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 take

  • Registration 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 numbers

  • Tourists/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/eSIM

Best 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 know

  • Availability: 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/eSIM

1) 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 Arabia

  • VoIP 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 stops

If 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:

This approach keeps you connected door-to-door while keeping Saudi registration clean and local once you land.

For teams, events, and corporate travel

Coordinating 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.

FAQ: Saudi SIM/eSIM Registration for Tourists

1) 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 strong

  • Keep 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.

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.

UK eSIM & Mobile Internet Guide (2025): Best Plans, 5G, Fair‑Use

UK eSIM & Mobile Internet Guide (2025): Best Plans, 5G, Fair‑Use

Planning a UK trip in 2025? An eSIM is the fastest, most reliable way to get online the moment you land at Heathrow (LHR) or Gatwick (LGW). This guide cuts through the noise: what to buy, how to activate in minutes, where 5G actually works, and fair‑use rules that can catch travellers out. UK operators have largely switched off 3G, so you’ll rely on 4G/5G for data and VoLTE for calls. With a travel eSIM, you’ll keep your home SIM for texts and banking codes while using local‑rate data for maps, ride‑hailing and streaming. If you’re also heading into Europe, there are multi‑country options that save you swapping plans at every border.Below, you’ll find best‑fit plan advice, airport steps that just work, and practical tips to avoid bill shock. When you’re ready to pick a plan, browse UK options via Destinations or choose a regional pass such as Esim Western Europe if you’ll cross into the EU.Quick take: Should you use an eSIM in the UK in 2025?It’s the fastest way to connect at LHR/LGW—no kiosks, no queues.5G is widely available in cities and major towns; 4G covers most of the country.3G is being turned off; make sure your phone supports VoLTE and eSIM.Fair‑use on “unlimited” plans often means speed caps after a threshold.Data‑only eSIMs pair well with WhatsApp/FaceTime for calls and messages.Multi‑country trips? Use Esim Western Europe instead of juggling multiple eSIMs.Pro tip: Keep your home SIM active for OTPs/SMS, but disable its data roaming to avoid accidental charges.Best UK eSIM plans for travellers in 2025Every itinerary is different, but these profiles usually fit:Long weekend (3–5 days): 3–5 GB data. Enough for maps, socials, rides and light streaming.One week: 10–15 GB. Adds headroom for navigation, video calls and hotspotting.Two weeks: 20–30 GB. Good for frequent tethering and HD streaming.A month or remote work: 40–50 GB or “unlimited” (with a fair‑use threshold). Check hotspot allowance.What to look for:5G access: Not all plans include 5G. If speeds matter, choose a plan that explicitly supports 5G.Hotspot/tethering: Allowed on most travel eSIMs, but sometimes capped. Verify in the plan details.Validity and top‑ups: Make sure the plan’s validity covers your full trip. Prefer plans that allow in‑app top‑ups.Coverage partners: UK networks vary by region (see coverage section). If you’ll be outside big cities, 4G reach matters more than peak 5G speed.Browse UK options via Destinations. If your trip includes France, Italy or Spain, compare regional coverage on Esim Western Europe or country‑specific pages such as Esim France, Esim Italy and Esim Spain.For teams, pooled data and centralised billing are available via For Business.5G, coverage and speeds: what to expectUK networks (EE, O2, Vodafone, Three) offer strong urban coverage and improving 5G outside cities.Cities and large towns: Expect reliable 5G in central London, Birmingham, Manchester, Glasgow, Edinburgh, Leeds, Bristol, Liverpool and Belfast. Typical 5G speeds range 100–300 Mbps in busy areas, often higher off‑peak.Motorways and rail: 4G is common; 5G along main corridors is growing but can fluctuate at speed and in tunnels.Rural and coastal: 4G dominates; 5G spotty but expanding. Prioritise plans with robust 4G partners.Indoors: Older buildings can attenuate signal. Wi‑Fi calling (via apps) is your friend.Technology notes for 2025:3G shutdown: Largely complete across the UK. You’ll rely on 4G/5G for data and VoLTE for voice. Data‑only eSIMs work fine for app‑based calling.2G fallback: Not relevant for data; some networks retain 2G for legacy voice. Don’t depend on it.Device support: Most recent iPhone, Google Pixel and Samsung Galaxy models support eSIM + 5G in the UK.Heathrow (LHR) and Gatwick (LGW): connect in minutesBefore you fly (5‑minute prep)Buy and install your eSIM profile while you have reliable Wi‑Fi.Name it “UK eSIM” so you can recognise it later.Turn off data roaming on your home SIM. Leave it on for calls/SMS if needed.Download offline maps for the UK area you’ll visit.Screenshot your eSIM QR and plan details in case you need to re‑install.After landing: step‑by‑stepDisable Airplane Mode once you’re clear of the jet bridge.Turn on your “UK eSIM” line and enable data roaming for that line.Set “UK eSIM” as your Mobile Data line; keep your home SIM as Calls/SMS if you