10-Day Europe Itinerary: France–Italy–Spain with One eSIM

29 Oct 2025

Planning a Europe itinerary 10 days long that hits France, Italy and Spain is absolutely doable—if you keep the route tight and the logistics simple. This guide gives you a realistic, high-speed-train-first plan from Paris to Lyon to Milan and Rome, a taste of Florence, and a finale in Barcelona. You’ll carry one regional eSIM the whole way, so your maps, tickets and translators work across borders without swapping SIMs or hunting Wi‑Fi. Expect 2–3 hours on trains most move days, one short flight at the end, and well-paced city time where it matters. We’ve included setup steps for your eSIM, the right roaming toggles, typical 4G/5G speeds by city, and pro tips to keep things moving. If you need deeper country specifics, see our France, Italy and Spain eSIM guides linked throughout.

One eSIM for three countries (Western Europe plan)

Use a single regional plan that roams seamlessly across borders. The Esim Western Europe option covers France, Italy and Spain on major networks with automatic network selection. You keep the same QR/profile the entire trip.

Suggested data allowance for 10 days: - Light user (messaging, maps, email): 5–8 GB - Moderate (social, a few video calls, city navigation): 10–15 GB - Heavy (HD streaming, frequent tethering): 20+ GB

Country-specific tips and network notes: - France: Orange, SFR, Bouygues, Free Mobile are common. See Esim France for city nuances and coverage quirks. - Italy: TIM, Vodafone, WindTre, Iliad. See Esim Italy for rail corridor coverage and 5G availability. - Spain: Movistar, Orange, Vodafone, Yoigo. See Esim Spain for Catalonia and coastal speed notes.

Typical city speeds (real-world ranges vary by street and time of day): - Paris: 4G 30–80 Mbps; 5G 120–300 Mbps - Lyon: 4G 25–70 Mbps; 5G 100–220 Mbps - Milan: 4G 35–90 Mbps; 5G 120–250 Mbps - Rome: 4G 25–70 Mbps; 5G 100–220 Mbps - Florence: 4G 20–60 Mbps; 5G 90–180 Mbps - Barcelona: 4G 35–90 Mbps; 5G 130–300 Mbps

If speeds dip indoors or in historic centres with thick stone, move closer to a window or switch networks manually (see steps below).

eSIM setup and roaming toggles (How‑to)

Follow this before you leave or on hotel Wi‑Fi on arrival.

1) Buy and install - Purchase your regional plan: Esim Western Europe. - iPhone: Settings > Mobile Data > Add eSIM > Use QR code or “Use activation code”. - Android (varies): Settings > Network & Internet > SIMs > Download a SIM > Add via QR/activation code. - Name the line “EU Data” for clarity.

2) Set data line and keep your number - Keep your physical/home SIM for calls/SMS (if needed). - Set “EU Data” as “Mobile Data” line; disable “Allow Mobile Data Switching” if you want to force data to eSIM only. - Turn OFF data roaming on your home SIM to avoid surprise charges.

3) Roaming and 5G toggles - Turn ON Data Roaming for the “EU Data” eSIM. - Preferred network: 5G Auto (iOS) / 5G preferred (Android) if your plan includes 5G; otherwise LTE/4G. - Low Data Mode/Data Saver: OFF unless you’re trying to conserve.

4) APN check - Most plans auto‑configure. If not, enter the APN provided in your eSIM email/profile. If no APN is listed, leave default; do not guess as it can block data.

5) Crossing borders - Keep the eSIM active; it will register on a local partner within 1–3 minutes. - If no data after 3–5 minutes: toggle Airplane Mode ON/OFF, then manually select a network: Settings > Mobile Network > Network Operators > choose a listed partner.

6) Tethering/hotspot - Supported on most plans; check your plan details. Enable only when needed to conserve data.

Pro tip: Download offline maps for Paris, Rome and Barcelona on Google Maps and your train e‑tickets into your wallet app before each move day.

