Set Up eSIM on Samsung Galaxy S24/S25: Step-by-Step + Dual SIM Tips

Travellers love Samsung’s S-series for good reason: excellent radios, robust Dual SIM, and a clean SIM manager in One UI. If you’re switching to a travel eSIM, this guide walks you through samsung esim setup on the Galaxy S24 and S25 series — from scanning your QR code to enabling 5G and roaming, plus practical Dual SIM tips so you can keep your home number active while using local data. We’ll use One UI terms you’ll see on-device, explain the SIM Manager screens, and include a quick troubleshooting section for the most common snags (QR code errors, “profile failed,” no data, or missing 5G). Whether you’re heading to the US, Western Europe, or hopping across North America, you’ll be set up in minutes and ready to go.

Short on time? Install over Wi‑Fi before you fly, keep your home SIM’s data roaming off, and make your new eSIM the data SIM on landing. The steps below show you exactly how.

Check your Galaxy S24/S25 is ready

Before you start, run through this fast checklist:

  • Confirm eSIM support: On your phone go to Settings > Connections > SIM manager (or SIM card manager). If you see “Add eSIM,” you’re good.
  • Ensure the device is unlocked: Carrier-locked phones may only accept the carrier’s own eSIMs. If unsure, check with your original carrier.
  • Update software: Settings > Software update > Download and install. One UI updates often improve eSIM compatibility and roaming.
  • Stable internet for installation: Use reliable Wi‑Fi. Avoid VPN during installation.
  • Battery: Aim for 30%+ or plug in.
  • Have your eSIM details ready: QR code, or the manual activation details (SM-DP+ address and Activation code) from your provider.

Pro tip: Install the eSIM at home on Wi‑Fi, but only enable data roaming when you land to avoid accidental charges.

Samsung eSIM setup: Install an eSIM on Galaxy S24/S25 (One UI)

Follow these steps on One UI (S24 ships with One UI 6.1; S25 may ship with a newer version. Labels may vary slightly by region):

  1. Open Settings.
  2. Tap Connections.
  3. Tap SIM manager (or SIM card manager).
  4. Tap Add eSIM.
  5. Choose how you’ll add it: - Scan QR code - Enter activation code - Transfer from another device (if supported by your carrier)
  6. Follow the on-screen prompts to download and install the eSIM profile.
  7. When prompted, name the line (e.g., “Travel Data”).
  8. Set your preferences when asked: - Mobile data: choose your new eSIM. - Calls and messages: keep your home SIM or choose “Ask always.”
  9. Finish and wait for activation. You’ll see a signal indicator for the new line.
  10. Restart your phone if you’re not seeing service after a minute or two.

If you don’t see “Add eSIM,” your device may be region-locked, carrier-locked, or missing an update.

Option A: Scan a QR code

  • Tap Scan QR code, grant camera access, and point at the QR code from your provider.
  • If your provider gave a QR image/PDF, you can choose “Use QR code from gallery.”
  • Confirm the download. Don’t leave the screen or lock the phone until installation completes.

Option B: Enter activation code manually

  • Tap Enter activation code.
  • Enter the SM-DP+ address and Activation code exactly as provided (case-sensitive).
  • Confirm download and wait for installation. If there’s a “confirmation code” (LPA code), enter it when prompted.

Option C: Transfer from another phone

  • Tap Transfer from another device (if available).
  • Follow the on-screen instructions. Both phones usually need to be nearby, unlocked, and on Wi‑Fi.
  • Note: Many carriers don’t allow transferring eSIMs. You may need to request a fresh eSIM instead.

Activate 5G and confirm data is working

Once your eSIM is installed, make sure mobile data and 5G are properly set:

  1. Go to Settings > Connections > SIM manager.
  2. Under Preferred SIMs, set Mobile data to your travel eSIM.
  3. Tap Mobile networks (you’ll see options per SIM).
  4. For your travel eSIM, set: - Network mode: 5G/LTE/3G/2G (auto connect), if available. - Data roaming: On (when you’re abroad).
  5. Back out, then check the status bar for 5G/4G/LTE. Open a browser to test.

If data doesn’t work immediately: - Toggle Flight mode on/off once. - Restart the device. - Check APN: Settings > Connections > Mobile networks > Access Point Names. Most eSIMs auto-configure. If not, enter the APN your provider supplied. - Turn Wi‑Fi off temporarily to test cellular data.

Pro tip: Some networks offer 5G only in select cities. You might see LTE/4G most of the time — that’s normal.

Configure Dual SIM the right way (travel-friendly)

Samsung’s Dual SIM tools are excellent for travellers. Here’s how to avoid bill shock and still receive calls/messages on your home number.

