What it means for IoT devices on AT&T Mexico
- 2G devices no longer connect to AT&T Mexico. Trackers, alarms and meters that only speak GSM/GPRS need a 4G-based replacement, or a SIM that roams onto another network in Mexico still running 2G.
- 3G keeps running for now: AT&T Mexico has announced no closing date.
- For new devices, choose 4G-based technologies: LTE Cat-1 bis, LTE-M or NB-IoT where the network offers them.
- Foreign SIMs in Mexico: no law we found restricts permanent roaming; mobile operators set the terms. Details on the Mexico page.
An M2M.global IoT SIM is not tied to a single network in a country, and its data can reach your cloud without the internet through private delivery.