need incoming texts.Wait up to 2 minutes for network registration. Move towards the concourse for better signal if needed.Open a browser to test a page. If no data: - Check APN settings in the eSIM plan instructions. - Toggle 5G Auto/4G in Mobile Data Options. - Reboot your phone.Heathrow and Gatwick provide free terminal Wi‑Fi if you need it to complete installation. Connect to the airport network, complete any quick sign‑in, then activate your eSIM.Troubleshooting at LHR/LGW“No Service” on eSIM: Ensure the eSIM is set as the data line and data roaming is on for that line only.Stuck on 3G/No 5G: With 3G being retired, you should see 4G or 5G. If not, toggle Network Selection to Automatic; try rebooting.Slow speeds in arrivals hall: Large crowds can congest cells. Walk a minute toward baggage claim or landside for a stronger signal.Pro tip: If you’re transiting straight to the EU after a UK stopover, consider a regional plan like Esim Western Europe to avoid swapping eSIMs mid‑trip.Fair‑use, throttling and roaming nuanceFair‑use policies matter in the UK, especially post‑Brexit:“Unlimited” often isn’t truly unlimited. Many plans apply a high‑speed data threshold per day or per plan. After that, speed may be throttled until the next day or until you top up.Tethering may be capped. Some plans allow hotspotting but at reduced speeds or with a separate allowance. Check the plan notes.UK vs EU roaming: The UK is outside the EU. EU operators can set their own UK roaming rules and may charge or cap usage. If you’re relying on an EU eSIM in the UK, verify UK coverage and fair‑use before you fly.Multi‑country plans: Some regional eSIMs include both UK and EU. If your route spans the UK, France, Spain or Italy, a single regional pass (e.g., Esim Western Europe) simplifies travel.Tip for business travellers: To avoid surprises across multiple users, use pooled allowances and policy controls via For Business.How to set up and manage your UK eSIMMost travellers will install via QR. If you’re already at the airport, use the terminal Wi‑Fi for a smooth setup.iPhone (iOS 16+)Settings > Mobile Data > Add eSIM.Scan QR or enter details manually.Label the plan “UK eSIM”.Set as Mobile Data line; leave your home SIM for Calls/SMS if needed.Enable Data Roaming for the “UK eSIM”.In Mobile Data Options, set Voice & Data to 5G Auto (or 4G if coverage is better).Test data; apply APN if instructed.Android (Pixel/Samsung)Settings > Network & Internet > SIMs > + Add eSIM.Use QR or activation code.Set the eSIM as the Preferred SIM for Mobile Data.Turn on Data Roaming for that eSIM.Preferred network type: 5G/4G (Auto).Add APN if required, then toggle Mobile Data off/on to register.Managing during your trip:Prioritise the eSIM for data only. Keep home SIM data off.Monitor usage in Settings and the eSIM app/portal.Need more data? Top up the same eSIM rather than installing a new one.Alternatives: physical SIM, roaming and hotspotsPhysical UK SIM: Works, but you’ll queue at a kiosk, show ID, and swap cards. eSIM is faster and keeps your number active.Roaming on your home carrier: Convenient but expensive, with strict fair‑use and daily caps in many cases.Portable hotspot/MiFi: Good for groups, but another battery to charge and carry. A phone eSIM with tethering is simpler for most.Pro tips to avoid bill shock and keep service workingTurn off data roaming on your home SIM. Only the UK eSIM should have data roaming enabled.Disable Wi‑Fi Assist/Adaptive Connectivity if it triggers unintended mobile data use when Wi‑Fi is weak.Pre‑download offline maps and playlists to reduce mobile data load.Use a browser with data saver enabled for routine browsing.Keep your eSIM QR/activation code saved offline for emergencies.For multi‑country trips, use a regional eSIM like Esim Western Europe rather than stacking single‑country plans.For US stopovers en route, compare Esim United States or wider Esim North America.Partners and travel pros: Explore co‑branded solutions and affiliate tools via the Partner Hub.Planning a multi‑country itinerary?Avoid SIM‑swapping. If your route includes the UK and EU:Single pass: Esim Western Europe covers popular EU countries with one activation.Country add‑ons: Hop over to Esim France, Esim Italy or Esim Spain if you’re staying longer in one country.Transatlantic legs: Look at Esim United States or Esim North America.FAQ: UK eSIM essentialsDo I need an unlocked phone?Yes. Your device must be carrier‑unlocked and eSIM‑capable to use a UK travel eSIM.Will I get a UK phone number?Most travel eSIMs are data‑only and do not issue a local number. Use WhatsApp, FaceTime, Telegram or a VoIP app (e.g., Skype) for calls and texts.Does 5G work with all eSIMs and phones?You need three things: a 5G‑capable phone, a plan that includes 5G, and 5G coverage where you are. If any link is missing, you’ll fall back to 4G.Is tethering/hotspot allowed?Usually yes, but some plans cap hotspot speeds or usage. Check the plan details before purchase.How’s coverage in rural areas and on trains?4G is widespread; 5G is expanding but patchier outside cities. Expect variable service in deep countryside, valleys and tunnels.Can I keep my WhatsApp with my home number?Yes. WhatsApp and similar apps are tied to your account, not your active SIM. Your home SIM can stay in the phone for SMS while your eSIM handles data.Next step: Compare UK and regional eSIM plans and pick the right fit for your trip via Destinations.

