Mexico City Speed Test: MEX Airport, Polanco, Centro Histórico

Mexico City is sprawling, vertical, and dense. Steel-framed malls, packed indoor markets, and long concourses at MEX can make mobile performance swing wildly even within a few metres. This mexico city mobile speed test focuses on three places most travellers hit in a 48-hour window: MEX International Airport (both terminals), Polanco’s outdoor/indoor mix, and the Centro Histórico including covered markets. We ran multiple passes at different times of day and captured latency, download, and upload to create an open, copyable CSV dataset you can use in your own planning.

Headlines: Telcel’s 5G footprint gave the most consistent top-end performance in Polanco and the Zócalo area. AT&T offered usable—sometimes very good—speeds but fell back to LTE more often indoors. Movistar tended to lag outdoors and struggled most in metal-roofed markets. Inside the markets, all networks dropped sharply; positioning yourself near entrances or skylights frequently doubled speeds.

Before you book a plan, scan our quick location-by-location notes and the step-by-step checklist below. If you’re combining Mexico with the US or Canada, consider a regional option like Esim North America. For onward Europe travel, compare Esim Spain, Esim France, Esim Italy, or Esim Western Europe. See all countries on Destinations.

At-a-glance results

  • Telcel 5G led in open-air Polanco and around the Zócalo: median 180–260 Mbps down, 25–45 Mbps up.
  • AT&T 5G was present in pockets; when on LTE, expect 20–60 Mbps down, 8–20 Mbps up.
  • Movistar generally 4G LTE in these areas: 8–40 Mbps down, 2–12 Mbps up.
  • Indoors with heavy metal roofing (markets), all carriers dropped below 15 Mbps; Telcel held a small edge.
  • MEX Airport: usable but congested; 10–40 Mbps down typical at peak times.

Methodology and scope

  • Period: Multiple runs over two weekdays and a weekend day, morning to late evening.
  • Devices: iPhone 15 Pro and Pixel 8 (to smooth out device/radio differences). Dual-SIM when possible; independent runs per SIM.
  • Apps: Ookla Speedtest primary; cross-checked with Fast.com for throughput sanity checks.
  • Metrics: Download, upload (Mbps), latency (ms), radio tech reported by device (5G NSA or LTE).
  • Locations: MEX T1/T2 public landside areas; Polanco (open avenues, parks, and inside Antara/Palacio de Hierro); Centro Histórico (Zócalo area, Alameda, indoor markets).
  • Notes: Results are snapshots, not guarantees. Building materials, crowd density, handset bands, and roaming partners can alter outcomes. Carriers tested: Telcel, AT&T Mexico, Movistar.

Results by location

MEX Airport (Terminals 1 and 2)

  • Terminal 1 Arrivals Hall: Congested. LTE common for AT&T/Movistar; Telcel 5G present but variable. Expect 10–35 Mbps down during peak arrivals; late evenings improve slightly.
  • Terminal 2 Food Court and check-in: Better line-of-sight gives Telcel 5G an advantage (often 80–150 Mbps). AT&T LTE in the 20–40 Mbps range; Movistar 10–20 Mbps.
  • Gates and corridors: Performance fluctuates as you move between glass façades and deep interior sections. Step closer to windows for a quick lift.

Practical takeaway: Sync maps and offline media on Wi‑Fi before boarding. If your work depends on uploads, avoid relying on the gate area at peak times.

Polanco (avenues, parks, and malls)

  • Outdoors (Ejército Nacional, Parque Lincoln): Telcel 5G excelled, commonly 200–350 Mbps down with sub‑25 ms latency. AT&T’s 5G cells offered 120–200 Mbps where available, otherwise LTE around 40–80 Mbps. Movistar LTE acceptable for navigation and social but rarely above 50 Mbps.
  • Inside Antara/Palacio de Hierro: Speeds dropped but stayed serviceable. Telcel 5G often persisted (120–220 Mbps). AT&T sometimes fell to LTE (20–60 Mbps). Movistar often in low double digits.

Practical takeaway: For heavy tasks (video calls, large downloads), step outdoors or near mall atriums.

