How to Set Up an eSIM on iPhone 15/16: Step-by-Step with Fixes

30 Oct 2025

Travelling with an iPhone 15 or 16? Good news: Apple’s eSIM experience is now fast, reliable and ideal for travellers who want local data without juggling plastic SIMs. This guide walks you through a clean, repeatable iPhone eSIM setup, including QR code install, manual activation details (SM‑DP+), carrier app installs and Quick Transfer. You’ll also find practical APN tips, a fixes section for the most common errors, and pro traveller settings so data just works the moment you land. If you hit a snag at any point, jump straight to Troubleshooting below.

If you’re still shopping for a plan, browse country and regional options on Destinations — from single-country picks like Esim United States, Esim France, Esim Italy or Esim Spain to multi-country passes like Esim Western Europe and Esim North America.

Before you start: what you need

Estimated time: 5–10 minutes
Cost: Free to install (plan cost varies)

An iPhone 15 or iPhone 16 running current iOS (Settings > General > Software Update).
Reliable Wi‑Fi (strongly recommended during activation).
Your eSIM details:
Either a QR code, or
Manual activation details: SM‑DP+ address, Activation Code, and (if provided) Confirmation Code.
If transferring from another iPhone: both phones on iOS 16+ and signed into iCloud with Bluetooth on.

Quick checks: - Remove any old VPN profiles (Settings > General > VPN & Device Management) if they may interfere. - Backup screenshots or a PDF of your QR code so you have it offline on arrival.

Compatibility note: - iPhone 15/16 models sold in the United States are eSIM‑only. International variants generally still include a physical SIM tray. All support multiple eSIMs with up to two lines active at the same time.

Step-by-step iPhone eSIM setup

You can add an eSIM in four ways. Use the method your provider supports.

Tip: If your provider instructs you to activate only after you land, you can still pre‑install the eSIM over Wi‑Fi and toggle it on later.

Option 1: Install via QR code (fastest)

Connect to Wi‑Fi.
On your iPhone: Settings > Mobile Data (Cellular) > Add eSIM.
Tap Use QR Code and point the camera at your code.
When prompted, tap Continue. If asked, choose to Add eSIM.
Wait for “Activating” to complete. This can take 1–3 minutes.
Label the line (e.g., “Japan data”).
Set as your Mobile Data line if it’s your travel plan. Keep your home line for calls/SMS if needed.
Leave Data Roaming off until you arrive, unless your plan requires activation at purchase.

If you see “Invalid QR Code” or “Plan Cannot Be Added”, see Troubleshooting.

Option 2: Enter details manually (SM‑DP+ and Activation Code)

Settings > Mobile Data > Add eSIM > Use QR Code > Enter Details Manually.
Enter: - SM‑DP+ Address: e.g., “xyz.smdp.com” (exactly as provided) - Activation Code: long string (case‑sensitive) - Confirmation Code: only if your provider lists one
Tap Next and wait for activation.
Label and assign the line for data as needed.

Tip: Typo‑sensitive. Copy/paste carefully. Double‑check dots and dashes.

Option 3: Install via carrier/app

Install your provider’s app from the App Store.
Create/log in to your account and purchase/assign the eSIM to your device.
In the app, select “Install eSIM” and follow the prompts.
When iOS prompts to add the plan, confirm and wait for activation.

Option 4: eSIM Quick Transfer (moving from your old iPhone)

Put both iPhones side by side with Bluetooth on and signed into iCloud.
On your new iPhone: Settings > Mobile Data > Add eSIM > Transfer From Nearby iPhone.
On your old iPhone, approve the transfer and choose the line.
Wait for activation on the new device and confirm the line is working.
Decide whether to keep the eSIM active on the old phone (usually off for travel).

After activation: configure for travel

These post‑install settings make the difference between “it works” and “it works every time”.