Singapore Speed Test: Changi vs CBD vs MRT Lines (Peak vs Off‑Peak)

Singapore Speed Test: Changi vs CBD vs MRT Lines (Peak vs Off‑Peak)

If you’re landing in Singapore and plan to work from the airport, the CBD, or on the move across the MRT, this singapore mobile speed test breaks down what speeds you can reliably expect at peak and off‑peak hours. We tested mobile networks and public Wi‑Fi across Changi Airport terminals, core CBD nodes (Raffles Place, Marina Bay, Orchard), and inside trains and on platforms across the East‑West, North‑South, Downtown and Circle lines. We also took hotel Wi‑Fi baselines so you can decide when to stick with the room network and when to tether.Bottom line: Singapore’s 5G holds up admirably in the open, dips during CBD lunch hour, and degrades most inside moving trains at peak. Airport Wi‑Fi is good enough for HD calls but uplink can vary. If you’re time‑sensitive (check‑ins, investor calls, collaborative docs), there’s a predictable rhythm to when and where speeds fall off—and how to work around it. The open CSV dataset for this report is included below.How we ran the singapore mobile speed testWe aimed for repeatable, traveller‑relevant results rather than lab‑only maxima.Test windows:Weekday morning peak: 08:00–09:00Weekday lunch crunch: 12:15–13:30Weekday evening peak: 18:00–19:30Off‑peak baseline: 14:00–15:00 and Sunday 11:00–12:00Locations:Changi Airport T1/T3 public areas and airside seatingCBD: Raffles Place, Marina Bay, Orchard RoadMRT: Platforms and inside moving trains on EWL, NSL, DTL, CCLHotel Wi‑Fi baselines in Orchard, Bugis and Marina BayNetworks: Major Singapore operators on 5G/4G (NSA where applicable)Devices: iPhone 15 Pro and Pixel 8 (dual device to offset device bias)Tools & metrics:Speedtest by Ookla (primary), cross‑checked with Fast.comDownload/Upload Mbps, Latency ms, Jitter ms, Packet loss %Notes on signal band, handover events, and network type (5G/4G)Test practice:3–5 runs per micro‑location and time slot; median reportedStationary and in‑motion samples for MRTVPN disabled; background sync offIf you’re planning route‑by‑route connectivity for a team, see For Business for multi‑user planning and reporting options.Headline results at a glanceReal‑world medians (rounded); your result will vary by device, crowding and radio conditions, but the pattern is consistent.Changi Airport (public seating, T1/T3)Off‑peak mobile 5G: 280–420 Mbps down / 35–70 up, 17–24 msPeak mobile 5G: 150–260 down / 25–40 up, 22–32 msAirport Wi‑Fi: 70–160 down / 10–35 up, 18–35 msCBD (Raffles/Marina/Orchard streetside)Off‑peak 5G: 350–650 down / 40–80 up, 14–22 msLunch peak: 120–300 down / 15–45 up, 20–35 ms, occasional jitter spikesMRT platforms vs in‑train (EWL/NSL/DTL/CCL)Platforms off‑peak: 120–280 down / 15–50 up, 18–28 msPlatforms peak: 60–150 down / 10–30 up, 25–45 msIn‑train off‑peak: 30–120 down / 6–25 up, 28–55 msIn‑train peak: 8–40 down / 2–12 up, 40–90 ms; 1–3% packet loss bursts in tunnelsHotel Wi‑Fi baseline (three mid‑to‑upper properties)Evenings: 45–120 down / 8–25 up, 10–25 msMornings: 80–180 down / 15–35 up, 8–18 msInterpretation: - For high‑stakes video calls, open CBD spaces off‑peak or quiet airport gates are safest. - In‑train uploads during peak are the first to collapse; pre‑upload and cache where possible.Changi Airport: what speeds to expectPeak vs off‑peak at ChangiOff‑peak: Mobile 5G typically exceeds 300 Mbps down with stable uplink above 40 Mbps. Latency stays under 25 ms. Great for syncing large files before you board.Peak (early morning bank of departures): Crowds plus reflective interiors can push medians closer to 180–220 Mbps down with uplink in the mid‑20s. Still fine for HD