Centro Histórico (Zócalo, Alameda, side streets)

  • Outdoors: Telcel 5G solid around the Zócalo and Alameda (150–260 Mbps). AT&T mixed—some 5G pockets; LTE generally 30–70 Mbps. Movistar LTE 15–40 Mbps, occasional dips in narrow streets.
  • Indoors (cafés, stone buildings): Attenuation is significant. Even Telcel 5G can drop to LTE or lose capacity in deep interiors.

Practical takeaway: Position near windows for calls. Pre‑download ride‑hailing and translation packs.

Indoor markets: Mercado de San Juan and La Ciudadela

Metal roofing, dense stalls, and reflective surfaces punish high frequencies. Expect the biggest decline here.

  • Mercado de San Juan: Telcel often fell back to LTE with single‑digit uploads. AT&T/Movistar could dip below 10 Mbps total throughput.
  • La Ciudadela: Slightly better near entrances and central corridors; speeds still modest.

Practical takeaway: If you plan to pay or message vendors, move towards entrances or courtyards. Enable offline payments or carry a small cash cushion.

Notes and caveats: - Snapshot dataset; conditions change with network load, maintenance, and handsets. - If you’re using an eSIM that roams, your underlying partner network (often Telcel or AT&T) determines your real-world performance. - We didn’t test every colonia—use this as a directional guide and add your own samples if you’re extending the dataset.

What this means for travellers

  • Streaming and video calls: Outdoors in Polanco or near the Zócalo on Telcel 5G: smooth 1080p and stable calls. AT&T 5G or strong LTE: fine at 720p. Inside markets: keep calls audio-only if possible.
  • Navigation and ride‑hailing: All three carriers are fine outdoors. In markets, pin and request rides near entrances for quicker updates.
  • Tethering: Telcel 5G comfortably supports laptop work; AT&T LTE is workable for email and docs; Movistar LTE indoors may struggle with large uploads.
  • Payments and messaging: Latency on 5G is snappy (<30 ms). In markets, have offline options or be ready to move for signal.

If you’re crossing into the US before or after Mexico, combine coverage with Esim North America, or use Esim United States for US-only layovers. Continuing to Europe? Compare country packs like Esim Spain, Esim France, Esim Italy, or region-wide Esim Western Europe.

Step-by-step: Get reliable mobile data in CDMX

  1. Pick a plan that maps to your route: - Mexico only vs North America bundle. Check Destinations or go regional with Esim North America.
  2. Check your handset bands: - Ensure your phone supports local LTE and 5G bands; update carrier settings before arrival.
  3. On landing at MEX: - Toggle Airplane Mode off/on once. Allow automatic network selection to settle for a minute.
  4. Test and observe: - Run a quick speed test in an open area. If poor, move 10–20 metres toward windows or open concourses and retest.
  5. Manually switch networks if allowed: - Some eSIMs let you pick a preferred local partner (e.g., Telcel vs AT&T). Trial both if your plan permits.
  6. Optimise indoors: - In markets and deep interiors, stand near entrances, atriums, or skylights. Elevate the phone (chest height) during uploads.
  7. Keep a backup: - Download offline maps, translation packs, and key tickets. Use café Wi‑Fi for big syncs.

Pro tips

  • Short, sharp fixes: Airplane Mode cycle, disable/enable 5G when cells are overloaded, or lock to LTE for stability if calls jitter.
  • Wi‑Fi offloading: Polanco cafés and malls often have reliable Wi‑Fi—use it for large uploads, then switch back to mobile for movement.
  • Dual‑eSIM strategy: If you’re working on the move, carry two eSIMs on different partners and switch by area.
  • Latency matters: For calls, a stable 30–60 ms LTE link can beat a congested 5G cell with 120 ms spikes.
  • Business travel: If your team moves between the US and Mexico, standardise on a cross‑border plan and device profile via For Business. Partners and agencies can coordinate benefits via our Partner Hub.

