AT&T 3G Network shutdown information
As of February 22nd, 2022, AT&T, due to ongoing network improvement and 5G service expansion, will phase out its 3G network. This article will describe what steps are necessary to prepare for upcoming changes.
What actions do I need to take?
While AT&T will shut down its 3G network, Teltonika Networks devices will still work with other 3G service providers. There will be a required firmware upgrade to make sure that 4G/LTE Category 1, 3 and 4 devices in the U.S could still connect to 4G even after the scheduled sunset.
You must upgrade the affected devices (table below) to the latest firmware before February 22nd, 2022, to avoid cellular service issues on AT&T 4G network. Failing to execute the following action will leave your devices unable to use mobile data connection.
