portals, device quotas, and occasional throttling at night.
  • Versus 5G: Mobile 5G beat or matched hotel Wi‑Fi on upload and latency in all three cases, and beat two hotels on download.

Pro tips: - If your video call matters, tether from 5G in Midtown rather than relying on mid‑range hotel Wi‑Fi. - Try a window‑side spot for stronger 5G when indoors; walls and metallic façades can heavily attenuate mid‑band.

Subway platforms: coverage and speed reality

  • Platform coverage is expanding station by station. We found usable LTE/5G at Times Sq–42 St, Grand Central–42 St, Herald Sq, and Union Sq platforms.
  • Typical results: 8–90 Mbps down, 2–25 Mbps up, 30–60 ms latency. Newer stations and renovated sections skewed higher.
  • Dead zones: Some corners and transfer corridors still drop to “No service” or edge‑LTE. Between stations, expect intermittent service; do not rely on continuous connectivity for real‑time navigation or calls.

Platform tips: - Download offline maps before you go. - Send large attachments while still on the platform; uplink often collapses once the train departs. - If you need a hotspot, stand near stairwells or open mezzanines where signals tend to be stronger.

5G vs hotel Wi‑Fi: which should you pick?

Use mobile 5G when: - You need low latency (video calls, live collaboration). - Uploads matter (cloud backups, sending docs). - Wi‑Fi is captive‑portal‑gated or throttled.

Use Wi‑Fi when: - You’re preserving roaming data or on a tight cap. - You can access a premium or business‑grade SSID. - You’re downloading large app updates off‑peak.

Checklist to decide in 30 seconds: 1. Test ping and upload (not just download). If latency >60 ms and upload <5 Mbps on Wi‑Fi, switch to 5G. 2. If your phone shows weak 5G indoors, move closer to windows or try Wi‑Fi. 3. Avoid VPN during tests; it skews latency. Re‑enable after. 4. Disable low‑power or data‑saver modes for accurate benchmarking. 5. For sensitive work, use personal 5G + VPN rather than shared hotel Wi‑Fi.

How to replicate our nyc speed test mobile

Step‑by‑step: 1. Prepare your device: update OS, ensure 5G Auto is on, disable VPN, and charge >40%. 2. Install two speed apps (e.g., Speedtest and Fast). Close all other network‑heavy apps. 3. At each spot, run three tests on mobile data, 30–60 seconds apart. Note RAT (5G/4G) and signal bars/dBm if available. 4. If Wi‑Fi exists, join the main SSID, complete any captive portal, and run two tests. 5. Log results in a simple CSV with: datetime (local), location, lat/long (approx), network tech, down/up/latency/jitter, signal_dBm, and notes. 6. Airplane mode toggle between locations to force a clean network attach.

Pro tips: - Test at different times; NYC congestion is time‑dependent. - Stand still during tests; movement changes cell selection and beamforming. - For consistent comparisons on future trips (e.g., Paris, Milan, Barcelona), repeat the same method and compare with our Esim France, Esim Italy, and Esim Spain travellers’ notes, or cover a broader trip with Esim Western Europe.

Traveller recommendations

  • Primary SIM choice: For single‑country travel, a US eSIM is simplest; see our Esim United States options with generous high‑speed data. Multi‑city North America itinerary? Use Esim North America.
  • Business travellers: Consider a plan with strong uplink and hotspot allowance for Midtown calls and airport uploads. If you manage a team, our For Business page outlines pooled data and spend controls.
  • Partners and events: If you operate venues or events in NYC and want predictable connectivity for attendees, collaborate via our Partner Hub.
  • Pre‑trip planning: Check other city reports on Destinations to benchmark expectations.

FAQ

  • Is mobile 5G faster than airport Wi‑Fi in NYC?
    Usually, yes—especially for uploads and latency. Download speeds can be similar when Wi‑Fi is uncongested.
  • Will my phone work on subway platforms?
    At major stations, yes, with usable LTE/5G on platforms. Expect gaps in corridors and between stations.
  • What speeds should I expect in Times Square?
    Outdoors on 5G, 50–250 Mbps is typical, but lunch and pre‑theatre peaks can dip below that due to crowd density.
  • Is hotel Wi‑Fi reliable for video calls?
    It varies. Business‑grade Wi‑Fi can work, but many hotels have higher latency or throttling. Tethering over 5G is often smoother.
  • Do I need a US‑specific eSIM for best speeds?
    It helps. A local plan from Esim United States typically provides better performance and predictability than pure roaming. If you’re visiting Canada too, consider Esim North America.
  • Where can I find more city speed tests?

