Keep WhatsApp & iMessage While Using a Data eSIM Abroad

30 Oct 2025

Travelling with a local data eSIM is the cheapest way to stay online. The worry: losing your WhatsApp or iMessage identity, missing OTPs, or triggering costly SMS activations. The good news is you can keep your home phone number on WhatsApp and iMessage while using a travel eSIM purely for data. The trick is line assignment: leave your home line for calls/SMS, set the eSIM as your data line, and avoid unnecessary reactivation prompts.

This guide shows you exactly how to do it on iPhone and Android, with step-by-step settings, what to tap when apps say “SIM changed”, and how to prepare backup codes so you’re never locked out. You’ll also find dual‑SIM examples for common trips and a quick troubleshooting section. If you’re heading to the US, Europe or beyond, pick an eSIM from Destinations and follow this playbook to keep your number, cut roaming costs, and stay reachable.

The simple rule: keep your number, switch your data

Keep your home SIM/eSIM active for calls and SMS (don’t remove it unless you’re certain you won’t need OTPs or calls).
Add a travel eSIM and assign it as the “Mobile Data”/“Preferred data” line.
Turn off data roaming on your home line to prevent surprise charges.
WhatsApp and iMessage will continue to use your home number over the travel eSIM’s internet connection.

Why this works: - WhatsApp is tied to the number you registered with, not the SIM providing data. As long as the app stays logged in and your device has internet, your WhatsApp identity stays the same. - iMessage and FaceTime can send/receive via your phone number and/or Apple ID email. Once activated on your number, iMessage continues to work over any internet connection.

Pre‑trip checklist (10 minutes now, hours saved later)

Confirm your phone is unlocked and supports eSIM/dual‑SIM.
Install critical updates for iOS/Android, WhatsApp, and Messages before you go.
Activate iMessage/FaceTime on your home number while still at home. Do not toggle iMessage off/on while abroad (it can trigger a paid international SMS).
WhatsApp:
Confirm you’re registered on your home number.
Enable two‑step verification and set your 6‑digit PIN with a recovery email.
Trigger a fresh chat backup (iCloud on iPhone, Google Drive on Android).
Two‑factor authentication:
Add an extra trusted number to your Apple ID, and note how to “Get Verification Code” from Settings offline.
For Android/Google services, generate and print/save your Google backup codes offline.
Add recovery methods for banks and key apps that send OTPs.
Decide your eSIM plan: single‑country or regional.
US trip: see Esim United States.
Western Europe: see Esim Western Europe or country packs like Esim France, Esim Italy, Esim Spain.
Multi‑country across US/Canada/Mexico: Esim North America.
Save your eSIM QR/activation details offline (PDF/screenshot in a secure note).
Label your lines clearly in your phone (Home vs Travel) to avoid slip‑ups.

Pro tip: Keep mobile data off on your home line. SMS usually works without data; you’ll still receive OTPs if your home number has roaming enabled for SMS. Check costs with your operator.

Set up on iPhone (dual‑SIM/eSIM)

1) Install and label your eSIM

Settings > Mobile Service (or Cellular) > Add eSIM.
Scan your eSIM QR or use the provider app.
When asked to label, name them clearly: - Primary or Home = your home number - Travel = your eSIM data plan

2) Assign lines for data, calls and SMS

Settings > Mobile Service: - Default Voice Line: Primary/Home (so your calls show your home number). - iMessage & FaceTime Line: Choose Primary/Home.
Mobile Data: - Set Mobile Data = Travel (eSIM). - Turn off Allow Mobile Data Switching (keeps data strictly on the eSIM).
For the Primary/Home line: - Turn off Data Roaming. - Leave the line enabled so SMS and calls can reach you.

Pro tip: For contacts who must always use your home number, set their per‑contact “Preferred Line” to Primary in the Contacts app.

3) iMessage and FaceTime settings that stick

Settings > Messages: - iMessage: ON (already activated on your home number before travel). - Send & Receive: Tick your phone number and Apple ID email. Set “Start New Conversations From” to your phone number if you want continuity, or your Apple ID email if your number can’t activate while abroad.
Settings > FaceTime: - Tick your phone number and Apple ID. Ensure your home number is active here too.

Avoid toggling iMessage or FaceTime OFF/ON while abroad. It can trigger a fresh activation SMS charged at international rates by your carrier.

