Cruise Internet Strategy: Port-Day eSIM + Onboard Wi‑Fi Reality Check

30 Oct 2025

Cruise internet is a tale of two worlds: slow, pricey satellite Wi‑Fi at sea and fast, cheap mobile data the moment you dock. The smartest approach is a “port‑day eSIM switch” — use reliable, low‑cost mobile data in port, then fall back to the ship’s Wi‑Fi only when you truly need it at sea. This playbook explains how to plan eSIMs by port, switch safely without bill shock, keep messaging working, and use offline tools so your trip runs smoothly. Expect plain-English guidance, realistic speed expectations, and simple checklists to make it work across the Med, Caribbean, Alaska, and beyond. Whether you’re a holidaymaker looking to post photos in port or a remote worker who must stay reachable, this strategy will minimise costs, preserve battery, and keep you connected where it actually matters. You’ll also find example eSIM picks by itinerary, device settings to avoid maritime roaming traps, and pro tips to stretch every megabyte.

What “cruise internet” really is (and isn’t)

At sea: your phone cannot see land-based mobile towers. Any “mobile” network that appears is usually a maritime roaming network (e.g., “Cellular at Sea” or similar) billed at extreme pay‑per‑MB rates. Avoid these entirely.
Onboard Wi‑Fi: provided via satellite. It works ship‑wide but is shared by thousands of passengers. Think high latency (600–900 ms typical), bursty speeds, and content restrictions. Useful for messages, email, and light browsing. Streaming can be hit‑and‑miss unless you pay for a top-tier plan.
In port (or close to shore): your phone can use normal mobile networks. This is where an eSIM shines: fast LTE/5G, low cost per GB, hotspot support, and predictable performance.

Bottom line: rely on eSIM data in port; use ship Wi‑Fi at sea for essentials; keep your home SIM and maritime networks out of the loop to avoid bill shock.

The Port‑Day eSIM Strategy (high level)

Before you sail, add regional/country eSIMs tailored to your ports.
While at sea, keep your phone in Airplane Mode with Wi‑Fi on; use the ship’s Wi‑Fi sparingly.
As you dock, disable Airplane Mode, switch mobile data to your travel eSIM, and go online at local rates.
Repeat per port; download offline maps and content ahead of time to minimise live data needs.

Browse options by country or region on Destinations. For multi-country trips, look at Esim Western Europe or Esim North America. For single-country stops, check Esim Spain, Esim France, and Esim Italy. US departures or overnights? See Esim United States.

Pre‑cruise checklist: set yourself up

Map your ports and dates
Note time in port and overnight stays.
Group ports by region to decide between a regional eSIM (easier) vs per‑country eSIMs (cheaper per GB).
Check device compatibility
Confirm your phone supports eSIM and is unlocked.
Pick your eSIM plan(s)
Western Med (Spain/France/Italy): Esim Western Europe is the simple pick; or combine Esim Spain, Esim France, Esim Italy for heavy usage in one country.
Caribbean with a US stop: Esim North America plus Esim United States coverage as needed.
Install eSIM(s) before you sail
Add them to your phone and label clearly (e.g., “EU eSIM”).
Do not enable data roaming on your home SIM.
Download offline essentials (per port)
Maps (Google Maps/Apple Maps), city guides, translation packs, transit schedules, and ride‑hail apps.
Entertainment and podcasts for sea days.
Messaging readiness
Ensure WhatsApp/Telegram/Signal are installed and logged in.
If you use iMessage/FaceTime, confirm they work on Wi‑Fi only.
Payment and security
Enable offline modes for wallets where supported.
Set up VPN if your company requires it (remote workers: see For Business).

Pro tip: Create a “Cruise” Home Screen page with your travel apps and widgets (clock for home time zone, calendar, maps).