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.

Mobile Bands by Region: Will Your Phone Work in the USA, Europe, Asia?

Mobile Bands by Region: Will Your Phone Work in the USA, Europe, Asia?

Travelling with your own phone is easy—until it isn’t. Mobile networks use different frequency bands in different parts of the world, and your device must support the right ones to get strong 4G/LTE coverage (and voice, via VoLTE) abroad. If you’ve ever landed to “No service” or painfully slow data, band compatibility was likely the culprit. This guide gives you a traveller-first way to check, fast. You’ll find the key LTE bands by region, simple checklists to confirm compatibility, and pro tips to avoid surprises—plus direct links to regional eSIMs so you can be online the moment you land. Use the band tables to see what matters in the USA, Europe and Asia, then run a quick device check before you buy. If you only remember one thing: you don’t need every band, but you do need the right few for where you’re going.Mobile bands 101 (the two-minute refresher)A “band” is a chunk of radio frequency used by mobile networks. LTE bands have numbers (e.g., Band 3, Band 20).Regions deploy different mixes of bands. Your phone must support the local bands to get 4G data and VoLTE calls.FDD vs TDD: Some regions (notably China/India) use TDD bands like 40/41. Many phones support both FDD and TDD, but budget or older models may not.3G/2G shutdowns: The USA has shut down 3G and legacy CDMA. Without VoLTE, calls won’t work. Several countries in Europe/Asia still run 3G, but support is shrinking.5G is great, but 4G/LTE is still the baseline for reliable coverage. Check LTE first; treat 5G as a bonus.Pro tip: “Quad‑band” used to mean 2G/GSM compatibility, not LTE. For modern travel, look for LTE/5G band support, not just GSM.The fast compatibility checklist1) Find your phone’s supported bands - iPhone: Settings &gt; General &gt; About &gt; Legal &gt; Regulatory, then cross-check on Apple’s specs page. - Android: Settings &gt; About phone &gt; Hardware information, then confirm on the manufacturer’s specs page or model datasheet. - Pro tip: Model numbers vary by region. Verify the exact model (e.g., SM‑S91xB vs SM‑S91xU).2) Check the destination’s key LTE bands - Use the regional tables below as a quick filter. - Then confirm your specific country on our Destinations page (with device checker).3) Confirm VoLTE support - USA travel requires VoLTE for calls (3G is off). Ensure your device supports VoLTE and that it’s enabled.4) eSIM and carrier lock - Ensure your phone is carrier‑unlocked and supports eSIM. - Choose a regional eSIM: for example, Esim United States or Esim Western Europe.5) Install and test before you fly - Add the eSIM profile, set the APN (if needed), enable data roaming, and run a speed test on arrival.Pro tips: - You don’t need every band—having the main coverage band(s) plus at least one capacity band usually suffices. - Rural coverage often relies on low‑frequency bands (700/800 MHz like B12/B13/B20/B28). Don’t skip these if you’re leaving big cities.LTE bands by region: what really mattersNorth America (USA and Canada)In the USA, each operator leans on a small set of critical LTE bands.

