As you might know, AT&T will be sunsetting its 3G network as part of an ongoing improvement plan. They will phase out old equipment in order to make room for the 5G future.

From February 22nd, 2022, AT&T will shut down all existing 3G CDMA network.

Most major service providers are also moving in this direction. Since 2016, Verizon has stated publicly that they plan to decommission 3G. Initially in 2019, then postponed to 2020, with their latest announcement designating December 31, 2022.

 

How to prepare for the 3G shutdown

If your device doesn’t support 4G service, it will no longer work on the AT&T network after the 3G sunset. 

However, our SiteManager models with 4G support will still work. As always, we encourage you to run on the latest available firmware. Should you experience connectivity issues with our 4G capable models, please contact our Support.

What happens after the 3G shutdown for 3G-only SiteManagers?

If you still have a SiteManager with 3G only, it will simply not connect anymore, and you will see the status change. It might reboot automatically if it is set up for auto connect – however, it still will not have connectivity.

If you have an expired 3G SiteManager, we encourage you to return it to your local Secomea Distributor for environmentally safe disposal. Your distributor will also assist in advising you on the best 4G model replacement, if needed.