4) WhatsApp: keep the same number

Open WhatsApp > Settings > Account > Two‑step verification: ensure it’s ON.
Do not use “Change Number” unless you are permanently changing numbers.
If WhatsApp shows “Did you change your number?” after it detects a SIM change, tap “No”.
If asked to re‑verify, only proceed if you can receive the SMS/voice call to your home number. Otherwise, force‑quit and reopen when you have signal for your home line or Wi‑Fi Calling.

Pro tip: Link WhatsApp Web/Companion on your laptop or tablet before you fly so you can keep chatting even if your phone is briefly offline.

Set up on Android (dual‑SIM/eSIM)

Android menus vary by brand, but the flow is similar.

1) Install and label your eSIM

Settings > Network & Internet > SIMs (or Connections > SIM Manager) > Add eSIM.
Label clearly: SIM 1 = Home, eSIM/SIM 2 = Travel.

2) Assign data, calls and SMS

Preferred SIM for:
Mobile data: Travel.
Calls: Home.
SMS: Home.
Turn off Data Roaming on the Home SIM.
Keep the Home SIM enabled so you can receive SMS/OTP.

Pro tip: Some Android phones let you choose SIM per contact in the dialler/Contacts. Set important contacts to always use your Home line.

3) Messages, RCS and Google account sanity checks

Google Messages (RCS chat features) may try to verify your number via SMS when re‑enabled. If prompted abroad, choose “Not now” to avoid a charge, or connect to Wi‑Fi with the Home SIM able to send one activation SMS.
Generate and save Google backup codes before you go, and add a recovery email/phone.

4) WhatsApp: same number, new data

Confirm WhatsApp is registered to your Home number.
Keep two‑step verification ON with your 6‑digit PIN.
If you see a SIM‑change prompt, choose “No” unless you’re truly changing numbers.
Re‑verification requires SMS/voice to your Home number; do this only when you have coverage and are comfortable with any roaming SMS cost.

Common prompts and how to respond

WhatsApp “Change number?” detected:
Choose “No”. You’re only using a different data connection, not changing identity.
iMessage wants to reactivate:
Don’t toggle iMessage/FaceTime while abroad.
If it deactivates unexpectedly, you can temporarily use your Apple ID email for send/receive, or reactivate knowing one international SMS may be charged by your carrier.
Google Messages RCS activation:
Select “Not now” and activate later on Wi‑Fi, or accept that one SMS may be sent.
SIM change notifications:
These are informational. As long as you don’t re‑register WhatsApp with a new number, your account stays tied to your Home number.

Pro tip: If you absolutely must remove your Home SIM, ensure every critical account has alternative 2FA (backup codes, authenticator app, recovery contacts) and that iMessage is set to send/receive via your Apple ID email.

Troubleshooting quick fixes

iMessage shows email instead of number:
Settings > Messages > Send & Receive: select your phone number. If it won’t tick, your Home line may lack coverage for activation. Use your Apple ID email temporarily and try activation later when the Home line has signal.
Not receiving WhatsApp codes:
Ensure the Home line is enabled and can receive SMS. Try voice call verification. If you can’t get the code, use WhatsApp Web on a linked device to stay connected until you can re‑verify.
Calls/SMS going out on the wrong line:
iPhone: Edit contact > Preferred Line, or long‑press the SIM label on the call screen.
Android: Set default SIM in the dialler or choose per call/SMS if prompted.
Data still draining on Home SIM:
iPhone: Settings > Mobile Data > turn off “Allow Mobile Data Switching”.
Android: Ensure Preferred Data SIM = Travel and Data Roaming is off on Home.
Can’t install eSIM:
Confirm your phone is carrier‑unlocked and eSIM‑capable. Reboot and retry. If travelling to the US, check compatibility with Esim United States guidance; for Europe, see Esim Western Europe.

Real‑world setups

One country, maximum simplicity:
Example: Weekend in Paris. Install a France data plan, set it as Mobile Data, keep your UK SIM for calls/SMS only. See Esim France.
Multi‑city Euro trip:
Example: Italy–Spain–France in one week. Use a regional plan so you don’t juggle multiple profiles. See Esim Western Europe or country packs like Esim Italy and Esim Spain.
North America loop:
Example: US and Canada. Use Esim North America and keep your home line for OTPs and inbound calls. If only the US, see Esim United States.
Business travellers:
Centralise policy and support so staff don’t toggle iMessage abroad or re‑register WhatsApp. Volume options are available For Business, and partners can access enablement via the Partner Hub.