Label lines: Settings > Mobile Data > tap the new plan > Label.
Default line:
Mobile Data: choose your travel eSIM.
Voice: choose your home line if you want your usual number active.
iMessage & FaceTime: Settings > Messages/FaceTime > Send & Receive > pick the appropriate number/email.
Data Roaming: Toggle on when you land in your destination.
Network Selection: If auto fails, try manual. Settings > Mobile Data > Network Selection > turn off Automatic and choose a listed partner network.
5G/LTE: Settings > Mobile Data > Mobile Data Options > Voice & Data > try 5G Auto/On or LTE per provider guidance.
Low Data Mode: Turn off if speeds seem throttled unnecessarily.

APN and data settings (only if needed)

Most eSIMs auto‑configure APN. If data connects but webpages won’t load, set APN manually.

Go to Settings > Mobile Data > your eSIM plan > Mobile Data Network (Cellular Data Network).
Under Mobile Data (Cellular Data):
APN: enter the exact APN value provided (e.g., “internet”, “fast.t-mobile.com” — this will vary).
Username/Password: leave blank unless specified.
MMS/Personal Hotspot APNs: set only if you’ve been given values.
Return one level and reboot the iPhone if the change doesn’t apply immediately.

Pro tips: - If the APN field is missing or greyed out, your profile is locked by the carrier; contact support to push correct settings. - “Could not activate mobile data network” usually means incorrect APN or temporary network registration delay. Recheck APN and toggle Airplane Mode for 20 seconds.

Troubleshooting: top errors and fast fixes

If activation fails, work methodically. Most issues resolve in under 5 minutes.

1) “Invalid QR code” / “This code is no longer valid” - Cause: Code already redeemed, expired, or scanned incorrectly. - Fix: - Confirm you’re scanning the most recent QR from your provider. - Try Enter Details Manually (SM‑DP+, Activation Code). - Ask the provider to reissue the eSIM.

2) “Activation unsuccessful” / Stuck on “Activating” - Cause: Wi‑Fi glitch or temporary carrier server timeout. - Fix: - Force‑quit Settings, toggle Airplane Mode on for 20 seconds, then off. - Reboot iPhone. - Switch to a different Wi‑Fi or use a known‑good hotspot. - Try again after 10–15 minutes.

3) “No Service” after install - Cause: Roaming off, wrong network selected, unsupported band, or not yet in the coverage area. - Fix: - Toggle Data Roaming on (when in destination). - Settings > Mobile Data > Network Selection: try manual selection of a partner network. - Settings > Mobile Data Options > Voice & Data: switch between 5G Auto, 5G On, and LTE. - Restart the iPhone.

4) Data doesn’t work; calls/SMS do (or vice‑versa) - Cause: APN not set, wrong default data line, or plan is data‑only. - Fix: - Confirm your eSIM is selected as the Mobile Data line. - Set APN manually as provided by the carrier. - If your plan is data‑only, use OTT apps for calls/messages.

5) “Plan cannot be added” / “Unable to complete cellular plan change” - Cause: Region/IMEI/EID mismatch or unsupported device profile. - Fix: - Ensure you’re on the latest iOS. - Provide your device EID to the provider (Settings > General > About). - Ask the provider to reprovision the eSIM.

6) “Could not activate mobile data network” - Cause: APN or temporary network block. - Fix: - Reenter APN, then reboot. - Toggle Airplane Mode, then test again. - Try manual network selection.

Still stuck? Delete and reinstall the eSIM: - Settings > Mobile Data > tap the plan > Remove eSIM. Re‑add via QR/manual details. Ensure Wi‑Fi is stable during reactivation.

Managing multiple eSIMs on iPhone 15/16

Store many, use two: iPhone 15/16 can store multiple eSIMs and keep up to two lines active at once.
Switch data line quickly: Settings > Mobile Data > Mobile Data > select the plan you need.
Pause a line (don’t delete): Toggle “Turn On This Line” off to keep the profile for later.
Delete when finished: Remove eSIM to tidy your list. Keep a copy of the QR/manual details in case you need to reinstall.