calls; 4K uploads will stall.Airport Wi‑Fi vs mobileAirport Wi‑Fi (“ChangiWiFi” or equivalent SSIDs) was consistently usable: 70–160 Mbps down, variable uplink (10–35 Mbps). Captive portal adds 1–2 minutes the first time.Mobile beats airport Wi‑Fi for sustained uploads and jitter control. Wi‑Fi is sufficient for streaming and browsing, and a good battery saver.Pro tips: - If you need predictable uplink (publishing Reels/Shorts), prefer mobile 5G over Wi‑Fi. - Sit away from glass facades and heavy foot traffic to reduce micro‑drops. - Download offline maps and airline apps on Wi‑Fi, then switch to mobile for calls.CBD: Raffles Place, Marina Bay, OrchardMidday “lunch crunch” vs evening12:15–13:30 sees the steepest slowdowns: medians around 150–250 Mbps down and 20–35 up, with occasional jitter spikes above 20 ms. It’s not “slow,” but it can disrupt real‑time collaboration.After 18:30, speeds rebound: 300–600 Mbps down is common, uplink 40–70 Mbps, stable latency under 20 ms.Video calls and cloud workHD video calls: Smooth across CBD except during the top 10 minutes of lunch rush around major malls/food courts where jitter spikes can introduce artefacts.Large cloud sync: Schedule outside lunch peak; enable “upload throttling” in your client to avoid retries.Traveller note: - A short walk to a less reflective side street (trees/buildings breaking line‑of‑sight) often halves jitter without reducing throughput.MRT lines: congestion and handoversThe MRT is where mobile networks are most stressed: fast cell handovers, dense riders, and tunnels.Platforms vs in‑trainPlatforms: Generally fine. Even at peak, 60–150 Mbps down with acceptable uplink. If you must send a large file, do it while waiting rather than in motion.In‑train: Off‑peak is workable for browsing and messaging; real‑time uploads can stutter during tunnel segments. Peak periods see uplink drop to single‑digits and latency spikes above 70 ms.Line‑by‑line notes: - East‑West Line (EWL): Strong platform coverage; noticeable drops between elevated sections and tunnels near city. Peak uplink weakest. - North‑South Line (NSL): Better consistency inside trains, but lunchtime around Orchard sees brief congestion bursts. - Downtown Line (DTL): Deep tunnels mean brief “dead patches” during cell handovers; recover quickly but can kill a live upload. - Circle Line (CCL): Generally steady; stadium/concert events create localised spikes.Step‑by‑step: Keep your connection usable on the MRTBefore boarding: Upload or sync on the platform; queue large tasks then.In motion: Switch video calls to audio‑only if uplink drops below 5–8 Mbps.Force 4G only (optional): If your device hunts between 5G/4G, locking to 4G can stabilise latency at the cost of top speed.Use messaging apps with offline queue (e.g., email set to send on next good connection).At interchange stations: Pause uploads during tunnel transitions to avoid retries.Pro tips: - Disable background cloud photo backup during peak rides; it starves foreground apps. - If you rely on hotspot for a laptop, limit it to the platform and switch the laptop to offline mode while in‑train.Hotel Wi‑Fi baseline: when to switchEvenings (common work hours for international travellers): 45–120 Mbps down, 8–25 up. Enough for most calls, but uplink jitter can upset screen‑sharing.Mornings: Faster and cleaner; schedule large downloads (OS updates, offline maps) before leaving the room.If your hotel Wi‑Fi sits below 10 Mbps up or shows >25 ms jitter, tether to mobile for calls.Tip: - Ask reception for a 5 GHz SSID; it’s often available but not always advertised.Dataset: open CSVWe’re publishing an open CSV so you can slice the data by line, station, hour, and network type.