Onboard days: reality check and best use of ship Wi‑Fi

Expect high latency and variable speeds subject to congestion, weather, and ship hardware. Use it for: - Text and low‑resolution photo messaging - Email (set to manual fetch or low-frequency sync) - Essential work chat (Slack/Teams) with notifications only - Basic browsing and booking changes

Avoid: - Big OS/app updates and cloud photo backups - Video calls (unless on a premium package and off‑peak) - Streaming in HD

Workarounds: - Schedule uploads for port days. Queue photos and videos but pause sync until docked. - Use “Low Data Mode” (iOS) or “Data Saver” (Android). - Compress photos before sending; use “Less Data” options in chat apps. - Try audio‑only calls over Wi‑Fi if video stutters.

Port days: switch to eSIM and get things done fast

A simple, repeatable routine: 1. As the ship docks, wait for the “mobile signal” icon to appear. 2. Disable Airplane Mode. 3. Set Mobile Data to your travel eSIM. Keep your home SIM active for calls/SMS only if needed, but leave Data Roaming OFF on the home line. 4. If data doesn’t start, toggle Data Roaming ON for the travel eSIM and confirm APN settings provided in your eSIM install notes. 5. Turn on Personal Hotspot if you want to share with family devices (best value in port). 6. Open your to‑do list for the day: maps, transport, restaurant bookings, content uploads, backups.

Pro tips: - Offline maps per port save battery and data. Update with a quick “refresh” when you first connect in port. - If coverage is dense, let the phone choose the best local network automatically; if you see flapping, try manual network selection. - Banking and ride‑hail apps may challenge logins in new countries; keep SMS/Authenticator access handy. - Leave port with at least 30 minutes to spare for any queued cloud syncs.

Example itineraries and eSIM picks

Western Mediterranean (Barcelona–Marseille–Genoa–Rome–Naples)
Easiest: Esim Western Europe to cover Spain, France, and Italy on one plan.
Power users: Pick larger data buckets in Esim Spain, Esim France, and Esim Italy if you’ll stream or hotspot heavily in a single country.
Eastern Caribbean with Miami turn
Regional plan: Esim North America for US coverage plus supported nearby destinations.
If spending extra days in the US before/after: add Esim United States with a larger data allocation.
Alaska (Seattle/Vancouver turn with Canadian port)
Combine Esim North America for US/Canada coverage so you don’t need to swap mid‑trip.

Costs: a realistic comparison

Maritime roaming (at sea on “cellular at sea”):
Commonly charged per MB at premium rates. Even a few photos can cost more than a day of ship Wi‑Fi. Best avoided entirely.
Ship Wi‑Fi:
Day passes often priced per device, sometimes tiered (basic vs streaming). Good for light use; speeds vary.
Port‑day eSIM:
Low cost per GB, 4G/5G performance, and hotspot support included. Ideal for uploads, map/navigation, and all heavy tasks.

A practical mix: - Buy the smallest ship Wi‑Fi plan that keeps you reachable at sea. - Put your heavy data needs into port windows using eSIM. - If you travel as a family, one larger eSIM data pack with hotspot sharing in port can be excellent value.

Settings that prevent bill shock at sea

iOS (iPhone): - Settings > Mobile Data - Set “Mobile Data” line to your travel eSIM when in port; switch back to “Off” at sea. - For your home line, tap it and turn off “Data Roaming.” - Airplane Mode at sea, Wi‑Fi ON for ship Wi‑Fi. - Disable Wi‑Fi Assist (Settings > Mobile Data > Wi‑Fi Assist OFF). - Low Data Mode ON during sea days.

Android (varies by brand): - Settings > Network & Internet > SIMs - Turn OFF Data Roaming on your home SIM. - Set your travel eSIM as the “Preferred SIM for data” in port. - Airplane Mode at sea, then turn Wi‑Fi back ON. - Disable “Switch to mobile data” or “Adaptive connectivity” features that might sneak data. - Enable Data Saver on sea days.

General: - Do not connect to any “cellular at sea” network. Airplane Mode prevents accidental attachment. - Remove or pause auto‑updates and cloud backups until you’re in port.