Getting between stops: booking and seat strategy

Book high‑speed trains 2–4 weeks ahead for best fares and seat choice.
TGV (France) and Frecciarossa (Italy) require seat reservations; sit on the aisle if you plan to work, window for scenery on Lyon–Milan.
Keep e‑tickets in your wallet app and PDFs offline. Station Wi‑Fi can be busy.
For the Italy–Spain leg, a morning flight maximises day time on the ground and reduces disruption if delayed.

Data discipline that stretches your gigabytes

Download city areas on offline maps and Spotify/YouTube playlists on hotel Wi‑Fi.
Toggle low‑data mode during intercity trains when you’re just messaging.
Prefer 720p for video calls; switch off HD if your signal steps down to 4G.
Turn off background app refresh for heavy apps (social, cloud photos) on move days.

Troubleshooting on the move

No data after border crossing: Airplane Mode 10 seconds > OFF; then manually select a partner network.
Good signal bars, slow speeds: move outdoors, toggle 5G/LTE, or switch network operator.
QR lost: Most providers let you reissue from account portal/support (keep your order number).
Hotspot not working: Reboot the phone; confirm tethering is included in your plan; check APN isn’t blank.

Who this itinerary suits (and who should tweak it)

Best for: First‑timers who want flagship sights with fast intercity links and minimal airport time.
Tweak if: You dislike one‑night stops—drop Lyon or Florence and add that night to Paris or Rome.

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.

Captive portals and device limits are common.Speed: Fine for messaging and emails; variable for maps, media backups, or video calls.Security: Public Wi‑Fi is not ideal for sensitive logins without a VPN.Practical approach:Use cellular for navigation, ticket scans, ride‑hailing, and translations.Use hotel Wi‑Fi for large downloads, backups, and app updates.Keep a small data cushion for when “free Wi‑Fi” underdelivers.eSIM Strategy: Budgeting Data by Travel DayChoose a regional plan that covers your full loop to avoid SIM swaps. Esim Western Europe is the simplest option for multi-country trips like this.Typical data use (per hour): - Maps and navigation: 50–100 MB - Social/messaging with media: 50–150 MB - Web/email: 20–80 MB - Music streaming: 50–150 MB - SD video streaming: 300–700 MB (avoid on mobile data) - HD video streaming: 1.5–3 GB (avoid on mobile data) - Video calls: 300–600 MBDaily budget (realistic): - City days: 0.5–1 GB (offline maps + light sharing). - Travel days: 1–1.5 GB (tickets, live updates, platform changes, light entertainment). - Heavy cloud backup days: 1.5–3 GB (or wait for hotel Wi‑Fi).How to stay under budget (checklist): - Pre-download city areas in Google Maps/Apple Maps. - Save rail tickets/QR codes offline. - Limit auto‑backup of photos to Wi‑Fi only. - Set streaming apps to low/auto quality on mobile. - Use browser “reader mode” and disable autoplay videos.Starting in North America? Sort your device setup at home, then land ready to go. See Esim North America or Esim United States if you need coverage before your Europe flight.Dual‑SIM Setup: Keep Your Number, Use Local DataMost modern phones support dual‑SIM with one physical SIM and one eSIM (or dual eSIMs).Recommended setup (iOS and Android, similar steps): 1. Install your European eSIM (e.g., Esim Western Europe) before departure while you have stable Wi‑Fi. 2. Set the eSIM as “Mobile Data/Cellular Data.” Keep your home SIM for calls/SMS only. 3. Turn on “Data Roaming” for the eSIM. Disable roaming on your home SIM to avoid accidental charges. 4. Set “Allow Mobile Data Switching” to off to ensure only the eSIM uses data. 5. For OTPs and banking texts, leave your home SIM active for SMS. If concerned about costs, ask your provider about receiving‑SMS charges abroad.Pro tip: Add a label to each line (e.g., “Home” and “EU Data”) so the right SIM is used for voice and data.