Pro tips for travellers

Pre‑install on Wi‑Fi before you fly, then toggle the line on when you land.
Keep your home line on for SMS codes, but set the travel eSIM as the Mobile Data line.
Save the QR code and manual details offline (Files app/Notes) for airport re‑installs.
If speed dips in crowds, try manual network selection or switch between 5G and LTE.
Hotspot/tethering: Check your plan allows it; if not working, set the APN for Personal Hotspot if provided.

Plan your eSIM by destination

Choose a country or a multi‑country pass based on your route: - Single countries: Esim United States, Esim France, Esim Italy, Esim Spain - Multi‑country: Esim Western Europe, Esim North America

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.

Best Speed Test Apps: Ookla vs nPerf vs Fast — Test the Right Way

Stuck on a shaky hotel Wi‑Fi or puzzling over whether your eSIM is underperforming on the road? Picking the best speed test app matters—but testing methodology matters more. A single tap-and-done test can mislead you by 50% or more, depending on server distance, network congestion, and device conditions. In this guide we compare Speedtest by Ookla, nPerf, and Netflix’s Fast, and show you how to test properly: multiple runs, smart server choice, and attention to latency and jitter (the things that actually make apps feel snappy or sluggish). We also cover how to export and share results with our Lab for deeper analysis, ideal for frequent travellers and teams. Whether you’re heading to the US, Spain, or across Western Europe with an eSIM, these steps will help you get reliable, comparable numbers you can trust. Let’s find the best speed test app for your trip—and use it the right way.What a “good” speed test really measuresBefore choosing an app, align on the metrics that matter for travellers:Download speed (Mbps): Bulk transfers—app updates, file sync, media downloads.Upload speed (Mbps): Cloud photos, social posts, video calls.Latency (ms): Time to first byte; affects loading, gaming, VoIP. Lower is better.Jitter (ms): Variability in latency; high jitter makes calls “stuttery.”Consistency: Throughput stability during the test (not just the peak). More consistent means fewer buffering surprises.Packet loss (%): If available, indicates reliability issues that impact real-time apps.Context also matters: - Server distance: A nearby server flatters results; a distant server can mimic “real internet” paths. - Access type: 5G vs 4G vs Wi‑Fi; carrier aggregation and signal quality (RSRP/RSRQ) affect outcomes. - Time-of-day: Congestion typically peaks evenings and weekends. - Device limits: Older phones and throttled hotspots can cap speeds.The contenders at a glanceSpeedtest by OoklaStrengths:Massive global server network for easy local testing.Lets you pick specific servers; useful for comparing “near vs far.”Shows download, upload, ping, jitter; robust test engine and familiar UI.Limitations:Can over-represent best‑case performance if you always test to the closest server.Results cards are easy to share, but structured data export takes extra steps (see export tips below).Best for:Quick local baselines at airports, hotels, cafés.Side‑by‑side device or SIM comparisons with the same server.nPerfStrengths:Measures download, upload, latency, jitter, and often packet loss.Offers “full test” including browsing/streaming quality indicators.Route/drive tests and detailed logs—great for methodical travellers and teams.Limitations:Smaller server footprint than Ookla in some regions.UI is denser; plan 1–2 minutes to configure tests properly.Best for:Quality‑of‑Experience (QoE) insights.Road trips and cross‑border testing with detailed histories.Fast (by