FAQ

1) Which carrier was fastest overall in this test? - Telcel 5G delivered the highest peak and most consistent outdoor speeds in Polanco and around the Zócalo. AT&T had good 5G pockets but fell back to LTE more often. Movistar was mainly LTE and slower overall.

2) Will I have 5G everywhere in Mexico City? - No. You’ll see 5G in many central, open-air spots, but deep indoors and some corridors (including parts of MEX) will drop to LTE. Plan for variability.

3) Are indoor markets (San Juan, La Ciudadela) workable for video calls? - Usually not. Expect single‑digit uploads and modest downloads. Move near entrances or step outside for important calls.

4) I’m transiting the US and then Mexico. What’s the simplest eSIM approach? - Use a regional plan such as Esim North America. If you only need data during a US layover, consider Esim United States plus a Mexico plan.

5) I’m heading to Europe after Mexico. Should I stack country eSIMs? - If you’re visiting one or two countries, a country plan like Esim Spain, Esim France, or Esim Italy works well. For multi‑stop trips, a regional option like Esim Western Europe is simpler.

6) Can I rely on airport mobile data for work uploads? - It’s hit‑and‑miss at peak times. Download and sync on Wi‑Fi where possible; keep mobile for light tasks and messaging.

Bottom line

Mexico City’s network quality strongly depends on line‑of‑sight and building materials. Telcel 5G shines outdoors; AT&T and Movistar are fine for everyday use but can struggle indoors. In markets, all carriers are constrained—move towards open areas to recover performance. Use our open CSV to plan your day, keep a backup workflow for uploads, and pick a regional plan if you’re crossing borders.

Next step: Compare coverage and pick a cross‑border option on Esim North America.

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 &amp; 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.

SIM Registration by Country (Top 30 Destinations): Do You Need ID? (2025)

SIM Registration by Country (Top 30 Destinations): Do You Need ID? (2025)

Travellers are often surprised to learn that many countries now require “real‑name” registration to activate a local SIM or eSIM. In plain terms: you may need to show ID (usually a passport) and complete a quick form or selfie check before your number works. Other destinations still allow anonymous purchase, especially for data‑only plans. This guide summarises SIM registration by country across 30 of the most-visited destinations, so you know what to expect at the airport kiosk, high‑street shop, or when activating an eSIM in‑app.We update this list quarterly and link out to the most relevant country and regional guides, including Esim United States, Esim France, Esim Italy, Esim Spain, Esim Western Europe and Esim North America. For everything else, browse all country pages via Destinations.What is SIM registration?SIM registration (aka “real‑name registration”) ties a mobile number to an individual using a recognised ID. It usually happens: - At point of sale (airport desk, carrier shop, authorised reseller) - Online or in an app (video KYC, document upload, eID), especially for eSIMAuthorities use it to limit fraud and spam. For travellers, it means carrying your passport and sometimes completing a quick selfie or address check.Quick prep checklist (save this before you fly)Bring your physical passport and one backup photo/scan stored offline.Know your accommodation address (hotel is fine) and a reachable email.Have a payment method that matches your name (card or digital wallet).If you want a local plan on arrival, favour official carrier stores or airport counters for smoother tourist KYC.Consider activating an eSIM before departure to skip queues. Regional options like Esim Western Europe and Esim North America cover multi‑country trips.SIM registration by country: Top 30 (2025)Notes: - “Need ID?” reflects national rules for prepaid activation; retailers can still choose to verify even in “No” markets. - Requirements can change; use this as a traveller’s quick reference and confirm details in‑country.CountryNeed ID?Where to registerAccepted documentsPractical notesUnited StatesNo (not mandated)n/an/aSome carriers may verify identity for fraud prevention.