  1. Set defaults - Settings > Connections > SIM manager. - Preferred SIMs:
    • Mobile data: Travel eSIM.
    • Calls: Home SIM (or Ask always).
    • Text messages: Home SIM (or Ask always).
  2. Keep your home number reachable without using data - Keep Data roaming OFF on your home SIM: Settings > Connections > Mobile networks > select your home SIM > toggle Data roaming off. - Leave call roaming on if you want to receive calls (charges may apply from your home carrier).
  3. Control when each SIM is used - Toggle individual SIMs on/off in SIM manager. - Name your SIMs clearly (e.g., “Home UK” / “USA Data”).
  4. Switch data quickly - Settings > Connections > SIM manager > Mobile data > choose SIM. - You can also long-press the Mobile data tile in Quick Panel to jump into SIM settings.
  5. Avoid unexpected call charges - In the Phone app > Settings, enable “Ask always” for calling if offered, so you pick the SIM per call. - If calls fail while roaming, try toggling VoLTE/Wi‑Fi Calling in Settings > Connections.

Pro tip: Many messaging apps (WhatsApp, Signal, Telegram) keep your account tied to your original number even if your data comes from a different SIM — perfect for travel.

Roaming settings that actually matter

Use these toggles to stay connected abroad:

  • Data roaming: On for your travel eSIM; Off for your home SIM to avoid data charges.
  • Settings > Connections > Mobile networks > select SIM > Data roaming.
  • Network mode (the 5G toggle): Ensure 5G/LTE/3G/2G (auto connect) on your travel eSIM.
  • Settings > Connections > Mobile networks > Network mode.
  • Network operators: If you have weak signal, manually select a partner network.
  • Settings > Connections > Mobile networks > Network operators > Search networks.
  • VoLTE and Wi‑Fi Calling:
  • If calls don’t connect on a roaming network, toggle VoLTE calls and Wi‑Fi Calling on/off to test.
  • Settings > Connections > Mobile networks (VoLTE) and Settings > Connections > Wi‑Fi Calling.
  • APN:
  • If data won’t start, check Access Point Names for your travel eSIM and add the APN from your provider if it’s missing.

Pro tip: Install your eSIM before departure, but only enable Data roaming on landing. This avoids background data using your new plan early.

Troubleshooting: common eSIM issues on S24/S25

  • “Add eSIM” is missing in SIM manager
  • Update One UI, restart, and check again.
  • The phone may be carrier-locked or a regional variant without eSIM. Confirm with your seller/carrier.
  • QR code won’t scan or “This code has already been used”
  • Try “Use QR code from gallery” if the camera struggles.
  • If the code is flagged as used, contact your provider to reissue a new eSIM.
  • Profile installation failed
  • Ensure strong Wi‑Fi, turn off VPN, and keep the screen awake during download.
  • Try manual entry (SM-DP+ address + Activation code).
  • Restart and retry.
  • No data after successful install
  • Set Mobile data to the eSIM in SIM manager.
  • Enable Data roaming for the eSIM.
  • Set Network mode to 5G/LTE/3G/2G (auto).
  • Add/verify APN.
  • Toggle Flight mode or reboot.
  • 5G missing
  • Not all plans/roaming partners offer 5G in all areas; you may see LTE.
  • Ensure your plan includes 5G and you’re on a 5G-capable band with your current network.
  • Calls/SMS not working on home SIM while using eSIM data
  • In SIM manager, set Calls and Text messages to your home SIM.
  • Check roaming permissions with your home carrier and try toggling VoLTE/Wi‑Fi Calling.

Advanced reset (last resort): - Settings > General management > Reset > Reset mobile network settings. Then recheck APN and SIM preferences.

Pick the right travel plan (quick matches)

Choose a regional or country plan that fits your route:

Tip: If you’re travelling across multiple countries in one trip, regional plans simplify roaming and keep you on one profile.

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.