How to juggle ship Wi‑Fi and port‑day eSIM (step‑by‑step)

The evening before a port: 1. Queue uploads (photos/video) but pause cloud sync. 2. Download offline maps and transit info for the next port. 3. List tasks you’ll complete in port (banking, large app updates, content posts).
As you dock: 1. Disable Airplane Mode. 2. Select your travel eSIM for mobile data and enable data roaming on it if required. 3. Run through your task list; hotspot to family if needed.
Departing port: 1. Finish uploads 30 minutes before sail‑away. 2. Switch back to Airplane Mode; turn Wi‑Fi ON for ship access. 3. Keep cloud backups paused until the next port.

Messaging that works everywhere

iMessage/FaceTime: run fine on ship Wi‑Fi for text and audio; video can struggle.
WhatsApp/Telegram/Signal: reliable for text and compressed media; enable “low data” options.
Wi‑Fi Calling: many carriers allow it on ship Wi‑Fi; enable in phone settings. If your carrier blocks it, use app‑based calling.

Pro tip: Tell close contacts you’re “real‑time in port, delayed at sea.” It sets expectations and reduces pressure to stay online on slow satellite links.

For teams and frequent cruisers

Remote work: If you must remain reachable, pair minimal ship Wi‑Fi with disciplined port‑day sprints for heavy tasks. Your IT team may require a VPN — set and test it before sailing. See For Business.
Travel agents and group organisers: Simplify group comms with a shared eSIM plan per cabin for port days. Explore partnerships on Partner Hub.

FAQ

Will my eSIM work at sea?
No. eSIMs use land-based mobile networks. At sea, only ship Wi‑Fi or expensive maritime roaming is available. Keep your phone in Airplane Mode at sea and use Wi‑Fi.
Can I keep WhatsApp and iMessage working without buying the top Wi‑Fi package?
Usually, yes. Texts and low‑res photos work on basic ship Wi‑Fi. For video calls or large media, wait for port and use your eSIM.
How do I avoid charges on my home SIM?
Turn off Data Roaming on your home SIM, use Airplane Mode at sea, and set your travel eSIM as the data line in port. Disable Wi‑Fi Assist/auto “switch to mobile data.”
Should I buy the cruise line Wi‑Fi?
Buy the smallest plan that covers your needs at sea (messaging, email). Push all heavy tasks to port with eSIM data. If you need video calls at sea, expect to pay for the top tier and still see variability.
Can I hotspot to family devices?
Yes, in port with your eSIM it’s usually fine and cost‑effective. Onboard, hotspots may be blocked and performance is limited — not recommended.
What if my itinerary spans many countries?
Choose a regional plan like Esim Western Europe or Esim North America. For deep usage in one country, add a larger single‑country plan such as Esim Spain or Esim United States.

The bottom line

Cruise internet isn’t all‑or‑nothing. Use ship Wi‑Fi at sea for the basics, and make port days your high‑speed windows with a well‑chosen eSIM. Plan your eSIMs by region, download offline tools per port, control your phone’s data settings, and batch heavy tasks for when you’re docked. You’ll stay connected, avoid shock bills, and actually enjoy the voyage.

Next step: Map your itinerary and pick the right eSIMs on Destinations.

