Next 3G Sunset Date Is March 31, 2022

First published by FMCSA

Are you prepared for the 3G sunset?


Mobile carriers are shutting down their 3G networks, which may impact motor carriers if their ELDs rely on a 3G network. Read more about the 3G sunset.
T-Mobile will complete the shutdown of Sprint’s 3G CDMA network by March 31, 2022.
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.

FMCSA has granted an extension for specific 3G dependent ELDs. See which ELDs are covered by this extension.

Motor carriers should be working with their ELD providers to upgrade or replace ELDs that rely on a 3G network.
What actions do motor carriers need to take now?
Confirm whether your ELD relies on a 3G networkIf 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 planIf 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 to complete the necessary actions as soon as possible. Even if your ELD is covered by the extension, you must still replace your device by the extension deadline. Once you receive your upgraded or replaced device, you should no longer use paper logs.
FMCSA strongly encourages motor carriers to take the above actions as soon as possible to avoid compliance issues. See the announced dates listed below and plan accordingly to avoid service disruptions and compliance issues. Note that portions of carrier 3G networks will be unsupported in advance of the announced sunset dates.