Some markets (e.g., Japan) require ID only for voice—data‑only eSIMs are simpler.Prepare documents - Keep your passport ready; jot down your hotel address and a local contact (hotel desk works).Choose the right channel - Airport carrier counters and flagship stores handle tourist KYC fastest. - For eSIM, complete the in‑app KYC with good lighting for any selfie/ID scan.Complete registration - Follow staff guidance or app prompts. Don’t leave until you’ve made a test call or used data.Keep proof - Save the receipt, SIM sleeve, QR code/eSIM email, and any confirmation SMS for the duration of your trip.Pro tips from frequent travellersArriving late? Pre‑activate an eSIM before you fly so you have data for ride‑hailing and maps on landing.Airport vs city: Airport kiosks are efficient but sometimes pricier than city shops; decide what you value more—speed or price.Brazil and Turkey specifics: Use official carrier stores; they’re set up for foreigner KYC and can explain CPF/IMEI rules.UK/US/Mexico: Even where registration isn’t mandated, keep your passport and a payment card handy in case a retailer requests verification.Keep it simple for teams: If you’re coordinating for a group or staff, consider centrally managed plans.

That said, many sellers still prefer to see ID. When ID is required, a passport is the safest bet for travellers.Can I register online for an eSIM instead of visiting a shop?Often yes. Many European operators support video ID or document upload for eSIM activation (e.g., Germany, France, Italy, Spain). In some markets (e.g., China), you’ll still need to visit a carrier store.How long does registration take?In store: 5–15 minutes at airport counters, sometimes longer in city shops. Online/app KYC: usually 2–10 minutes if your photos are clear and documents match.What if I don’t have a local address yet?A hotel address is typically acceptable. If asked for a contact number, use the hotel’s front desk.Will my phone get blocked if I use a local SIM?Only in certain markets with IMEI controls (notably Turkey). Tourists can use their phones for a limited period (commonly around 120 days) without registering the device. This does not affect roaming on your home SIM.Is roaming on my home SIM affected by these rules?No. Real‑name rules apply to activating local SIMs/eSIMs. Roaming with your existing SIM works as normal, subject to your home carrier’s rates.Next step: Plan your connectivity per stop with our country pages and regional eSIMs. Start with Destinations.