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

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

Set Up eSIM on Google Pixel 9/10: Quick Guide + Troubleshooting

Travelling with a Google Pixel 9 or Pixel 10 and want fast, reliable data without hunting for a local SIM? Good news: with Android 15, adding and managing eSIMs is quicker than ever. This guide shows exactly what to tap to install an eSIM on your Pixel 9/10, whether you’re scanning a QR code, entering an SM-DP+ address manually, or attempting an eSIM transfer from another device. We’ll also help you check if your phone is carrier-locked, set the right data/roaming preferences for travel, and fix common activation or connectivity issues.If you’re still planning your trip, pick a plan by country or region from Simology’s Destinations – for example, Esim United States for the USA, Esim Western Europe for multiple EU countries, or country-specific options like Esim France, Esim Italy, and Esim Spain. Heading across borders? Esim North America covers the US, Canada, and more with one plan.Before you begin: compatibility, lock status and prepUpdate first: Settings > System > System update. Android 15 (or the latest available) improves eSIM reliability.Check carrier lock:If your Pixel 9/10 was bought from a carrier, it may be locked. The simplest test is to insert a SIM from another carrier and see if calls/data work. Or contact your carrier to confirm it’s unlocked for international use.If locked, eSIM activation from other providers may fail until it’s unlocked.Find your EID (sometimes needed by support): Settings > About phone > EID.Have a stable internet connection (Wi‑Fi recommended) and at least 30% battery.Know your plan’s activation timing. Some travel eSIMs should be installed just before departure or on arrival; others can be installed early and activated later.Pro tip: Save a copy of your QR code and/or SM-DP+ details in an offline note. If Wi‑Fi is patchy at the airport, you’ll still have the info handy.Install an eSIM on Pixel 9/10 (Android 15)There are three common methods. Start here: - Open Settings > Network & internet > SIMs. - Tap Add SIM. - Choose the option that matches your situation below.Method A: Scan a QR code (most common)On Add SIM, choose Scan QR code (or Use a downloaded SIM > Scan QR code).Point the camera at the QR your provider supplied. If it’s on the same phone, open it on another device or print it.When prompted, confirm Download SIM or Add.Name the SIM (e.g., “Simology EU”) for easy identification.If asked, choose a SIM for mobile data, calls and SMS (you can change this later).Toggle on Roaming for that eSIM if you’re travelling internationally.Method B: Enter SM-DP+ details manually (no QR)If your provider gave you an SM-DP+ address and activation code: 1. On Add SIM, tap Need help? or Can’t scan? Enter code manually (wording varies). 2. Enter: - SM-DP+ address (exactly as given) - Activation code (case-sensitive) - Confirmation code (only if requested) 3. Proceed to Download SIM, then set your data/call/SMS preferences.What is SM-DP+? It’s the server that delivers your eSIM profile. Manual entry is handy if you can’t scan or if your provider supplies codes instead of QR.Method C: Transfer your number from another device (carrier numbers)For postpaid carrier numbers (not typical for travel eSIMs), some carriers support eSIM transfer: 1. On Add SIM, select Transfer SIM from another device (if shown). 2. Keep both phones unlocked, nearby and on Wi‑Fi. 3. Follow the on‑screen prompts on both devices to move the eSIM. 4. Note: Moving an eSIM usually deactivates it on the old phone. Not all carriers support this, and it rarely applies to roaming/travel eSIMs.Set your data and dual‑SIM preferences (important for travel)After installing the eSIM: - Choose data SIM: Settings > Network & internet > SIMs > Preferred SIM for mobile data > select your travel eSIM. - Turn on data roaming on the travel eSIM: SIMs > [your travel eSIM] > Roaming. - Calls and SMS: - Keep your home SIM for calls/SMS if you need to receive OTPs from banks. - Set call/SMS preference to “Ask every time” if you want control per call. - Avoid bill shock: - Disable data on your home SIM (SIMs > [home SIM] > Mobile data off). - Turn off roaming on the home SIM. - APN and 5G settings: - Most eSIMs auto‑configure APN and network mode. If data doesn’t work, check SIMs > [your travel eSIM] > Access Point Names. Add the APN provided by your eSIM supplier if none shows. - Try toggling 5G/4G (LTE): SIMs > [your travel eSIM] > Preferred network type. - Hotspot/tethering: - Settings > Network & internet > Hotspot & tethering. Ensure your plan allows hotspot use.Pro tip: Give each SIM a clear label (SIMs > [SIM] > Edit) like “Home” and “Simology EU” to avoid using the wrong line.Troubleshooting: Pixel eSIM won’t activate or connect1) Can’t download/activate the eSIM profileCommon