If you book promotional fares early, point‑to‑point can beat a pass. If you value flexibility and want to change trains on the day, a pass is often worth it—just factor in Eurostar reservation fees.2) Do I need seat reservations on every leg? - No. They’re mandatory for Paris–Amsterdam Eurostar. For Amsterdam–Berlin, Berlin–Prague, and Prague–Vienna, reservations are optional but reduce stress in busy periods.3) Can I rely on station or onboard Wi‑Fi instead of mobile data? - Not reliably. Expect captive portals, time limits, and congestion. Use station/train Wi‑Fi opportunistically, but plan to have cellular data for tickets, maps, and messages.4) How much mobile data should I plan per day? - City days: 0.5–1 GB. Travel days: 1–1.5 GB. Avoid HD streaming on mobile data. A regional eSIM like Esim Western Europe keeps things simple across borders.5) Will my phone and apps work across countries without reconfiguration? - Yes with a regional eSIM. Install it once, keep it as your data line, and you’ll roam seamlessly across France, Netherlands, Germany, Czechia, and Austria.6) I’m travelling for work—any special connectivity tips? - Consider shared allowances and central billing through For Business.

Japan eSIM & Mobile Internet Guide (2025): Coverage, eKYC, Train Wi‑Fi

Planning data on the go in Japan? An eSIM is the easiest, fastest way to get online without queueing at the airport or swapping plastic cards. This 2025 traveller’s guide to “esim japan” covers what actually matters on the ground: which networks you’ll roam on, how coverage holds up on JR trains and in tunnels, typical 4G/5G speeds in real life, what Japan’s eKYC rules mean for tourists, and quick setup steps at Narita (NRT), Haneda (HND) and Kansai (KIX). You’ll also find train and station Wi‑Fi tips, hotspot/tethering notes, and a troubleshooting checklist you can use offline. If your trip spans multiple countries, we’ll show you how to combine a Japan eSIM with regional plans for a seamless itinerary. When you’re ready, browse Japan alongside other countries on Destinations.Why choose an eSIM for Japan in 2025Instant activation: Install before you fly; data works the moment you land.Keep your home number: Dual‑SIM phones let you receive calls/SMS on your primary line while using a Japan data plan.No queues or language hurdles: Skip vending machines and counter pickups.Transparent costs: Prepaid data packs, no contracts.Works across cities and rail: Good coverage along Shinkansen and most JR lines.Pro tip: Install your eSIM over reliable Wi‑Fi at home, then just toggle it on after landing. If you must install on arrival, use airport Wi‑Fi (details below).Network coverage at a glance (JR lines, cities, islands)Japan’s mobile networks are among the world’s most built‑out. Your “esim japan” plan will typically roam on one or more of these domestic carriers:NTT Docomo (broadest nationwide footprint)KDDI au (excellent suburban and rural coverage)SoftBank (strong urban performance)Rakuten (expanding; best in cities, fills gaps via roaming)What that means for travellers:Major cities: Tokyo, Osaka, Kyoto, Sapporo, Fukuoka, Nagoya and Hiroshima have near‑universal 4G with deep‑indoor coverage; 5G is widespread in dense areas.JR Shinkansen corridors:Tokaido/Sanyo (Tokyo–Osaka–Hiroshima–Fukuoka): Continuous 4G with extensive tunnel repeaters; 5G available in many sections and stations.Tohoku/Hokkaido (Tokyo–Aomori–Shin‑Hakodate): Strong coverage; some long tunnels still step down to 4G.Hokuriku (Tokyo–Kanazawa–Tsuruga): Very solid; minor dips in mountainous stretches.Local JR and private lines: Urban commuter routes have consistent service; expect brief drops in older tunnels and remote mountain valleys.Rural/coastal routes and islands: 4G is common; remote peninsulas and smaller islands may see 3G‑like speeds or short dead zones.Pro tip: If