Netflix)Strengths:Minimalist, fast, and light on data. Great when you just need a streaming‑centric read.Focuses on sustained throughput and loaded/unloaded latency (tap “Show more info”).Limitations:Less control (no server selection), fewer metrics and no rich history.Not ideal for technical diagnostics.Best for:Quick “Will Netflix/streaming be OK?” checks.Low‑data or low‑battery situations.The best speed test app… depends on your goalNeed a realistic all‑round baseline? Start with Speedtest by Ookla (near server for best case; far server for “real‑world”).Want to assess call/stream reliability? Use nPerf for jitter, loss, and QoE, plus consistency graphs.Evaluating streaming‑readiness quickly? Fast is the fastest sanity check with a streaming bias.The truth: the best speed test app is the one you use consistently—with a solid method.Test the right way: a traveller’s methodologyFollow this step‑by‑step to get fair, comparable results across places and days.Pre‑test checklist (60 seconds)Use the same device for comparisons whenever possible.Disable VPNs, ad blockers, private DNS, and battery saver modes.Pause large downloads/updates on all devices on the network.Ensure at least 20% battery and good thermal conditions (hot phones throttle).For cellular: check you’re on the intended network (e.g., 5G vs 4G), and that data saver is off.Record your context: location, indoor/outdoor, time, network (carrier/eSIM), signal bars.Server selection and runsPick two server strategies: 1) Nearest server (best case). 2) A regional/international server 500–2,000 km away (real‑world path).Run each test three times, 30–60 seconds apart.Note the median result (not the single best). Medians smooth out random spikes.Time‑of‑day spreadRepeat your medians morning, afternoon, and evening.If roaming across borders (say, Esim Western Europe or Esim North America), capture one set per country/city.Latency and jitter focusPrioritise latency and jitter when judging call/video quality.A connection with lower speed but lower jitter can outperform a “faster” link for real‑time apps.Cross‑check with two appsDo one set on Ookla and one on nPerf, back‑to‑back, same server distance logic.Use Fast as a quick third opinion if streaming is your main concern.Pro tips: - If results vary wildly, toggle Airplane Mode for 10 seconds, then retest. - On dual‑SIM phones, force the active data line to the SIM you’re evaluating. - If hotel Wi‑Fi looks fast but feels slow, try a “far” server: high latency or jitter will reveal the culprit.Interpreting results like a proDownload/upload: Aim for a median rather than a peak. For casual travel, 20/5 Mbps is comfortable for most tasks; 50/10 Mbps reduces contention headroom issues. For 4K streaming or heavy cloud backup, more is better.Latency: Under 40 ms feels crisp; 40–80 ms is fine; >100 ms feels laggy for calls and gaming.Jitter: Under 10 ms is solid; 10–30 ms can wobble; >30 ms often causes call artefacts.Consistency: Look at the graph (nPerf) or variance across runs. Big swings suggest congestion or interference.Near vs far server: If near is good but far collapses, international routing or peering may be poor—expect some apps to feel slower than the headline speed.Exporting and sharing results with our LabContributing structured data helps us produce better travel guidance.How to capture and share: - Speedtest by Ookla: - Tap Results to view history; note server, ping, jitter, download, upload. - Use Share to save a results image, and copy details into a notes app or spreadsheet. - For longer trips, create a free account so results sync across devices, then consolidate manually. - nPerf: - Use History for detailed logs. You can share results cards per test; on