Navigation & Offline Maps: Google/Apple Maps with eSIM Fallback

Navigation & Offline Maps: Google/Apple Maps with eSIM Fallback

Planning to drive, walk, or cycle abroad and want reliable navigation without burning through mobile data? Here’s the traveller-proof setup: pre-download offline maps in Google Maps or Apple Maps, then use a light-touch eSIM as your live-traffic fallback. This gives you turn‑by‑turn guidance even with no signal, while still benefiting from up‑to‑date traffic, rerouting, and place details when you need them. It also plays nicely with CarPlay and Android Auto.This playbook explains exactly what to pre‑download, how to configure Google Maps and Apple Maps for offline use, how to set up your eSIM as a smart fallback, and how to budget data on the road. We’ll flag the trade‑offs (traffic vs. zero data), cover CarPlay/Android Auto behaviour, and share tested pro tips to avoid glitches. If you’re crossing borders, we’ll also show you how to download regional maps and pick a regional eSIM so you don’t juggle multiple SIMs at the wheel.Why combine offline maps with an eSIM fallbackOffline maps give you guaranteed turn‑by‑turn in areas with patchy signal or in tunnels, mountains, or rural routes.A small amount of mobile data from an eSIM lets your app fetch live traffic, closures, speed limits, POI details, and quicker reroutes.You control the trade‑off: run fully offline most of the time, and let eSIM data kick in for up‑to‑date insights when it matters (city driving, rush hour, roadworks).Works with CarPlay/Android Auto: the maps and guidance are on the phone; the car is just the display and controls.If you’ll drive across several countries, consider a regional plan like [Esim Western Europe] or [Esim North America] so you aren’t swapping profiles at borders. For single-country trips, pick the right local plan such as [Esim United States], [Esim France], [Esim Italy], or [Esim Spain]. Explore coverage by country via [Destinations].What you need before you flyiPhone on iOS 17 or later (for Apple Maps offline) or Android/iPhone with the latest Google Maps.1–3 GB free storage per large region (city sizes are much smaller).A travel eSIM active or ready to activate on arrival. See [Destinations], or go straight to [Esim Western Europe], [Esim North America], [Esim United States], [Esim France], [Esim Italy], or [Esim Spain].A charging cable for CarPlay/Android Auto (wired is more reliable and charges your phone).Optional: car mount for safer glanceable navigation.Data budgeting (typical): - Pure offline navigation: near‑zero data. - Navigation with live traffic: roughly 2–10 MB per hour, depending on area and zoom level. - Searching many places, downloading new regions, or sharing live ETA: can add tens of MB. Your mileage varies by map style, density, and how often you search. The setup below keeps usage predictable.Step‑by‑step: Set up Google Maps for google maps offline travel1) Update Google Maps - Open your app store and update Google Maps to the latest version.2) Download your regions - Open Google Maps. - Tap your profile picture &gt; Offline maps &gt; Select your own map. - Pan/zoom to cover your entire driving area (include airports, detours, border crossings). - Download. Repeat for additional areas if needed. - Optional: rename areas (e.g., “Tuscany”, “Pyrenees crossing”) for clarity.3) Set auto‑update and storage - In Offline maps, turn on auto‑update (Wi‑Fi only). - If storage is tight, switch download location to SD card (Android) or delete old areas.4) Pre‑plan your routes on Wi‑Fi - Search and save key stops (hotels, charging points, fuel, landmarks). - Add to a list or star favourites, so they’re available offline.5) Test offline - Temporarily enable Airplane Mode (leave GPS/location on). - Start navigation to a saved place within your downloaded area. - Confirm turn‑by‑turn works and map tiles are visible.6) Optimise mobile data use - Disable Street View and satellite layers (use the default map). - Use live traffic selectively: turn on when you enter busy zones, off elsewhere. - Avoid downloading new regions on mobile data; use Wi‑Fi.Pro tips for Google Maps: - Combine multiple smaller downloads rather than one huge area to speed updates and keep storage manageable. - For multi‑day drives, download along the whole corridor plus a 50–100 km buffer for detours. - Save offline “Lists” (e.g., “Day 3 stops”) and download their areas; searching by saved places works offline. - Transit directions generally need data. Downloading regions won’t give you live timetables. - If search fails offline, navigate by exact address or coordinates saved beforehand.Step‑by‑step: Set up Apple Maps offline + CarPlay1) Update iOS - Go to Settings &gt; General &gt; Software Update and ensure iOS 17 or later.2) Download maps - In Apple Maps, tap your profile picture &gt; Offline Maps &gt; Download New Map. - Search a city, region, or country; adjust the bounding box; download. - Repeat for all regions you’ll visit, including border areas.3) Auto‑update and options - In Offline Maps, enable automatic updates (Wi‑Fi recommended). - Turn on Optimize Storage if space is limited; Apple will prune less‑used areas.4) Save places and routes - Add hotels and key stops to Favourites; Apple Maps can navigate to these offline. - Pre‑start a sample route on Wi‑Fi to confirm guidance works.5) Use with CarPlay - Connect your iPhone (wired preferred for charging). - CarPlay uses your iPhone’s offline maps automatically. Voice guidance works without data. - Voice dictation and some POI details may require data; plan key searches ahead.Limitations to note: - Live traffic, incidents, and dynamic rerouting require data. - Public transport directions need data for schedules and service changes. - Rich POI details (photos, reviews) may be limited offline.Configure your eSIM as a smart fallbackThe goal: run offline most of the time, but allow small bursts of data for traffic updates, reroutes, and quick searches.On iPhone (Dual SIM/eSIM): 1) Install and activate your travel eSIM (don’t delete your home line). 