AT&T 3G Sunset 🌅

Dear All,

AT&T will be shutting down its 3G network on February 22, 2022 to make more room for 4G & 5G infrastructure. This change will affect all 3G-only devices and also impact some LTE-capable devices.

What do you need to do?

  • If you use Sixfab CORE Software, it makes all necessary configurations for your modems. You just need to be sure the CORE version is up-to-date.
  • If you use Sixfab SIMs without CORE Software or AT&T SIMs, you need to make some configurations manually on your modems. Please follow our AT&T 3G Sunset Guide.

If you have any issues or concerns please contact us.

Yours Sincerely,
Sixfab Team