If screen‑shares lag, tether.Battery and stability:If your phone hunts between 5G/4G, try locking to 4G on trains; re‑enable 5G when stationary.FAQWhat’s the single biggest connectivity risk in Singapore?Uplink during MRT peak hours. Downloads stay usable, but live uploads and calls can falter inside moving trains.Is airport Wi‑Fi good enough for work?Yes for browsing and HD calls; for heavy uploads, mobile 5G is more consistent.Should I force 4G on the MRT?If you see frequent 5G/4G switching and jitter spikes, forcing 4G can stabilise latency. Switch back to 5G when stationary.How much speed do I need for a reliable video call?Aim for 10 Mbps up and stable latency under 50 ms. Below 5 Mbps up, reduce video quality or switch to audio.Do I need a local SIM or will roaming work?Both work. A local eSIM typically gives you better value and access to full 5G mid‑band. Check our Destinations for options.How does hotel Wi‑Fi compare to mobile?Often fine in the morning; evenings see contention. If uplink jitter exceeds 25 ms or uploads crawl, tether to mobile.Planning beyond Singapore?If Singapore is one stop on a wider itinerary, you can line up regional eSIMs in advance: - North America trips: Esim United States and Esim North America - Western Europe legs: Esim France, Esim Italy, Esim Spain, or a bundled Esim Western EuropeFor teams needing guaranteed capacity windows (e.g., event crews, broadcast, or sales kick‑offs), our For Business team can help with playbooks and escalation paths.
