Dual SIM with eSIM: Two Numbers on One Phone (Calls, OTPs, Data)

Staying reachable without burning money on roaming is the modern traveller’s headache. Dual SIM with eSIM solves it: keep your main number active for calls and OTPs, and add a low-cost local or regional data plan on the same phone. No SIM swapping. No missed texts from your bank. In this guide, we explain how dual SIM with eSIM works, how calls/SMS/data behave, and how to set it up on iPhone and Android. We also cover common use cases like work/personal separation and travel/local pairing, plus how WhatsApp and other apps handle two numbers. If you’re planning a trip, browse country and regional options via Destinations or pick ready-made bundles such as Esim Western Europe or Esim North America. For the US or single-country trips, see Esim United States, Esim France, Esim Italy and Esim Spain.

What is dual SIM with eSIM?

Dual SIM means your phone can maintain two mobile lines at once. One or both can be eSIMs (digital SIM profiles). Typical setups: - Physical SIM + eSIM active together. - Two eSIMs active (on many newer devices). - Multiple eSIM profiles stored, with up to two active at a time (device-dependent).

On dual SIM dual standby (DSDS) phones, both lines are “on” for calls and texts when idle. You set a default line for data, calls and messages, and you can switch defaults at any time.

Device support varies. Recent iPhones and most mid/high-end Android phones support dual SIM with eSIM, but some models allow only one eSIM active at a time or restrict 5G/VoLTE on the secondary line. Check your device’s specs before you travel.

Why use dual SIM eSIM? Practical use cases

Work and personal separation

  • Keep your personal number private while making and receiving work calls on a second line.
  • Set the default for outgoing calls to your work line during office hours and flip it back to personal later.
  • Mute one line at set times to reduce interruptions without missing urgent personal calls.

Travel: keep your home number for OTPs, add local data

Coverage and cost optimisation

  • Use the line with stronger coverage for data in fringe areas.
  • Keep a cheap voice/SMS plan on one line and a high-data plan on the other.
  • Switch defaults on the fly when you cross borders or move between networks.

Teams, events and short-term projects

  • Provision temporary eSIM lines for contractors, events or field staff without shipping plastic SIMs.
  • Centrally manage usage and budgets; see For Business.
  • Partners and resellers can streamline deployments via the Partner Hub.

How calls, SMS, data, OTPs and apps behave

Understanding how two lines interact avoids surprises.

  • Calls in standby: Both lines can receive calls when idle. When you place or receive a call on one line, the other may go to voicemail or show as unreachable unless your device/network supports features like call waiting across lines or Wi‑Fi Calling. Behaviour varies by carrier and phone.
  • Default for voice/SMS: You choose a default line for outgoing calls and texts, but you can select the other line per contact or per call.
  • Mobile data: Only one line provides mobile data at a time. You set this in settings. Some phones support “allow mobile data switching”, automatically using the other line if the selected data line has weak signal.
  • SMS-based OTPs: OTP texts arrive on the line tied to that number as long as that line is enabled and has signal. Data does not need to be enabled on that line. If you’re abroad, receiving OTPs may incur roaming SMS charges on your home line—turn off data roaming but keep SMS/calls enabled to control costs.
  • iMessage/FaceTime (iPhone): You can enable iMessage/FaceTime for one or both numbers and choose which to use by default.
  • WhatsApp and similar apps:
  • The standard WhatsApp app supports one number per device. Data can come from either line.
  • To run two WhatsApp accounts on one phone, use WhatsApp + WhatsApp Business (iOS/Android) or OEM dual-app features (on some Android devices).
  • Your WhatsApp number does not change just because your data comes from your travel eSIM.

Set-up: dual SIM with eSIM

iPhone step-by-step

  1. Obtain your eSIM details: QR code or activation code from your provider.
  2. On iPhone, go to Settings > Mobile Data > Add eSIM (or “Add Data Plan”).
  3. Scan the QR code or enter details. Wait for activation.
  4. Label your lines (e.g., “Personal” and “Travel”). Clear labels prevent mistakes.
  5. Choose defaults: - Default Line for Calls and SMS. - iMessage & FaceTime line. - Mobile Data line (set to your travel/local eSIM when abroad).
  6. Toggle “Data Roaming”: - Turn off for your home line while travelling. - Turn on for your travel eSIM, if required.
  7. Optional: Enable “Allow Mobile Data Switching” if you want automatic fallback.
  8. Test: Place a call from each line, send yourself an SMS from another phone, and load a webpage to confirm the data line.

