Starting next week, the first major mobile carrier will discontinue 3G services, which could result Electronic Logging Device (ELD) violations for truckers who haven’t transitioned to compatible devices.

Starting on February 22, 2022, AT&T 3G will sunset to make way for more advanced 4G and 5G services. This is the first major mobile carrier to sunset 3G services, but sunset dates for other carriers are upcoming throughout 2022.

According to a November 2021 warning from the Federal Motor Carrier Safety Administration (FMCSA), drivers who have not upgraded their 3G compatible ELDs could face hours of service violations once sunsetting begins.

The agency says that “any ELD that requires 3G cellular connectivity 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.”

Planned 3G sunset dates are listed below and are subject to change.

• AT&T 3G: February 22, 2022
• Sprint 3G (T-Mobile): March 31, 2022
• Sprint LTE (T-Mobile): June 30, 2022
• T-Mobile 3G: July 1, 2022
• Verizon 3G: December 31, 2022

Some smaller carriers like Cricket, Boost, Straight Talk, and Lifeline use the AT&T, Verizon, and T-Mobile networks.

The FMCSA offered the following action plan to make sure motor carriers remain compliant.

Confirm whether your ELD relies on a 3G network.

If you are unsure if your ELD relies on a 3G network, contact your ELD provider. If your ELD does not rely on 3G, and meets all minimum requirements, no further action is needed.

Ask your provider for their upgrade or replacement plan.

If your ELD relies on a 3G network, ask your ELD provider about their plan for upgrading or replacing your device to one that will be supported after the 3G sunset, and complete the necessary actions as soon as possible.

The earliest announced sunset completion date is February 22, 2022. See all announced dates listed above and plan accordingly to avoid service disruptions and compliance issues. FMCSA strongly encourages motor carriers to take the above actions as soon as possible to avoid compliance issues, as portions of carrier 3G networks will be unsupported in advance of the announced sunset dates.