FAQ

Will people still see my usual number on WhatsApp?
Yes. WhatsApp identity stays tied to the number you registered. Using a travel eSIM only changes your data connection, not your WhatsApp number.
Do I need to use “Change Number” in WhatsApp when I travel?
No. Only use “Change Number” if you are permanently moving to a new number. For travel, keep your existing registration.
Can I remove my home SIM entirely?
You can, but you may lose access to SMS/OTP and iMessage number activation. It’s safer to keep the home line inserted and disable its data roaming. If you must remove it, set up backup codes, an authenticator app, and Apple/Google recovery options first.
Will iMessage charge me abroad?
iMessage itself uses data. However, (re)activating iMessage on a phone number can send one international SMS charged by your carrier. Activate before departure and avoid toggling while abroad.
Can I still receive SMS/OTP if data roaming is off on my home SIM?
Usually yes; SMS does not require data. Whether receiving SMS while roaming is charged depends on your carrier. Check your plan before you go.
WhatsApp asked me to verify again – what now?
Proceed only if your home number can receive the SMS/voice code. If not, wait until you have coverage or Wi‑Fi Calling, or use linked devices temporarily. Ensure two‑step verification is enabled to protect against SIM‑swap attacks.

Next step: Choose your travel eSIM and stay connected without losing your number. Start with Destinations.

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

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

India SIM/eSIM Registration for Tourists: KYC, Documents & Time Limits (2025)