Pro tips for iPhone: - You can store multiple eSIMs and swap which are active. Many newer iPhones support two active eSIMs. - Backups don’t include eSIMs. Keep your activation details safe; some carriers limit re-downloads. - For Wi‑Fi Calling, enable it separately per line (Settings > Phone > Wi‑Fi Calling).

Android step-by-step (Pixel/Samsung and similar)

  1. Get your eSIM QR/activation details from your provider.
  2. Open Settings > Network & Internet (or Connections) > SIMs > Add eSIM.
  3. Scan the QR code or enter details. Wait for activation.
  4. Name each SIM (e.g., “Work” and “Data”).
  5. Set preferences: - Preferred SIM for Calls. - Preferred SIM for SMS. - Preferred SIM for Mobile Data (set to the travel/local eSIM).
  6. Roaming: - Disable data roaming on your home line. - Enable on your travel eSIM if needed.
  7. Optional: Enable “Switch data automatically” or similar to allow fallback.
  8. Test calls, SMS, and data on both lines.

Pro tips for Android: - Some phones let you duplicate apps (Dual Messenger/App Twin) to run two WhatsApp accounts. Alternatively, use WhatsApp + WhatsApp Business. - Not all Android models support two eSIMs active simultaneously. If yours doesn’t, use one physical SIM + one eSIM, or swap active eSIM profiles as needed. - VoLTE/5G availability can differ per SIM slot/line; check your device and carriers.

Travel checklist: avoid bill shock and stay reachable

Before you fly: - Install and activate your travel eSIM over Wi‑Fi at home. - Label lines clearly and set the travel eSIM as the Mobile Data line. - Turn off Data Roaming on your home line; leave Calls and SMS on if you need OTPs. - Enable Wi‑Fi Calling for your home line if supported, to improve reachability without roaming data. - Check voicemail and call forwarding settings for both lines. - Tell your bank you’re travelling; ensure OTPs can arrive via SMS or app. - Save carrier support contacts and your eSIM activation details offline.

On arrival: - Confirm the travel eSIM connects and data works. - Place a brief test call from each line and send a test SMS. - Keep an eye on status bar icons to ensure you’re not accidentally using data on the home line.

Pro tips and common gotchas

  • Keep eSIM credentials safe: Many providers allow limited re-installs. Don’t delete an active eSIM while abroad unless you’re certain you can re-download it.
  • One data line at a time: Even with two active lines, only one provides mobile data. Choose carefully for maps, ride-hailing and tethering.
  • Call collisions: During a call on one line, the other may be unreachable on some networks. If that’s critical, enable Wi‑Fi Calling and test how your phone behaves.
  • Battery impact: Two active lines can use more battery. Mitigate by disabling 5G on the non-data line, reducing background activity, and using Wi‑Fi where possible.
  • Apps tied to a number: Services like WhatsApp, Signal and Telegram can be re-registered to another number, but you may lose message history or access. Decide which number you want long-term before switching.
  • Region-savvy plans: Multi-country eSIMs like Esim Western Europe simplify border crossings; US/Canada/Mexico travellers can look at Esim North America. Compare options by country on Destinations.