you’re riding scenic, rural lines, download offline maps and tickets before departure. Streaming music is usually fine; HD video may buffer in older tunnels.Typical speeds and performanceReal‑world expectations with a good “esim japan” plan:Urban 5G (mid‑band): 100–300 Mbps down, 10–40 Mbps up. Peak higher near outdoor 5G nodes.Urban 4G: 40–80 Mbps down, 5–20 Mbps up.Stations/Shinkansen: 20–60 Mbps down via 4G/5G repeaters; dips to 5–20 Mbps in busy carriages at rush hour.Rural: 10–30 Mbps down; uploads can be 3–10 Mbps.Latency is typically 20–40 ms in cities, 40–80 ms on trains/rural. Plenty for maps, translations, VoIP, cloud photos, and streaming at 480–720p.eKYC in Japan: what travellers need to knowJapan has strict identity rules for voice services. Here’s the traveller version:Data‑only eSIMs (no Japanese phone number): Usually no eKYC (no passport upload) required. These are ideal for tourists using apps like WhatsApp, FaceTime and LINE.eSIMs with Japanese voice/SMS numbers: Likely require eKYC (passport/ID verification) per local regulations and can take longer to activate.Domestic provider profiles: Some data plans issued by Japanese operators may still request ID to comply with carrier policy.Pro tips: - If you only need data, choose a data‑only plan to avoid paperwork. - For restaurant or courier calls to domestic numbers, use app‑based calling or ask your hotel to assist. Most bookings accept LINE or email.Train and station Wi‑Fi: what to expectShinkansen onboard Wi‑Fi: Widely available on Tokaido/Sanyo (N700 series), Tohoku, Hokuriku, and other lines. SSIDs vary (often “Shinkansen_Free_Wi‑Fi”). Speeds 2–20 Mbps depending on train occupancy; short dropouts in long tunnels.JR station Wi‑Fi: Major JR East stations offer “JR‑EAST_FREE_Wi‑Fi”; JR West and Central have similar services at key hubs. Sessions may require email/social login with 30–60 minute reconnects.Metro/private railway Wi‑Fi: Spotty; newer trains sometimes have Wi‑Fi, but it’s not guaranteed.Cafés/convenience stores: Free Wi‑Fi common at Starbucks, Tully’s, and some konbini chains.Reality check: Your eSIM’s cellular data is more stable than free Wi‑Fi when trains are crowded. Use station Wi‑Fi for large downloads; rely on cellular for everything else.Airport arrival steps (NRT, HND, KIX)Install before you fly if possible. If not, here’s a quick playbook using airport Wi‑Fi.Common steps for any airportConnect to airport Wi‑Fi (see SSIDs below).Open your eSIM installation QR/email and add the mobile plan (Settings > Mobile/Cellular > Add eSIM).Label the new line “Japan Data”.Set it as “Mobile Data/Cellular Data” line and enable Data Roaming.Keep your home line for voice/SMS if needed.APN: Most plans auto‑configure. If not provided, check your plan details and set APN manually.Toggle Airplane Mode ON/OFF once to force network registration.Test: Load a map, speed test, and your translator app.Pro tips: - If you can’t download the eSIM over public Wi‑Fi, move closer to gates or lounges for stronger signal. - Some captive portals block large downloads; tether from a companion’s phone if needed.Narita (NRT)Wi‑Fi: “Narita Free Wi‑Fi”. No password; short portal login.Strong coverage from all carriers in both terminals. Expect 4G/5G as soon as you exit immigration.Haneda (HND)Wi‑Fi: “HANEDA-FREE-WIFI”.Excellent indoor coverage; 5G present in most public areas. Ideal place to install and test before heading to the monorail/Keikyu lines.Kansai (KIX)Wi‑Fi: “FreeWi‑Fi@KIX”.Coverage is solid across T1/T2. If speeds are slow on Wi‑Fi, move towards central atriums or lounges for better throughput during busy hours.How to set up your Japan eSIM: quick How‑ToBefore departing:Check your phone is eSIM‑compatible and unlocked.Install the eSIM over home Wi‑Fi.Download offline maps for Tokyo/Kansai and your JR routes.Enable “Allow Mobile Data