Any ELD or telematics device that requires 3G cellular connectivity will cease to operate in 2022. An ELD that uses 3G to perform its functionality will no longer be in compliance with the technical specifications in the ELD rule after the 3G network it relies on is sunset. When in an area that does not support 3G, a 3G device will register a malfunction. In accordance with 49 CFR 395.34, the carrier has 8 days to get the malfunction resolved, in this case by replacement, unless an extension is granted.

The announced sunset dates are below. Mobile carriers are planning to retire parts of their networks sooner.

• AT&T 3G: February 22, 2022