FAQs

  • Can I use both numbers at the same time?
  • Yes, both lines are on standby for calls and texts. Only one line provides mobile data at a time. If you’re on a call on one line, the other may be temporarily unreachable depending on device/network features.
  • Will OTP texts arrive while my data is on the other eSIM?
  • Yes. OTPs arrive on the line associated with that number as long as that line is enabled and has signal. Data does not need to be on for SMS. Roaming SMS fees may apply if you’re abroad on your home line.
  • Can I use WhatsApp with two numbers on one phone?
  • The standard app supports one number. To run two accounts, use WhatsApp + WhatsApp Business (works on iOS and Android) or an OEM dual-app feature on some Android phones. Your data can come from either line regardless of the WhatsApp number.
  • How do I avoid roaming charges on my home SIM?
  • Turn off Data Roaming for the home line. Keep Calls and SMS on if you need to receive OTPs or critical calls. Set your travel eSIM as the Mobile Data line. Consider Wi‑Fi Calling to improve reachability without data roaming.
  • Does dual SIM affect battery life?
  • Slightly, because the phone maintains two network registrations. Reduce impact by disabling 5G on the non-data line, using Wi‑Fi, and turning off the secondary line when not needed.
  • What if my phone supports only one eSIM active at a time?
  • Use one physical SIM plus one eSIM, or store multiple eSIM profiles and switch which is active as required. Check your device manual for limits on active lines and 5G support.

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

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

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

Apple is ideal for iPhone users prioritising privacy; DeepL is best for European language text quality; Microsoft excels in group and conversation features.Do I really need offline packs?Yes. Subways, rural areas and dense buildings can kill connectivity. Offline packs ensure you can read menus, signs and basic chats even without data.How accurate are camera translations?Live overlays are good for clear printed text, less so for stylised fonts or handwriting. Use photo/scan mode for better accuracy. Always sanity-check critical information.Is DeepL worth paying for?If you need high-quality European language text (emails, messages) and better privacy terms, DeepL Pro can be worthwhile. For casual travel use, the free tier plus Google/Microsoft camera features may suffice.Will these apps work without a local SIM?Offline packs help, but cloud results are often better. For reliable data across borders, consider a regional eSIM like Esim Western Europe or Esim North America. Country-specific options such as Esim United States are also available.Can businesses standardise on one tool?Yes. Align on privacy and glossary needs, then choose: DeepL Pro or Microsoft for documents and meetings; Google for field teams needing robust camera translations. Explore Simology’s For Business and partnership options via the Partner Hub.Final thoughtsYou don’t need the perfect translator—you need the right one for your route, language pairs and comfort level. Install two, download offline packs, and practise the presets you’ll actually use. Pair your app with dependable connectivity and you’ll handle menus, directions and chats without breaking stride.Next step: Add reliable data for your trip with Esim Western Europe to keep your translations fast and accurate across borders.

