View a timeline of the upcoming 3G sunset dates.

Major wireless network carriers are in the process of phasing out their 3G networks. Commonly referred to as the 3G sunset, this is the period when wireless carriers shut off their 3G services to make room for upgraded connectivity. When this occurs, all devices that are not 4G (LTE) compatible or higher will no longer receive cellular service.

What does the 3G sunset mean for you?

The 3G sunset could mean loss of connection to vehicle and driving data for fleets that have not yet upgraded their telematics devices. Fleets with 3G vehicle tracking devices will need to migrate to 4G devices in order to prevent loss of signal and data transferring.


The 3G network shutdown is not expected to be completed until the end of 2022, but some networks are already beginning their phase-out. One of the first sunset dates for a major cellular network in the U.S. is expected to occur on December 31, 2020.

What can you do to prepare?

To help prepare for the 3G/4G transition, there are several things fleets can do to prepare. As an example, fleet managers can start by checking all installed devices to determine how many are still operating on 3G networks. Creating an installation plan for new 4G-supported devices is an important next step.


One option to make this technology migration and future ones easier, is to upgrade to Geotab’s ProPlus Plan. This plan includes a limited lifetime warranty that covers your fleet for all future network shutdowns and provides replacements for failed devices. The plan also supports advanced driver coaching, advanced IOX support and electric vehicle monitoring.