Mid‑range or region‑specific variants may drop one or two—double‑check.How to set up your phone and eSIM before you fly1) Verify compatibility - Match your phone’s LTE bands to the country’s key bands using this guide and Destinations.2) Pick a regional plan - USA/Canada: Esim North America or country‑specific Esim United States. - Western Europe multi‑city: Esim Western Europe. - Single‑country trips: Esim France, Esim Italy, Esim Spain.3) Install the eSIM - Add via QR or in‑app; label it (e.g., “Trip eSIM”). - Set it as the mobile data line; leave your home line for calls/SMS if needed.4) Enable VoLTE and data roaming - iPhone: Settings &gt; Mobile Data &gt; your eSIM &gt; Voice &amp; Data &gt; enable LTE/VoLTE. - Android: Settings wording varies; ensure 4G preferred and VoLTE toggled on.5) Configure APN if required - Most eSIMs auto‑configure. If speeds are odd, re‑check APN settings provided at purchase.6) On arrival: test quickly - Toggle flight mode off/on, check bars, run a speed test. Move to a window for initial registration if signal is weak.For team or multi‑trip planning, see For Business. Partners and resellers can explore the Partner Hub.FAQsQ: Do I need every local LTE band to get coverage? A: No. Aim for the main coverage band(s) plus at least one capacity band. In Europe that’s typically 20/28 + 3/7; in the USA it’s 12/13/71 + 2/4/66.Q: Will my phone make calls in the USA? A: Only if it supports VoLTE and the carrier recognises your device for VoLTE. 3G is shut down. Ensure VoLTE is enabled and consider mainstream devices for best compatibility.Q: My phone is “GSM unlocked.” Is that enough? A: Not necessarily. “GSM unlocked” doesn’t guarantee LTE band support. Check the specific LTE bands your device supports against the destination’s bands.Q: What about 5G bands—should I care? A: Treat 5G as a bonus. LTE is the baseline for reliable coverage. If your phone matches the key LTE bands, you’ll be fine; 5G adds speed where available.Q: How do I find my phone’s exact bands? A: Check the manufacturer’s specs for your precise model number (e.g., on the retail box or in Settings). Cross‑reference with the tables above or use the device checker on our Destinations page.Q: Will a European phone work in North America (and vice versa)? A: Often yes, but performance varies. Many EU phones lack Band 71 (USA rural) and some USA models lack Band 20 (EU rural). City usage may be fine; rural coverage can suffer.The bottom lineMatch your phone’s LTE bands to where you’re going, prioritise the few that matter, and enable VoLTE. Choose a regional eSIM that fits your itinerary and install it before you fly.Next step: Check your destination and run a quick device compatibility check on our Destinations page, then pick the right plan (e.g., Esim North America or Esim Western Europe) to travel connected.

Best eSIM for International Travel (2025): Simology vs Airalo vs Holafly vs Nomad

Best eSIM for International Travel (2025): Simology vs Airalo vs Holafly vs Nomad

Planning data for a multi-country trip shouldn’t be a gamble. The best eSIM for international travel in 2025 blends wide coverage, predictable pricing, and hassle-free switching when a local network gets congested or weak. That’s why our top criterion this year is multi‑network switching: the ability for your eSIM to use more than one carrier in the same country and automatically move to a stronger signal. It’s the biggest reliability upgrade for travellers since eSIMs arrived.In this guide, we compare Simology, Airalo, Holafly, and Nomad against criteria that matter on the road: real-world coverage, speed access (4G/5G), hotspot support, regional roaming, plan flexibility, and support. We’ll flag where each provider fits best, give you practical checklists, and link straight to destination pages so you can price up your route in minutes. If you’re heading to Europe, North America, or a single country like the US, France, Italy or Spain, you’ll find specific plan pointers below and via our Destinations.How we compared (criteria that matter in 2025)Coverage redundancy: Does the eSIM use multiple local networks in-country and switch automatically?Speed access: Consistent 4G/5G access; realistic speeds at peak times; fair use policies.Plan design: Single-country vs regional/global; data allowances; durations; top-ups.Tethering: Hotspot/hotspot limits; restrictions that can trip you up.Transparency: Clear fair-use and throttling; no surprise overages.App and support: Installation, diagnostics, 24/7 help, offline instructions.Price per GB: Value relative to local prepaid and other eSIMs (not just headline “unlimited”).Quick verdictSimology: Best overall for reliability and multi-country trips thanks to multi‑network switching and strong regional bundles. Great balance of speed, flexibility, and support.Airalo: Best for bargain hunters on single-country light/medium data, if you’re okay with typically using one local network per country.Holafly: Best for simple “unlimited”-style plans if you accept fair‑use throttling and hotspot caveats; ideal for heavy daily social/maps use.Nomad: Strong all-rounder with flexible plan sizes and a good app; coverage varies by destination, often single-network per country.Jump to regions: Esim Western Europe | Esim North America | Esim United States | Esim France | Esim Italy | Esim SpainDeep dive: Simology vs Airalo vs Holafly vs NomadSimology — multi‑network reliability and regional freedomWhat stands out - Multi‑network switching in many countries: your eSIM connects to more than one local carrier and can move when signal or capacity drops. This is crucial in rural areas, basements, stadiums, and busy city centres. - 4G/5G where available, with clear fair‑use terms. Hotspot/tethering supported on most plans. - Regional passes that “just work” across borders (great for train trips and road trips).

