Mobile carriers are sunsetting 3G soon. Will your ELD be affected?

Dec 6, 2021 FMCSA Updates

Mobile carriers are shutting down their 3G networks to make room for more advanced network services, including 5G. As a result, many older cell phones and other mobile devices will be unable to use data services.

Once a 3G network is no longer supported, it is highly unlikely that any ELDs that rely on that network will be able to meet the minimum requirements established by the ELD Technical Specifications, including recording all required data elements and transferring ELD output files.

Therefore, 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.

The announced sunset dates are below.* These are dates for completing the shutdowns. Mobile carriers are planning to retire parts of their networks sooner.

  • 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

Note: Many other carriers, such as Cricket, Boost, Straight Talk, and several Lifeline mobile service providers, utilize the AT&T, Verizon, and T-Mobile networks.

*Sunset dates are subject to change. Contact your mobile carrier for up-to-date information.
