AT&T 3G Network Sunset February 2022

Dear Valued Digi Customer

 
AT&T announced that they will be shutting down their 3G network in February 2022.  The sunset of the 3G network may impact some 4G LTE devices.  This situation could cause certain 4G LTE devices using voice centric modems to stop working after the 3G network sunset due to the combined 4G & 3G network used by AT&T.
 
Digi has identified the list of modems affected, and the corresponding Digi products that have incorporated these modems.
 
 
 

What Happens If I Do Not Update?

 
If the affected devices are not updated before AT&T sunsets the 3G network in February 2022, the devices will no longer be able to Register on the AT&T network.  The SIM cards within the hardware will look like they are deactivated if the firmware update is not applied.