Switching” (iPhone) for resilience.On landing:Turn on the Japan eSIM line and Data Roaming.Confirm APN auto‑configured.Run a quick speed test; verify messaging apps.Tethering, hotspots and fair useTethering: Most “esim japan” data plans allow hotspots, but some restrict it. Check your plan details.Fair usage: High‑speed data may be subject to network management at peak times. Video may be optimised on certain networks.Battery: 5G drains faster. If you’re hotspotting on the Shinkansen, limit to 4G or use Low Power Mode.Troubleshooting checklist (use offline)No service after install: Toggle Airplane Mode; reboot; ensure Data Roaming is on; select automatic network.Stuck on 3G: Manually set 4G/5G preferred; move nearer windows in trains; disable VPN.eSIM fails to download: Switch to stronger Wi‑Fi; try again via QR; ensure date/time is automatic.Slow speeds: Test different bands by toggling 5G On/Auto; pause background cloud backups.APN missing: Enter APN from your plan; leave username/password blank unless specified.Costs and plan typesData‑only packs: Most popular for tourists. Pick by data volume (e.g., 3–20 GB) or duration (7–30 days).Unlimited‑style: Often include a daily high‑speed bucket then slower speeds. Check the daily FUP.Voice/SMS add‑ons: Require eKYC; only choose if you truly need a local number.Extensions/top‑ups: Many plans allow adding data without reinstalling the eSIM.Pro tip: Start with a conservative data allowance. Navigation, chat and light social use average 0.3–0.8 GB/day; heavy short‑video can push 1–2 GB/day.Multi‑country trips: combine Japan with regional eSIMsIf Japan is part of a longer itinerary, a regional plan can simplify things:Heading to Korea/US after Japan? Pair your Japan eSIM with Esim North America or country‑specific Esim United States.Flying on to Europe? Check Esim Western Europe or country pages such as Esim France, Esim Italy and Esim Spain.You can keep multiple eSIM profiles on modern phones and switch as you cross borders.Business and team travelNeed to equip a team for conferences in Tokyo or factory visits in Kansai? Centralise purchasing, track usage, and manage multiple lines with For Business. It’s simpler than juggling airport SIMs and receipts.Partners and resellersTravel agencies, TMCs, OTAs and content creators can deliver connectivity as part of their Japan offering. Explore commissions, assets and onboarding via the Partner Hub.FAQDo I need eKYC to use a Japan eSIM?For data‑only plans, usually not. Plans that include a Japanese phone number typically require ID verification.Will my phone work with “esim japan”?Most recent iPhones and premium Androids support eSIM and Japan’s bands. Ensure your device is unlocked and eSIM‑capable before travel.Is 5G worth it in Japan?Yes in cities: it’s widespread and fast. On trains and in rural areas, 4G remains the workhorse, so don’t worry if you only see LTE.How good is coverage on JR trains?Shinkansen lines have strong, near‑continuous coverage with tunnel repeaters. Local lines are solid in metro areas, with occasional drops in older or very remote tunnels.Can I tether my laptop on the Shinkansen?Usually yes, but check your plan’s hotspot policy. Expect 10–40 Mbps typical; enough for calls and VPN, with brief drops in long tunnels.Should I rely on free train Wi‑Fi instead of cellular?Treat it as a backup. It’s handy for large downloads at stations, but cellular is more reliable onboard and during peak times.Final pro tipsSave offline translation packs and maps for Tokyo, Kyoto and Osaka.If you need to take work calls, test your VoIP app on airport Wi‑Fi before leaving.Keep your home SIM active for banking SMS, but set “data” to the Japan eSIM.Screenshots of your QR/eSIM email help if portals block links.Next stepCompare Japan alongside other countries and get your eSIM set up before you fly via Destinations.
