Coverage in Mexico

ALTÁN Redes operates a wholesale LTE network on B28 (700 MHz) used by MVNOs; coverage is extensive but limited to 4G. Telcel 5G n5 uses DSS and is widely deployed, while n78 is limited to select urban areas. B28 is a band commonly absent from US-market phones.

Common Questions

The details worth knowing about your Mexico eSIM

It connects to Telcel, AT&T Mexico, Movistar, and ALTÁN Redes. Telcel provides the widest 4G and 5G coverage, including rural areas. ALTÁN Redes offers extensive 4G-only coverage via its wholesale network. AT&T and Movistar are strong in cities and along highways.

Yes. ALTÁN Redes (used by many MVNOs) relies solely on 4G band 28, which many US-market phones do not support. Without band 28, you will miss that coverage entirely. Telcel, AT&T, and Movistar do not use band 28, so their networks remain accessible on standard US bands.

The eSIM does not cover any specific territories outside continental Mexico. Coverage on islands such as Cozumel or Isla Mujeres depends on whether Telcel or another operator has a local tower; some resort areas have good 4G, but remote islands may have no service at all.

There is no widespread content filtering or throttling applied to this eSIM. However, some operators may deprioritize roaming data during congestion, reducing speeds. The median download speed in Mexico is 35.82 Mbps, but heavy usage can be slower in crowded areas or on ALTÁN Redes.

No. This eSIM is a roaming service, not a local SIM, so it bypasses Mexico’s local SIM registration and ID rules. Activation is done online before travel. No passport or Mexican registration number is required. You connect as a foreign roaming subscriber.