Planning to get connected in India? Here’s the truth about tourist SIM registration in 2025: you’ll need to complete KYC (Know Your Customer) before any local SIM or eSIM works. That means showing specific documents, filling a short form, and waiting for activation. The process is straightforward once you know where to go and what to bring, but it can catch travellers out—especially if you arrive late at night or try to buy from a small corner shop. This guide lays out the documents you need, how long activation takes, typical validity limits, and whether airport counters or city stores make more sense. Searching for india sim registration tourist info? Here’s the 2025 reality, in plain English, with step‑by‑steps and pro tips so you don’t burn your first day chasing a signal.If India is one stop on a longer trip, you can also plan ahead using Simology’s regional coverage pages via Destinations.The short version: what KYC in India involvesKYC is mandatory for any India mobile connection (prepaid or postpaid), physical SIM or local eSIM.Foreign passport holders complete “manual KYC” at an operator store or airport counter (Aadhaar eKYC is for residents).Activation typically takes 30 minutes–4 hours after KYC submission; it can be up to 24–48 hours in some cases.Tourist connections are usually issued with limited connection validity (often up to 90 days or the visa period, whichever is shorter), plus your chosen plan validity (e.g., 28 days). Policies vary by operator and city.You’ll likely need to complete a quick tele‑verification call/SMS (commonly 59059) before full service starts.What documents you’ll need (tourist checklist)Bring originals, plus printed copies where possible:Passport (original) with photo pageValid Indian visa or e‑Visa ETA approval (printout recommended)Local Indian address: your first hotel/host address is fineRecent passport‑sized photo (not always required; many stores take a live photo)Indian arrival stamp or boarding pass (sometimes requested)Secondary contact (optional): hotel phone or a local reference if you have onePro tip: Print your e‑Visa approval and first hotel booking. Airport counters are efficient but still appreciate paper copies.Where to buy: airport counters vs city storesAirport counters (Airtel/Jio/Vi) at major hubsProsStaff handle foreigner KYC all day, every day; English usually spoken.Activation often completes in 30–120 minutes.You’ll leave connected (or very close to it) before your transfer.ConsPrices can be higher than city rates or bundled with fixed tourist packs.Counters may close late night in some airports or run short on stock.City storesProsWider choice of plans; prices can be lower.Company‑owned operator stores can extend or re‑verify connections if needed.ConsNot all small retailers are authorised to complete foreigner KYC.You may be asked to return later for activation; waits of several hours are common.Practical rule: If you need data immediately, buy at the airport. If you’re price‑sensitive and can wait, head to an official operator store in the city (Airtel/Jio/Vi “experience”/“gallery” stores, not random kiosks).Step‑by‑step: getting a local SIM or eSIM as a touristChoose your operator and outlet - Go to an airport counter or a company‑owned store in the city. - Ask for a prepaid tourist connection; confirm it will be registered on your passport/visa.Hand over documents - Show your passport and visa; provide your hotel address and a local contact if asked. - The agent scans documents and takes a live photo.Complete the CAF (Customer Acquisition Form) - You’ll sign a digital or paper form. Check your name and passport number carefully.Receive SIM or eSIM activation - Physical SIM: inserted immediately. - eSIM: you’ll get a QR code. Ensure your phone is unlocked and supports eSIM. - Keep the SIM packaging and receipt.Wait for KYC processing - Expect 30 minutes–4 hours on average. Airport purchases are usually quickest.Complete tele‑verification - You may be prompted to call 59059 or respond to an SMS to confirm your name, DOB, or ID details. - Incoming service typically starts first; outgoing/data follows after verification.Test data and calls - Restart your phone. APN settings usually auto‑configure. If not, ask staff to set them.Keep proof of purchase - Save the sales receipt and a photo of the CAF in case you need re‑verification or support.Activation timelines and time limitsActivation windowTypical: 30 minutes–4 hours after KYC submission.Worst case: up to 24–48 hours, especially for late‑night processing or manual reviews.Plan validity (prepaid pack)Common options: 28 days, 56 days, 84 days. Pick what matches your stay.Connection validity (tourist KYC)For foreign passport holders, operators often cap the connection validity to the visa period or a shorter operator policy window (commonly up to 90 days).If you extend your stay, visit an operator store for re‑KYC to keep the number active.Inactivity rulesLong periods without usage/recharge can lead to suspension and eventual number recycling. If you plan to return to India soon, keep a small balance or recharge to maintain activity.Note: Policies can vary by operator and city. Ask the agent to state both your plan validity and your connection validity at purchase.eSIM vs physical SIM in India (tourists)Local eSIM (Jio/Airtel/Vi)Requires the same in‑person KYC as a physical SIM.Good if your phone lacks a physical SIM slot.Activation usually similar speed once KYC is accepted.Physical SIMWidely available, cheap, and quick at airports.Easy to swap between devices.International travel eSIMBuy online before arrival; no Indian KYC, instant activation on landing.Connects via roaming on local networks; generally costs more per GB than a local SIM but saves time/effort.Handy buffer until you can complete local KYC—or for very short trips.Planning multi‑country travel? Explore regional coverage via Destinations. If you’re continuing beyond India, browse options like Esim Western Europe, Esim North America, and country pages such as Esim United States, Esim France, Esim Italy, and Esim Spain.Costs: what to expectSIM/eSIM issuance: Usually included in the prepaid pack price for tourists.Typical starter packs: Priced competitively; airport bundles can carry a premium versus city stores.Add‑ons: Local call/text top‑ups are inexpensive. International calling is extra—use data apps unless you specifically need voice to overseas numbers.Tip: Ask for a pack with enough high‑speed data for maps, ride‑hail, and translations (e.g., 1.5–2GB/day). Heavy streamers should choose larger data packs or flexible top‑ups.Common pitfalls (and how to avoid them)Buying from unauthorised stallsSymptom: Long activation delays or failed KYC. Solution: Use operator‑owned stores or airport counters.Missing documentsSymptom: Refusal to process tourist KYC. Solution: Carry passport, printed visa/e‑Visa, hotel address, and a passport photo.Locked phone or incompatible deviceSymptom: SIM not recognised or eSIM fails to download. Solution: Ensure your device is unlocked and supports Indian LTE bands/eSIM before travel.Skipping tele‑verificationSymptom: Incoming works, but no outgoing/data. Solution: Complete the 59059 call/SMS step promptly.APN not setSymptom: Voice/SMS works, but no data. Solution: Ask staff to configure APN or restart the device; most settings auto‑provision.Pro tips for smooth registrationBuy at the airport if you need immediate data; go to a flagship operator store in the city for lower prices or complex requests (extensions, re‑KYC).Keep a scanned copy of your passport and visa on your phone and a printed copy in your daypack.If your arrival is late at night, verify airport counter hours beforehand; consider an international eSIM as a bridge until local KYC completes.Dual‑SIM phones: Put your home SIM on secondary and keep data on the Indian SIM to avoid bill shock.Ask the agent to note your connection validity (KYC expiry) and set a reminder if your stay approaches that date.Save customer care numbers and your CAF/SIM receipt photo for any re‑verification.For organisers and retailersManaging a group or frequent trips?