USA eSIM & Mobile Internet Guide (2025): Best Plans, Speeds, SIM Registration

Planning a trip to the United States? This guide gives you the fastest way to get connected, what speeds to expect in major cities, and how to choose the right eSIM for your itinerary. With an eSIM you can land, scan a QR code, and be online in under five minutes—no queues, no plastic SIM. The USA has three nationwide networks (AT&T, T‑Mobile and Verizon) with excellent 5G in cities and solid 4G coverage across highways. Tourist eSIMs are data‑only and don’t require passport registration; local carrier eSIMs can include a US number but often come with ID and billing hurdles. We’ll cover compatibility (including the 5G bands that matter), typical download speeds by city, and a simple airport setup checklist. If you’re visiting Canada or Mexico too, consider a regional plan to avoid border hassles. When you’re ready, pick your plan on the Esim United States page and fly with confidence.Quick take: the best eSIM for USA travel in 2025Fastest city coverage: a T‑Mobile–based plan (strong mid‑band 5G, excellent urban footprint).Balanced coverage coast‑to‑coast: AT&T or Verizon–based plans (often better on highways and in rural).Cross‑border trips (USA + Canada/Mexico): choose Esim North America.Short city breaks: 3–5 GB plans are fine for maps, rides, socials; go 10–20 GB if you stream.Long road trips: prioritise plans that include 4G/5G access across multiple bands and allow tethering.Browse all US options and durations on Esim United States. For other countries and onward routes, see Destinations.Airport setup in 5 minutes (How‑to)Do this once and you’re online before baggage claim.1) Before you fly - Buy your plan on Esim United States. - Check your phone is unlocked and eSIM‑capable. - Download the QR code or the app to your device. Some plans let you pre‑install but activate on arrival.2) On the plane (before descent) - Install the eSIM: Settings > Mobile/Cellular > Add eSIM > Use QR code/Activation code. - Label it “USA Data”. Keep your primary line for calls/SMS if needed. - Set USA eSIM as “Mobile Data” and turn “Data Roaming” ON for that eSIM. - Keep your home SIM’s Data OFF to avoid roaming charges.3) After landing - Toggle Airplane Mode OFF. Your phone should register in 30–60 seconds. - If prompted for APN, use the provider’s APN (often auto‑configured). Check the plan email. - Run a quick speed test or load a map to confirm.4) Dual‑SIM hygiene (iPhone/Android) - iMessage/FaceTime: under “Send & Receive”, keep your home number for iMessage if you rely on it. - Default line for calls: set to your home SIM if you need bank SMS; keep data on the USA eSIM.Pro tips - If data doesn’t start, toggle the USA eSIM OFF/ON, or manually select the network once. - Some tourist plans are 4G/LTE‑only; if you expect 5G, confirm before purchase. - Time‑based plans start at first network connection—avoid activating days early.Coverage, 5G bands and device compatibilityUS 5G/LTE bands that matterFor dependable 4G/5G in the USA, your device should support these bands: - 5G NR: n71 (600 MHz low‑band, T‑Mobile), n41 (2.5 GHz mid‑band, T‑Mobile), n77 (3.7–3.98 GHz C‑Band, AT&T/Verizon), and optionally n260/n261 (mmWave in dense hotspots). - 4G/LTE: Bands 2, 4/66 (AWS), 5 (850), 12/17 (700), 13 (700 Verizon), 14 (AT&T FirstNet), and 71 (600).Most recent iPhones (XR/XS and newer), Google Pixels (3 and newer) and Samsung Galaxy (S20 and newer) cover these. If you have a niche or older model, check the spec sheet for n71/n41/n77 and LTE 2/4/5/12/13/66/71.Compatibility checklistUnlocked device: required. If you bought from a carrier, confirm it’s unlocked before travel.eSIM capable: iPhone XR/XS+; Pixel 3+ (except some US carrier variants); Samsung S20+; many others.Regional variants: some China‑market iPhones lack eSIM; some budget Androids have limited band support.Dual SIM setup: assign the USA eSIM to data only; leave your home SIM for calls/SMS if needed.Hotspot/tethering: allowed on most tourist eSIMs, but some “unlimited” plans cap hotspot speeds—check plan notes.Typical speeds by city (real‑world expectations)Speeds vary by network, location, time of day and device. As a traveller using a mainstream tourist eSIM, expect roughly:New York City: 5G 150–400 Mbps down, 10–40 Mbps up; dense areas can burst higher. 