Android, you can also copy detailed metrics. For drive/route tests, export the session summary where available. - Fast: - Tap Show more info to reveal latency (loaded/unloaded) and upload; take a screenshot and record the time and location.Send datasets and notes to our team via the Partner Hub if you’re a contributor, or coordinate a structured study through For Business for team travel. We cross‑reference these with our route plans on Destinations.Scenario‑based recommendationsCity‑hopping in Europe:Use Ookla near server for quick hotel checks.Use nPerf with a far server to gauge cross‑border routing while on Esim Western Europe.US road trip:Use nPerf route testing to log performance along highways with your Esim United States; confirm urban hotel Wi‑Fi with Fast at check‑in.North America multi‑country:Keep a consistent daily Ookla test across cities; use Fast to sanity‑check streaming on the go with Esim North America.City stays with strict data caps:Use Fast for minimal test overhead, then a single Ookla near‑server test for confirmation.Video‑call heavy days:Prefer nPerf results with lower latency/jitter, even if the raw speed is slightly lower.Quick decision guidePick Ookla if:You want a broad server choice and fast local baselines.Pick nPerf if:You care about jitter, packet loss, and QoE, or you’ll log routes.Pick Fast if:You need a minimal, streaming‑centric check or are conserving data/battery.Use two apps when:You’re diagnosing a problem or comparing SIMs/providers.Always:Run three tests and keep the median. Test near and far servers.Regional notes for travellersFrance/Italy/Spain:Expect dense urban 5G but mixed rural 4G. Test both near and far. Consider regional bundles like Esim France, Esim Italy, and Esim Spain if you’ll linger in one country.Western Europe:Cross‑border roaming can change routing. Log a morning/evening set in each country on Esim Western Europe.United States:Mid‑band 5G is strong in many metros; rural can dip to LTE. Test outdoors for a “radio best case” on Esim United States.North America:Canada and Mexico peering differs from the US; a far‑server check gives a better “app‑feel” forecast with Esim North America.FAQWhat’s the single best speed test app?None wins universally. Use Ookla for coverage and convenience, nPerf for quality and logging, and Fast for quick streaming‑focused checks. The right methodology matters more than the brand.How many runs should I do?Three consecutive runs per server choice (near and far). Take the median. Repeat at three times of day for a robust picture.Which server should I pick?Do both: closest server (best case) and a regional/international server (real‑world). Comparing the two reveals routing and congestion effects.Why do my results vary so much?Congestion, signal changes, device thermal limits, or background traffic. Stabilise conditions with the pre‑test checklist, then use medians rather than single peaks.Does a VPN affect tests?Yes—VPNs change routing and can cap throughput. Turn them off for baseline tests unless you’re specifically testing VPN performance.How much data does a test use?Roughly 20–200 MB per run depending on your speed and app. Fast generally uses less, Ookla and nPerf can use more on very fast links. Plan your tests accordingly when roaming.The bottom lineChoose the app that fits your goal, but win on method: same device, near and far servers, three runs, medians, and a time‑of‑day spread. Prioritise latency and jitter if you care about calls and streaming, and use two apps when diagnosing. Export or log your results, and share them with us to improve future guidance for travellers.Next step: planning a trip? Pick your region and grab an eSIM, then benchmark like a pro.

