Pros: Lowest price per GB, fast activation, Mexico coverage on AT&T. Cons: Newer brand, smaller community than Airalo.
Mexico's visitor eSIM market runs on AT&T Mexico (5G), which operates independently of AT&T US. AT&T Mexico covers Cancun International (CUN), Mexico City's AICM and Felipe Angeles airports, Los Cabos, and major Pacific coast resort zones on 5G. Coverage in CDMX reaches into the metro system.
Remote areas of Chiapas, Oaxaca's Sierra Norte, and Baja's desert stretches drop to 3G or no signal.
Coverage analysis
AT&T Mexico delivers 5G across Cancun's Hotel Zone, Playa del Carmen's Quinta Avenida, and Mexico City's Roma, Condesa, and Polanco neighborhoods. The Riviera Maya highway corridor (Hwy 307) maintains 4G between CUN and Tulum. Puerto Vallarta's marina and Zona Romantica areas are well-covered.
Honest limitation: the Copper Canyon railway route loses signal through multiple stretches, and Oaxaca's Pacific coast highway drops to 2G outside Huatulco and Puerto Escondido.
Activation
Install your e-sim QR code before departure. Activate after landing at CUN (Cancun) or MEX (Mexico City). Los Cabos (SJD) and Puerto Vallarta (PVR) airports also connect immediately on arrival.
AT&T Mexico registers your eSIM automatically within 3 minutes of enabling the profile. iPhone XS or newer and Android devices from 2019 onward support Mexico's 5G Band 66.
Data usage tips
Mexico travel needs vary by destination. Uber runs on 30 to 50 MB per ride in CDMX and Cancun. WhatsApp voice and video calls, the standard for local communication, use 80 to 100 MB per hour.
Waze navigation for highway driving consumes 50 MB per hour. Budget 500 MB per day for active tourist use. Hotspot for a laptop adds 1 to 2 GB per day.
A 5 GB plan covers 10 days of standard travel use.