causes: - No or unstable Wi‑Fi/mobile data during download. - Wrong SM-DP+ or activation code; extra spaces or case errors. - Carrier lock still active. - eSIM has already been installed on another device or exceeded download limits. - Date/time not set to automatic, causing certificate errors.Fixes to try: - Use a strong Wi‑Fi network. Turn off VPN during activation. - Double‑check the SM-DP+ address, activation code and confirmation code. Type carefully. - Restart your Pixel. - Set date/time to automatic: Settings > System > Date & time > Use network-provided time. - If your eSIM is EID‑locked by the provider, confirm the EID in Settings > About phone > EID matches what you supplied. - If you suspect a carrier lock, contact your original carrier to unlock the device for use with other carriers. - Remove any partially downloaded eSIM (SIMs > [problem eSIM] > Delete) and try again.2) eSIM installed but no signal or “No service”Ensure the line is turned on: SIMs > [your travel eSIM] > Use SIM = On.Data SIM set correctly: Preferred SIM for mobile data > your travel eSIM.Turn on data roaming for the travel eSIM.Toggle airplane mode on, wait 10 seconds, then off.Try network mode changes: 5G > 4G (LTE) > 3G if available.Disable “Automatically switch data” if the phone keeps flipping to your home SIM.3) Data issues: connected to network but no internetCheck APN: SIMs > [your travel eSIM] > Access Point Names. Add or select the APN given by your provider.Reset network settings: Settings > System > Reset options > Reset Wi‑Fi, mobile & Bluetooth. Then reboot and re‑enable the eSIM.Turn off VPN, Private DNS (Settings > Network & internet > Private DNS > Off), and any firewall apps temporarily.Wait a few minutes after landing; roaming registration can take time.4) Calls/SMS not working as expected (dual‑SIM)Ensure calls/SMS are assigned to the correct SIM: SIMs > Preferred SIMs > Calls/SMS.If RCS/Chat messages misbehave, disable and re‑enable RCS in Messages > Settings > RCS chats.Some travel eSIMs are data‑only. Use apps (WhatsApp, FaceTime audio, etc.) for calls/messages, or keep your home SIM active for SMS/OTP.5) Still stuck?Power cycle: fully power off, wait 20 seconds, power on.Try the install again via the alternate method (QR vs SM-DP+ manual).Contact your eSIM provider with your order number, EID, IMEI (Settings > About phone), and screenshots of any error messages.Pro tips for travellers using Pixel eSIMInstall before you fly: Download the eSIM profile at home on strong Wi‑Fi, but switch data to it only when you land (if your plan timing allows).Keep your home SIM for SMS only: Turn off data and roaming on your home SIM to avoid surprise charges, but receive OTPs if needed.Offline copies: Save QR/SM-DP+ details and support contacts in an offline note or PDF.Use hotspot wisely: Pixel hotspot works well; check your plan’s tethering allowance.Battery and radios: If speeds dip, toggle airplane mode or 5G/4G, or move to clearer coverage (indoors can reduce 5G performance).Choosing the right Simology eSIMNot sure where to start? Browse by region or country on Destinations.USA trip: pick Esim United States.Multi‑country Europe: go with Esim Western Europe.For single‑country plans: Esim France, Esim Italy, Esim Spain.North America hops (US, Canada, Mexico): choose Esim North America.Managing teams on the road? Centralised purchasing and billing are available For Business.Building travel products or bundles? Partner with us via the Partner Hub.FAQCan Pixel 9/10 use more than one eSIM? Yes. You can store multiple eSIM profiles and switch between them. Only one line can be active for mobile data at a time, and voice/SMS options depend on your device/carrier features.Do I need Wi‑Fi to install an eSIM? Strong Wi‑Fi is recommended for the initial download and activation. Some activations work on mobile data, but Wi‑Fi avoids dropouts and captive portals.What’s the difference between QR and SM‑DP+ manual entry? Both install the same eSIM profile. The QR simply encodes the SM-DP+ address and activation code. Manual entry is useful if you can’t scan.How do I know if my Pixel is carrier‑locked? If you bought from a carrier, it may be locked. Test with a SIM from another carrier or contact your carrier to confirm/unlock. A lock can block third‑party eSIM activation.Can I move my travel eSIM to another phone? Usually not. For security, many eSIMs are single‑device. Ask your provider about a reissue if you change devices. Carrier number eSIMs may support official transfer.My eSIM shows “Connected” but no internet. What now? Set the travel eSIM as your data SIM, enable data roaming, verify APN, toggle 5G/4G, disable VPN/Private DNS, and reboot. If still failing, reset network settings and re‑add the eSIM.Next step: pick your plan by country or region on Simology’s Destinations, then follow the steps above to install on your Pixel 9/10. Safe travels.