Review destination notes for 5G and hotspot support.Which plan should you pick? Real-world scenariosOne country, light data (maps, messages, rides)Airalo or Nomad can be the cheapest route if you’re mostly urban and don’t need redundancy.Prefer reliability across cities and countryside? Choose Simology’s single‑country options, e.g. Esim United States or Esim France, for multi‑network coverage where available.Two to six countries in Europe (train trips, road trips)Use a regional pass to avoid juggling eSIMs. Simology’s Esim Western Europe keeps service live as you cross borders, with multi‑network switching in many countries including Esim Italy and Esim Spain.Heavy user who prefers “unlimited”? Holafly’s Europe options may fit, if you’re fine with fair‑use throttling and potential hotspot limits.US/Canada/Mexico loop or North America business travelGo regional. Simology’s Esim North America covers typical NA routes with multi‑network redundancy in key areas.If visiting only one country and mainly urban, a low‑cost Airalo/Nomad plan may suffice for light users.Remote work and tetheringPrioritise providers that allow hotspot and offer redundancy. Simology plans generally include tethering and multi‑network switching for steadier connections during calls and uploads.Avoid “unlimited” plans where hotspot is restricted if you must tether.Teams and frequent flyersCentralise purchasing and support with Simology For Business and manage destinations across staff via the portal. If you run a travel brand or community, see our Partner Hub.Setup checklist: get it right first timeBefore you fly 1. Check device compatibility: your phone must be eSIM‑capable and network‑unlocked. 2. Pick the right scope: single-country vs regional. If crossing borders, a regional pass reduces admin. 3. Download the provider app on Wi‑Fi; have your QR or installation instructions offline (screenshots work). 4. Know the APN: most eSIMs auto‑configure; if not, note the APN from your plan page. 5. Decide your line settings: keep your physical SIM for calls/SMS if needed; set the eSIM for mobile data.On arrival 1. Toggle on the eSIM line and enable Data Roaming for that line. 2. Set the eSIM as your Mobile Data line (and default for iMessage/FaceTime if desired). 3. Check you’re on 4G/5G. If speeds seem off, toggle airplane mode or manually reselect a network. 4. If prompted, add the APN and restart your device. 5. Test maps/web; then enable hotspot if you plan to tether.Pro tips - Save your boarding pass and eSIM QR offline; airport Wi‑Fi can be patchy. - If you rely on ride‑hailing on arrival, pre-install and test your eSIM before take‑off. - In weak-signal areas, providers with multi‑network switching (e.g., Simology) reduce dead zones and congestion pain. - “Unlimited” isn’t infinite speed: fair‑use can slow you at peak times. If you must upload large files, schedule off‑peak or use Wi‑Fi.Why multi‑network switching mattersFewer dead spots: If Carrier A has a weak cell in a rural valley or crowded station, your eSIM can move to Carrier B.Smoother 5G handoffs: Access to multiple 5G footprints increases the chance of staying on high‑speed data.Real reliability for business use: Hotspotting on calls or pushing large files benefits from redundant routes.Simology prioritises this capability in many destinations and regional bundles, which is why it leads our 2025 pick for the best eSIM for international travel.FAQsWhich eSIM is best for multi‑country trips?Simology’s regional passes like Esim Western Europe and Esim North America are designed for border‑hopping with multi‑network reliability. If you prefer “unlimited”, compare with Holafly but check hotspot and fair‑use details.Is “unlimited data” truly unlimited?Typically not. Most “unlimited” plans apply fair‑use policies that may throttle speeds after sustained heavy use. If you need consistently fast data, consider a high‑allowance metered plan instead of relying on “unlimited.”Will I get 5G everywhere?5G availability depends on the local networks and the plan. Many destinations offer 5G in major cities, with 4G elsewhere. Simology exposes 5G where partners support it; check your specific country page via Destinations.Can I use my phone as a hotspot?Often yes, but not always. Simology plans generally support tethering. Some unlimited‑style plans (e.g., certain Holafly destinations) may restrict it. Check your plan’s terms before relying on hotspot for work.Do I need to complete identity checks (eKYC)?Some countries require ID for mobile service. Many tourist eSIMs avoid this, but regulations can change. If eKYC is required, your provider will prompt you in‑app with simple steps.What if my phone is locked?Network‑locked phones can’t use most travel eSIMs. Contact your carrier to unlock before you fly. You can still use Wi‑Fi only, but mobile data via eSIM requires an unlocked device.The bottom lineIf you want the best eSIM for international travel in 2025, prioritise multi‑network switching, regional coverage, clear hotspot rules, and transparent fair‑use. Simology leads on reliability and cross‑border simplicity, with straightforward options for single countries like the Esim United States and Europe staples (Esim France, Esim Italy, Esim Spain), plus regional passes across Esim Western Europe and Esim North America.Next step: Compare plans and coverage for your route via our Destinations.