India requires in‑person KYC for both physical SIMs and local eSIMs. An international travel eSIM purchased online is the only way to avoid local KYC.How long does activation really take?Commonly 30 minutes–4 hours after KYC, faster at airports. Be prepared for up to 24–48 hours in some cases.What’s the typical validity for a tourist SIM?Your plan might be 28–84 days, but the underlying connection for foreign passports is often capped to the visa period or a shorter policy window (commonly up to 90 days). Check both at purchase.Do I need a local reference or Indian phone number?Not always. A hotel address is usually sufficient. Some stores may ask for a contact number—your hotel’s main line normally works.Can I convert a tourist SIM to a long‑term plan?If you extend your stay or change your visa, visit an operator store for re‑KYC. Policies vary by operator; bring updated documents.Is airport pricing a rip‑off?It’s usually a reasonable premium for speed and convenience. If you can wait and want the lowest price, use a flagship operator store in the city.Next stepCompare your options and line up connectivity for every leg of your trip via Simology’s Destinations page.

Family Travel Data: Kids’ Phones, Parental Controls & Data Budgets

Planning a family trip is challenging enough without worrying about runaway roaming bills or kids disappearing into YouTube the minute you land. A family travel eSIM setup gives each child their own data line you can control, budget and pause on demand—while your home SIM stays safe from bill shock. In this guide, you’ll set up child lines in minutes, apply iOS and Android parental controls that actually work abroad, and put firm data budgets in place. We’ll cover roaming limits that prevent surprises, smart shared data strategies, and how to choose the right country or regional plan. Whether you’re heading to one country or crossing borders, you’ll find clear, time-saving steps and checklists. Browse regional and country options via Destinations, including multi-country passes like Esim Western Europe and Esim North America, or single-country plans such as Esim United States, Esim France, Esim Italy and Esim Spain.What a family travel eSIM setup looks likeEach child has a prepaid travel eSIM on their phone for data abroad.The home SIM stays in the phone with “Data Roaming” OFF (so the bill stays safe).The parent has an eSIM too, to test settings and share tethering in a pinch.Parental controls limit app installs, screen time, explicit content and in-app purchases.OS-level data controls cap usage, block background data and keep video from eating the bundle.This approach keeps your home numbers available for Wi‑Fi calling or messages, but all mobile data goes through a fixed-cost travel eSIM you can top up if needed.How to set up child travel eSIMs (15–30 minutes)1) Confirm device compatibility- iPhone XS/XR or newer support eSIM. For Android, check Settings > About phone or the maker’s site.- If the device is carrier-locked, it may still accept eSIM profiles from roaming partners, but many plans require an unlocked phone.

Most plans are per device; giving each child their own eSIM keeps budgets clear and controls simple.Q: Can I just share my data via hotspot from one parent phone?A: You can, but it’s hard to track usage and easy to blow through the bundle. Separate eSIMs per child make limits enforceable and reduce arguments.Q: How do I cap my child’s data?A: Use OS data warnings/limits (Android), Low Data Mode/Data Saver, and app‑level restrictions. On iPhone you can’t set a hard cap, but you can monitor usage daily and disable the line or top up when it hits your threshold.Q: Will calls and SMS work with a data‑only eSIM?A: Yes—over-the-top services like iMessage, WhatsApp, FaceTime and Wi‑Fi calling work with data. Your home SIM can still receive regular calls/SMS over Wi‑Fi with roaming off.Q: Do parental controls still work abroad?A: Yes. iOS Screen Time and Google Family Link are account‑based and apply anywhere you have data or Wi‑Fi. Set them up before travel.Q: What if my child’s phone is carrier‑locked?A: Check with your carrier about unlocking before you buy a travel eSIM. Some locked devices accept only the home carrier’s profiles, which can limit options.Next stepPlan your family travel eSIM by country or region now: browse Destinations and pick per‑child plans before you fly.