Expect clear checklists, step‑by‑steps and pro tips you can act on.You’ll also find pointers for business travellers, teams and anyone continuing onward to Europe or North America. For country‑specific eSIM options, start with Destinations. If you’re coordinating multiple drivers or vehicles, see For Business. For onward legs, we’ve included links to ready‑made regional bundles like Esim Western Europe and Esim North America, plus single‑country options when you have long layovers.Route snapshot and coverage realityA realistic loop by road looks like: - UAE → Oman (Hatta/Al Wajajah or Khatmat Malaha) → return UAE - UAE → Saudi (Ghuwaifat/Batha) → Qatar (Abu Samra) - Qatar → Saudi (Salwa) → Bahrain (King Fahd Causeway) → return Saudi - Saudi → Kuwait (Nuwaiseeb)Coverage expectations: - Urban and main highways: solid 4G/5G in all six countries; 5G common in cities. - Border zones and desert stretches: expect dead spots; signals may bounce between towers across borders. - Off‑road deserts, wadis and mountain routes: intermittent or no service; plan for offline navigation and check‑ins via scheduled messages when back online.Pro tip: - Before you go, skim operator coverage maps and save them offline. If you’re comparing eSIM options by country, browse Destinations.Your eSIM strategy for a pan‑GCC road tripYou have three workable models:1) One regional/multi‑country eSIM that includes all six GCC countries- Easiest border behaviour: same eSIM, different partner network per country.- Handover is automatic at borders; keep “Data Roaming” on for that eSIM.2) A global eSIM that covers the GCC- Often slightly pricier per GB than regional, but simplest if continuing to other regions (e.g., on to Esim Western Europe or Esim North America).3) Country‑by‑country eSIMs- Best for heavy local usage in one country (e.g., a week in Oman’s mountains).- Requires manual switching at borders; more admin, cheaper per GB.Recommended for most drivers: a regional or global eSIM as your “always‑on” data line, plus optional single‑country add‑ons for data‑intensive days in cities.Set up before departure (10–15 minutes)1) Check your phone- Unlocked and eSIM‑capable? Confirm in Settings.- Update iOS/Android to the latest version.2) Buy and install your eSIMs on Wi‑Fi- Install at home, not at the border.- Label lines clearly, e.g., “GCC Regional” and “Kuwait Local”.3) Configure mobile data settings- Set your regional/global eSIM as the “Mobile Data” line.- Turn on Data Roaming for that line.- Keep “Allow Mobile Data Switching” enabled if supported.4) Network selection- Keep on “Automatic”. If a partner network under‑performs, manually try another listed network where allowed.5) Prepare for offline: maps and essentials- Download offline areas (see “Map pre‑downloads”).- Save copies of passports, car insurance and border docs in secure offline storage.- Add key numbers to contacts: roadside assistance, embassy, local emergency numbers (999 UAE, 999/112 Saudi, 999 Qatar, 999 Oman, 999 Bahrain, 112 Kuwait).6) For onward travel- If your route continues beyond the GCC, pre‑load the right bundle (e.g., Esim Western Europe or Esim North America). Long US layover? Consider Esim United States. European city breaks? See Esim France, Esim Italy or Esim Spain.What actually happens to your eSIM at bordersExpect one of three behaviours within 1–5 minutes of crossing: - Automatic re‑attach: your eSIM drops the old tower and registers on a partner network in the new country.- Signal tug‑of‑war: your phone clings to the old network’s far‑reaching tower; speeds tank or data stops.- Registration delayed: temporary no‑service while your device negotiates a profile on the new network.Border handover checklist: 1) Approach the border with mobile data on and roaming enabled for your travel eSIM.2) After crossing, wait 2–3 minutes.3) If data stalls, toggle aeroplane mode on/off for 15 seconds.4) If still stuck, open Network Selection and switch from Automatic to a listed partner, then back to Automatic after it stabilises.5) Persisting issues? Reboot. Check APN is correctly set (often “automatic”, but your eSIM email/app shows it).6) As a last resort, briefly disable other SIMs to force the device onto the travel eSIM.Pro tips: - Keep your “voice line” on your home SIM (for receiving SMS codes) but set your travel eSIM as the data line.- Each SIM/eSIM has its own Data Roaming toggle. Verify you enabled the right one.Calling and VoIP in the GCC: what to expectVoIP restrictions exist in parts of the region and can change. Practically: - UAE and Qatar: popular consumer VoIP apps (e.g., WhatsApp calls) are often restricted. Messaging still works.- Oman: similar restrictions have applied; expect variability.- Saudi Arabia, Bahrain and Kuwait: generally more permissive, but services can fluctuate.Workable alternatives: - Regular mobile calls and SMS are reliable; ask your home operator about Wi‑Fi Calling support.