Travel Privacy Checklist (2025): iOS & Android Settings to Toggle Before You Fly

Travelling with a smartphone means carrying your identity, payment cards, and digital life through unfamiliar networks, borders and busy spaces. Good news: you don’t need new gadgets to stay private.

Get a local eSIM from Destinations (e.g., Esim Western Europe, Esim North America, Esim United States, Esim France, Esim Italy, Esim Spain).If you must use public Wi‑Fi, avoid sensitive logins; use a reputable VPN and Private Relay (iOS) where possible.Don’t plug into unknown USB ports. Use your own charger or a USB data blocker.Keep Bluetooth and NFC off in crowded areas; enable only for the duration you need.Be cautious with QR codes; open in your browser, not unknown apps.Install apps only from official stores; avoid sideloading whilst travelling.After your trip, review and revert any temporary settings you changed.One‑page PDF and screenshot calloutsDownload: “Travel Privacy Checklist (2025) – One‑Pager PDF” from this article’s page and save it to Files/Drive for offline access on the plane.Screenshot callouts to capture after toggling:iOS: Stolen Device Protection On; AirDrop set to Contacts Only; Location Services System Services with Significant Locations Off; Safari “Hide IP Address”.Android: SIM card lock On; Lockdown in power menu; Wi‑Fi scanning Off; Find My Device On.Create an album “Travel Privacy” to keep all proof‑of‑settings in one place.Quick checklist (tick as you go)Update OS and apps; strong passcode/PIN (6+ digits or passphrase).Turn on SIM PIN; store the PIN securely.iOS: Stolen Device Protection On; Android: Lockdown available in power menu.Lock screen: hide previews; limit control centre/quick settings from lock screen.AirDrop/Nearby Share restricted (Contacts Only or Off).Location: “While Using”; Precise Off where possible; Significant Locations Off.Wi‑Fi: Private Address On (iOS); auto‑connect to open networks Off (Android).Bluetooth/NFC Off by default.Safari/Chrome hardened; Private Relay/VPN configured.Find My iPhone / Find My Device On with offline finding; test from web.Backups completed; 2FA backup codes saved offline.Password manager “travel mode” enabled.Public USB charging avoided; use your own charger.eSIM ready for destination; avoid unknown Wi‑Fi where possible.FAQ1) Is Airplane Mode enough to protect my privacy? - No. It disables radios temporarily but doesn’t change app permissions, tracking, or lock‑screen exposure. Use the toggles above regardless of flight mode.2) Should I carry a “travel phone”? - If you’re high‑risk, a minimal “travel build” (fresh device or factory‑reset with only essential apps) reduces exposure. For most travellers, the checklist here plus good habits is a solid balance.3) Does using an eSIM help with privacy? - Yes, eSIMs reduce SIM‑swap risk from physical theft and let you avoid insecure public Wi‑Fi by relying on mobile data. Choose a plan for your region via Destinations or direct picks like Esim United States and Esim Western Europe.4) What about device inspections at borders? - Rules vary by country. Minimise on‑device data, use strong screen locks, and keep backups. Consider a travel‑only profile. This is not legal advice—research your route and requirements before departure.5) Will Stolen Device Protection or Lockdown Mode make my phone unusable? - Day to day, no. Stolen Device Protection adds extra verification for sensitive changes when away from familiar locations. Lockdown is optional and can be toggled when you need maximum protection.6) My phone is lost abroad—what now? - Immediately: use Find My (Apple/Google) to mark as lost, attempt locate, and remotely erase if needed. Change critical passwords. For connectivity, activate a replacement eSIM from Destinations or region pages like Esim North America to stay online while resolving logistics.Next stepPick your secure, local data plan before you fly.