Saudi Arabia SIM/eSIM Registration (2025): What Travelers Need to Know

Saudi Arabia SIM/eSIM Registration (2025): What Travelers Need to Know

Saudi Arabia requires real-name registration for all mobile lines, including prepaid tourist SIMs and eSIMs. That means you’ll be asked for your ID and your line will be tied to you within the national database run by the regulator (CST). The process is straightforward if you buy at an airport kiosk or an official operator store, but it can trip up travellers who arrive late, who only try smaller convenience shops, or who expect to activate via app without local ID. This guide explains exactly where to register, the IDs you’ll need, how eSIM works for visitors, and what to expect with VoIP and messaging. We also flag common pitfalls (border number confusion, app sign-ins that require Saudi credentials, and tourist SIM limits), plus practical steps to get online quickly during Umrah/Hajj or peak events. For a broader country view and alternatives for multi-country itineraries, see our travel hub at Destinations.Quick takeRegistration is mandatory: your passport and entry “border number” (issued on arrival) are used for tourist SIM/eSIM activation.Buy at the airport or official operator stores for the smoothest experience; staff can retrieve your border number if needed.eSIM is widely available from major networks (stc, Mobily, Zain). App-only activation often requires Saudi ID—stick to in-person purchase as a visitor.Most mainstream VoIP (WhatsApp, FaceTime, Skype) generally works, but expect occasional restrictions and variable quality, especially during peak pilgrim seasons.Limits apply to how many prepaid lines a visitor can register; plan for 1–2 active lines per traveller.Who needs to register, and with what ID?You must register if you:Buy a local prepaid SIM or eSIM (tourist or standard).Activate a physical SIM picked up from a reseller, kiosk, or vending machine.Replace or reissue (SIM swap) a Saudi number.Roaming on your home SIM does not require local registration.Acceptable IDs and numbersTourists/visitors: Passport + Saudi entry “border number” (assigned at immigration). The border number is often on your visa sticker or can be looked up by staff using your passport details.GCC citizens: National ID/GCC ID is commonly accepted.Residents (iqama holders): Resident ID (iqama). App-based activations may require Absher/Nafath verification.Pro tip: If you arrived on an eVisa, your border number is generated at entry. If you don’t have it to hand, ask the store staff to retrieve it against your passport. Don’t waste time chasing it yourself.Where to register and buy a Saudi SIM/eSIMBest places (fastest and most reliable)Airport kiosks: Riyadh (RUH), Jeddah (JED), Dammam (DMM), Madinah (MED) terminals have counters for stc, Mobily, and Zain. Staff handle registration in minutes, including eSIM.Official operator stores: In major malls, high streets, and business districts. Look for stc, Mobily, Zain, Virgin Mobile, or Lebara branded stores.Pop-up booths during peak seasons: Additional counters appear during Umrah/Hajj and large events.Places to avoid (unless you must)Small convenience shops: Many can sell top-ups but not complete biometric/ID registration. You risk rejection or delays.App-only sign-up: Tourist flows are often blocked by an in-app ID check that expects Saudi credentials (residents). Use in-person activation.Pro tip: During peak pilgrim periods, airport queues build fast. If you land late, consider a quick roaming day-pass or a backup travel eSIM just for the first night.eSIM in Saudi Arabia: what visitors need to knowAvailability: stc, Mobily, and Zain all issue eSIMs at staffed points of sale. You’ll scan a QR code after ID verification.Device compatibility: iPhone XR/XS and newer, most current Google Pixel and Samsung Galaxy flagships, and select other models. Confirm before you queue.In-app eSIM: Some operator apps let you “buy and activate” — but they typically require Saudi ID for verification. Tourists should assume in-person activation is needed.Reinstalling: eSIM QR codes are usually one-time use. If you delete your eSIM, you’ll likely need to visit a store for a reissue with your ID.Checklist before you go: - Ensure your phone is unlocked. - Update iOS/Android to the latest version. - Know how to add an eSIM (Settings > Mobile/Cellular > Add eSIM). - Keep stable Wi‑Fi for the QR scan at the store (staff can help). - Bring your passport and have your entry details ready.Step-by-step: buying and registering a Saudi tourist SIM/eSIM1) Choose where to buy- Airport kiosk is fastest; otherwise, an official operator store.2) Pick your operator and plan- Ask for tourist/visitor plans (often 7–30 days, with data-first bundles). Clarify if local minutes or international minutes are included.3) Provide ID- Hand over your passport. Staff will use it and your border number to register. A fingerprint scan may be requested.4) SIM or eSIM issuance- Physical SIM: inserted and activated in-store.- eSIM: you’ll receive a QR to scan. Keep the device handy and unlocked.5) Activation and test- Staff will complete CST registration. Test data and calls before you leave the counter.6) Top-up and manage- Use official apps or USSD codes to check balance and add data. App logins may require a one-time SMS OTP; keep the line active during setup.Pro tip: Ask the agent to label your number and plan details on the receipt (or take a photo of the POS screen). It helps with top-ups and support later.What it costs (typical ranges)Tourist eSIM/SIM plans commonly bundle 5–50+ GB with local minutes for 7–30 days. Larger packages add unlimited social data or international minutes. Prices are competitive with other Gulf markets, with good 4G and expanding 5G coverage in cities and pilgrimage routes.SIM card/eSIM issuance may carry a small fee; tourist packages sometimes include it.Note: We avoid listing exact prices because they change