2) Settings &gt; Mobile Service: - Set the travel eSIM as the Mobile Data line. - Turn off Data Roaming on your home line to avoid accidental charges. - Enable Low Data Mode on the travel eSIM to reduce background use. 3) In Google Maps or Apple Maps, keep default settings; the apps will use small amounts of data when needed.On Android (may vary by device): 1) Install and activate the eSIM. 2) Settings &gt; Network &amp; Internet &gt; SIMs: - Set the eSIM as the preferred SIM for mobile data. - Disable data on your home SIM while abroad. 3) Consider Data Saver mode to restrict background data.Choosing the right plan: - Single-country: [Esim United States], [Esim France], [Esim Italy], or [Esim Spain]. - Multi‑country: [Esim Western Europe] for EU/EEA/UK‑style trips, [Esim North America] for USA/Canada/Mexico. See all options via [Destinations].Data budgeting: how much does navigation actually use?Typical data ranges (indicative; terrain and behaviour vary): - Pure offline with pre‑downloaded maps: near‑zero during active navigation. - With live traffic and occasional reroutes: about 2–10 MB per hour of active driving. - Frequent place searches, exploring photos/reviews, or downloading new areas: add 20–100+ MB over a day. - Live ETA sharing: roughly 0.5–2 MB per 10 minutes of sharing.Ways to keep usage tight: - Download all regions and saved places on Wi‑Fi before departure. - Start navigation on Wi‑Fi when possible; the app caches portions of your route. - Toggle the traffic layer on only in urban areas or at expected bottlenecks. - Use text‑only search; avoid tapping into image‑heavy POI pages on mobile data. - Turn off map layers (3D buildings, satellite) and avoid Street View.Driving with CarPlay/Android Auto on a low‑data eSIMOffline first: both platforms display your pre‑downloaded maps and give voice guidance without data.Traffic smartly on‑demand: keep traffic on when entering congested zones; turn it off for rural stretches.Voice control: on‑device text‑to‑speech works offline. Voice dictation/search may need data; pre‑save destinations as Favourites or Lists to avoid dictation.Media vs. maps: streaming music/podcasts will dwarf navigation data. Download playlists or use car radio to keep total usage low.Phone power: wired CarPlay/Android Auto charges your phone and keeps GPS performance stable.Cross‑border trips: pre‑download by regionWestern Europe road trip: download each major country corridor (e.g., Paris–Lyon–Milan, Barcelona–Valencia–Costa Blanca), plus buffers around borders and ferry ports. Use [Esim Western Europe] to stay on one plan across countries.North America loop: download state/province blocks (e.g., California + Nevada + Arizona, or Ontario + Québec) with buffers on interstates. Use [Esim North America] or country‑specific [Esim United States].City breaks: download the city and surrounding commuter belt. For France, Italy, or Spain, pick [Esim France], [Esim Italy], or [Esim Spain] respectively.Business travel across regions? Centralise procurement and policies via [For Business], and manage partner deployments through the [Partner Hub].Troubleshooting quick fixesCan’t start navigation offline:Ensure you’re inside a downloaded area and the route doesn’t leave it.Use a saved Favourite or exact address. General POI searches may need data.“Map expired” warnings:Connect to Wi‑Fi and update offline maps. Enable auto‑update to avoid future lapses.GPS drift or no location:Disable battery saver while navigating; it can throttle GPS.Mount the phone with a clear view of the sky; avoid placing it deep in the console.Storage full:Remove unused map areas or lower the area size.On Android, store offline maps on an SD card if available.CarPlay/Android Auto disconnects:Use a high‑quality cable or switch to wired from wireless.Keep the phone unlocked the first time you connect after updates.FAQ1) Do GPS and turn‑by‑turn work without mobile data? Yes. GPS is independent of mobile data. With downloaded maps, both Google Maps and Apple Maps provide turn‑by‑turn offline.2) Will I still get live traffic and road closures offline? No. Live traffic, incidents, and dynamic rerouting need data. Use your eSIM sparingly to fetch these when entering busy areas.3) How much space do offline maps take? A large city might be a few hundred MB; a broad region can be 1–3 GB. It depends on density and how much you include. Download only what you need, plus a sensible buffer.4) Can I use public transport directions offline? Generally, no. Schedules, routes, and service changes require data. You can still view station locations offline but not live timetables.5) Does offline search work for places and restaurants? Partially. Both apps support basic offline search within downloaded areas, but detailed POI info (reviews, photos, opening hours) and broad discovery typically need data.6) Can I share my ETA without using much data? Yes. ETA sharing uses modest data (roughly 0.5–2 MB per 10 minutes). Toggle it only when needed to keep usage low.Next step: Choose your region and plan your downloads with [Destinations].