- Many business platforms (e.g., Teams/Zoom) may function for meetings, but quality can vary by network and location.- For critical voice, plan a fallback: local call minutes or a PSTN dial‑in for meetings.Pro tips: - Schedule important calls when you’ll be in cities/hotels on strong Wi‑Fi or known 5G.- Test your chosen call app in the first city; don’t discover issues at 14:00 in the dunes.Desert driving connectivity tacticsExpect coverage drop‑offs on empty stretches, especially at night and in mountains/wadis.Share your live location before you lose signal; it updates when you re‑connect.Save fuel stations, tyre shops and hospitals along your corridor.Take two power sources: a high‑output car charger and a 20,000 mAh power bank.Keep a paper or offline QR copy of your hotel and destination addresses in Arabic and English.Safety tip: - Don’t rely on a single app. Have Google Maps offline areas plus an alternative (Apple Maps offline, or an OSM‑based app).Hotspot and thermal safety in Gulf heatCar cabins can exceed 50°C. Phones and hotspots will throttle or shut down if overheated.Best practice: - Mount the phone near an A/C vent; avoid direct sun.- Prefer USB‑C tethering to a laptop when parked; it’s faster, cooler and charges simultaneously.- Limit 4K streaming/uploads during midday heat; schedule heavy syncs for evenings/hotels.- If speeds yo‑yo, try locking to 4G/LTE in Settings; it often runs cooler and more consistently on highways than marginal 5G.- Keep the hotspot SSID/password simple but unique; disable “auto‑join” on passengers’ devices you don’t need online.Map pre‑downloads: don’t wait for the borderGoogle Maps (offline): 1) Tap your profile → Offline maps → Select your own map.2) Cover whole‑country rectangles: UAE, Oman, eastern Saudi, Qatar, Bahrain, Kuwait.3) Enable auto‑update on Wi‑Fi.4) Save key POIs: fuel, tyre shops, 24h groceries, embassies, border posts.Apple Maps (offline): 1) Maps → your profile picture → Offline Maps → Download New Map.2) Select city/region rectangles for each country.3) Keep mobile data use to “Wi‑Fi & Mobile Data” only if you need live traffic when online again.Also consider: - An OSM‑based app with turn‑by‑turn for remote tracks.- Save coordinates for camps/hotels in both decimal and DMS formats; paste into multiple apps in case one fails.Example 10‑day connectivity checklist (ItemList)Day 1–2: Dubai/Abu Dhabi (UAE)- Test eSIM speeds on 2–3 networks; pick the fastest.- Download UAE offline maps; save border crossing POIs.Day 3: UAE → Oman → UAE- Before leaving: confirm “Data Roaming” on.- At both borders: aeroplane‑mode toggle if data stalls.- In Oman mountains: expect dead spots; use offline navigation.Day 4–5: UAE → Saudi → Qatar- Long highway; pre‑download Saudi east‑coast map tiles.- At Abu Samra entry to Qatar: allow 3–5 minutes for network re‑attach.Day 6: Qatar → Saudi → Bahrain- King Fahd Causeway: data may flip between towers; leave it on Automatic, toggle if needed.Day 7–8: Bahrain → Saudi (east)- City work calls? Use hotel Wi‑Fi for important meetings.- Heavy uploads at night to avoid heat throttling.Day 9–10: Saudi → Kuwait- Save Nuwaiseeb border POIs and Kuwait offline map.- In Kuwait City, test 5G vs 4G for stability; lock to the better performer if needed.Extras for teams, fleets and event crewsCentral management: If you’re running multiple drivers, centralise eSIM procurement, data limits and support via For Business.Partnerships: Travel organisers and rental companies can integrate connectivity into packages via the Partner Hub.Onward legs: Group drives continuing to Europe or the US can simplify with Esim Western Europe or Esim North America.FAQ1) Will one eSIM work across all six GCC countries?- Yes, if you choose a regional or global eSIM that lists UAE, Oman, Qatar, Bahrain, Saudi Arabia and Kuwait. Otherwise, you’ll need to switch country eSIMs at borders.2) How long does handover take when crossing borders?- Typically 1–5 minutes. If data stalls beyond that, use the aeroplane‑mode toggle, then try manual network selection briefly.3) Are WhatsApp or FaceTime calls reliable in the GCC?- Messaging is fine, but consumer VoIP calls are often restricted in some countries (notably the UAE and Qatar). Plan alternatives: mobile voice minutes, Wi‑Fi Calling, or business platforms where available.4) Do I need a physical SIM as backup?- Not essential, but a physical SIM from your home operator can be useful for OTPs/SMS while keeping the eSIM for data. For heavy local usage, add a country eSIM for that leg.5) Is 5G widely available?- Yes in major cities and many highways. However, on marginal coverage stretches, 4G/LTE may be more stable and cooler to run. Switch bands if your phone overheats or speeds fluctuate.6) Can I hotspot my laptop while driving?- Only a passenger should manage devices. For stability and heat control, tether by USB‑C when parked and keep the phone near an A/C vent.Next step: Compare GCC‑ready options and plan your data by country on Destinations.