frequently and vary by channel (airport promo vs city store). Airport deals are often the most transparent for visitors.VoIP, messaging, and calling in Saudi ArabiaVoIP apps: WhatsApp, FaceTime, Skype and similar services generally work for messaging and calls, though periodic disruptions or quality variance can occur.Wi‑Fi Calling: Support depends on your home carrier and the Saudi network. It may be blocked or inconsistent for foreign numbers.Business conferencing: Most platforms (Zoom, Teams, Meet) work. Corporate VPNs can improve stability but check your company policy and local rules before use.Local voice calls: Good to have if you need to speak to hotels, drivers, or local services who prefer a Saudi number.Pro tip: If voice call quality dips during crowded events or in dense pilgrim zones, switch to text or try another VoIP app. Late evenings and early mornings are usually less congested.Common pitfalls (and how to avoid them)“No Saudi ID” app wall: As a tourist, skip app-only purchases. Go to a staffed kiosk/store for manual registration with passport + border number.Border number mismatch: If your visa and entry stamp differ, let staff look up your active border number against your passport.eSIM deleted by mistake: Don’t remove your eSIM unless you’re sure you’re done. Reprovisioning usually requires returning to a store with your ID.Line limits: Visitors are typically limited to a small number of active prepaid lines (commonly up to two). Plan device sharing or hotspots accordingly.Peak season crowding: During Umrah/Hajj, buy at the airport as soon as you land to beat queues and ensure stock.Reseller issues: Avoid unbranded stalls selling pre-registered SIMs; they can be deactivated during audits.Multi-country itineraries and transit stopsIf you’re transiting or combining Saudi with other regions, consider a separate travel eSIM to cover your stopovers, then switch to a local Saudi SIM/eSIM on arrival:North America trips: See Esim North America or country-specific options like Esim United States.Western Europe or Schengen layovers: Esim Western Europe is handy; for single-country stops, see Esim France, Esim Italy, or Esim Spain.This approach keeps you connected door-to-door while keeping Saudi registration clean and local once you land.For teams, events, and corporate travelCoordinating dozens of arrivals for conferences, construction projects, or pilgrim support teams? Pre-plan device compatibility, line limits, and pickup locations:Centralise device checks (unlock status, eSIM support) and allocate SIMs by arrival wave.Use airport kiosks for fast throughput, with a backup city store for late arrivals.Keep a roster of numbers and plan end-dates to manage renewals.Explore our enterprise options at For Business. Travel partners and resellers can coordinate fulfilment via the Partner Hub.FAQ: Saudi SIM/eSIM Registration for Tourists1) Can I buy and activate a Saudi eSIM entirely online as a tourist?Usually no. Operator apps commonly require Saudi ID for digital verification. Tourists should use airport kiosks or official stores for passport-based registration and eSIM issuance.2) What if I don’t know my border number?Staff can look it up with your passport details. It’s generated on entry and is used for SIM registration. Don’t worry if it’s not visible on your eVisa printout.3) Are there limits to how many SIMs I can register as a visitor?Yes. The regulator limits the number of prepaid lines per identity. For visitors, assume one or two lines; exact limits can vary. Plan tethering/hotspot use if you carry multiple devices.4) Do WhatsApp and FaceTime calls work in Saudi Arabia?In general, yes. Most mainstream VoIP apps work, but you may experience occasional restrictions or quality issues, especially at peak times or in crowded areas.5) Can I keep my eSIM for a future trip?If your line remains active and you don’t delete the eSIM, you may be able to recharge later. However, tourist plans often expire after 30 days, and inactive lines can be deactivated. If an eSIM is removed, you’ll likely need a new QR at a store with your ID.6) What if my phone is carrier-locked?You’ll need to unlock it before using a Saudi SIM/eSIM. Contact your home carrier in advance; unlocking in-country is rarely possible on short notice.Pro tips to finish strongKeep both SIMs active (dual-SIM/eSIM) so you can receive bank/OTP texts from home while using Saudi data.Label your Saudi line in your phone settings to avoid confusion.Take photos of the receipt, plan details, and any QR code you’re given.For hotel check-ins or ride-hailing, a local number speeds callbacks and delivery.For destination specifics, plan options, and regional coverage that pairs well with your itinerary, start at Destinations.Next step: Compare regional eSIMs for your stopovers, then plan your Saudi activation on arrival via airport kiosks. Begin with Destinations.

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 dataKeep 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.

Check costs with your operator.Set up on iPhone (dual‑SIM/eSIM)1) Install and label your eSIMSettings > 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 plan2) Assign lines for data, calls and SMSSettings > 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 stickSettings > 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 numberOpen 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 eSIMSettings > Network & Internet > SIMs (or Connections > SIM Manager) > Add eSIM.Label clearly: SIM 1 = Home, eSIM/SIM 2 = Travel.2) Assign data, calls and SMSPreferred 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 checksGoogle 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 dataConfirm 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 respondWhatsApp “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 fixesiMessage 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.

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.
