📶 The "Telcel" Rule
Choose an eSIM that uses the Telcel network. Period.
✓ Telcel (América Móvil)
- • ~70% market share in Mexico
- • Best coverage in beach areas (Tulum, Cancun)
- • Reliable in jungle cenotes and ruins
- • Strongest signal in Mexico City
- • Works on highways between cities
⚠️ Movistar / AT&T Mexico
- • Smaller coverage footprint
- • Dead zones in remote beach areas
- • Weak signal at archaeological sites
- • May drop connection outside major cities
- • Budget eSIMs often use these networks
🔑 Before buying: Check which Mexican network your eSIM uses. Telcel = reliable. Movistar/AT&T = potential issues outside cities.
🚨 Safety Tip: Data is Essential in Mexico
Working data is a safety requirement, not a luxury, especially in Mexico City.
- Uber/Didi: The safest way to travel. Regular taxis can be risky for tourists. You need working data to request rides.
- Google Maps: Essential for navigating CDMX's complex streets and metro system safely.
- WhatsApp: Primary communication in Mexico. Hotels, tours, and restaurants often use it.
- Translation: Google Translate needs data for camera translation of menus and signs.
⚡ Don't try to save a few dollars on data. Having reliable connectivity is a core safety measure for your Mexico trip.