4G fallback: 20–80 Mbps.Los Angeles: 5G 150–350 Mbps; 4G: 20–70 Mbps. Good mid‑band 5G in Westside, DTLA, Hollywood.San Francisco & Bay Area: 5G 120–300 Mbps; 4G: 15–60 Mbps. Coverage dips in hilly neighbourhoods and Marin.Chicago: 5G 150–300 Mbps; 4G: 20–70 Mbps. Strong city coverage, slightly slower in far suburbs.Miami: 5G 150–350 Mbps; 4G: 20–80 Mbps. Tourist zones are well served.Las Vegas: 5G 200–400+ Mbps on/near the Strip; 4G: 30–90 Mbps. Convention weeks see congestion.National Parks/Highways: often 4G or 3G‑like at 2–20 Mbps; occasional dead zones.Note: T‑Mobile typically leads for 5G speeds and availability in cities; Verizon and AT&T can edge coverage on highways and rural routes. Tourist eSIMs use one of these networks—your experience will reflect that network’s footprint.Tourist eSIM vs local carrier eSIM (what’s best for you?)Tourist eSIM (via providers like Simology) - Registration: no passport upload; email and payment only. - Phone number: usually data‑only; use WhatsApp/FaceTime/VoIP for calls. - Activation: instant via QR; install before you fly, activate on arrival. - Flexibility: buy the exact data you need; easy top‑ups. - Tethering: generally allowed, sometimes speed‑capped on “unlimited” plans.Local carrier eSIM (AT&T, T‑Mobile, Verizon stores) - Registration: may request ID and a US address; in‑store visit often required. - Phone number: yes, you get a US number for calls/SMS. - Payment: US card or cash in store; autopay may need US billing. - Plans: compelling monthly unlimited offers, but can include speed deprioritisation and store fees. - Setup: 30–60 minutes in store; useful for long stays (1–3 months+) needing a US number.Most short‑stay travellers prefer tourist eSIMs for simplicity. If you need a US number (e.g., for two‑factor SMS), a local prepaid line or a separate VoIP number can be worth it.Data allowance, pricing and planning your usageTypical traveller usage - Light (maps, messaging, ride‑hailing, email): 0.3–0.8 GB/day - Medium (socials, short videos, a few calls): 1–2 GB/day - Heavy (HD streaming, hotspots, work calls): 3–5+ GB/dayPlan sizing examples - 3–5 days in cities: 5–10 GB - 7–10 days with light hotspot: 10–20 GB - 2–3 weeks road trip: 20–40 GB (or an “unlimited” plan with fair‑use policy)Pricing benchmarks (2025, typical tourist eSIMs) - 3–5 GB: budget‑friendly, good for short breaks - 10–20 GB: best value for most travellers - Unlimited (with fair‑use): great for longer stays, but read hotspot and speed policiesSave data - Download offline maps (entire states/regions) over hotel Wi‑Fi. - Set streaming to “Auto” or SD on mobile data. - Auto‑upload photos on Wi‑Fi only.Coverage on the road and in national parksInterstates: generally solid 4G with bursts of 5G near cities/suburbs.Mountain/desert areas (Yosemite, Zion, Grand Canyon, Yellowstone): expect spotty service; carry offline maps and cached playlists.Coastal drives (Highway 1, Florida Keys): mostly covered, but some scenic stretches fade to 3G‑like speeds.Rental cars: CarPlay/Android Auto works well with eSIM data; bring a USB cable and a 12V charger.Pro tips - Share your itinerary with someone and turn on location sharing when hiking. - Download trail maps (AllTrails, National Park Service) before entry gates. - If you rely on rideshare at airports, step outside to open‑air areas—mmWave 5G inside terminals can be patchy; 4G/low‑band is more reliable.Troubleshooting and pro tipsCommon fixes - No data on arrival: toggle Airplane Mode; ensure “Data Roaming” is ON for the USA eSIM; reset network settings only as a last resort. - Slow speeds: move to open space; force 4G/LTE if 5G is congested; try a different server for speed tests. - APN missing: add the APN from your plan confirmation; most install automatically. - iMessage/WhatsApp: both continue to use your existing number; no need to re‑register unless you changed SIM priority. - Battery drain: 5G can use more power; enable Low Power Mode on long days; carry a 10,000 mAh power bank.Dual‑SIM best practice - Home SIM: Calls/SMS ON (if needed), Data OFF. - USA eSIM: Data ON, Data Roaming ON, 5G Auto/On (if included in plan).Alternatives and onward travelVisiting Canada or Mexico too?

You purchase online and activate via QR. Local carrier lines may ask for ID and a US address in store.2) Will I get a US phone number with a tourist eSIM? - Most traveller eSIMs are data‑only and do not include a US number. Use WhatsApp, FaceTime, Zoom or a VoIP app. If you need SMS for banks, keep your home SIM active for texts or consider a local prepaid line.3) Is 5G included on USA eSIM plans? - Many plans include 5G where available; some are LTE‑only. Check the plan details before purchase. Your phone must support US 5G bands (n71/n41/n77) to benefit.4) Can I use hotspot/tethering? - Generally yes, but some “unlimited” plans cap hotspot speeds or data. If you intend to work from your laptop, pick a plan that explicitly allows tethering.5) What speeds should I expect? - In major cities, 5G downloads of 150–350 Mbps are common, with 4G around 20–80 Mbps. Rural areas can be much slower. Results vary by network and congestion.6) My phone is carrier‑locked—can I still use an eSIM? - No. Your device must be network‑unlocked to use a third‑party eSIM. Contact your carrier to unlock before you fly.Next step: choose your data size and get your QR in minutes on the Esim United States page.
