As you know, mobile carriers are shutting down their 3G networks. As a result, many older cell phones and other mobile devices will be unable to use data services. This may impact motor carriers if their ELDs rely on a 3G network to record hours of service (HOS) data and transfer it to a safety official.
The first announced 3G sunset date is February 22, 2022, when AT&T will complete the shutdown of its 3G network.
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.
What actions do motor carriers need to take now?
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 t
heir 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 to complete the necessary actions as soon as possible.
The first announced 3G sunset date is February 22, 2022, when AT&T will complete the shutdown of its 3G network.
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.
