AT&T 3G sunset to impact over 350,000 Class 8 vehicles

February 22, 2022

Mega telecommunications company AT&T began the sunset of its 3G network Feb. 22 at which point modules and devices that request 3G voice and data-only services from the AT&T network will no longer work – a wind down that will affect more than 350,000 Class 8 vehicles.

AT&T and Verizon began the rollout of 5G wireless services Jan. 19. The deployment of the 5G network offers faster speeds and broader range,  but according to global technology intelligence firm ABI Research, the sunset of 3G will further affect the already strained supply chain.
