Resideo Confirms CDMA Sunset Date

Posted By

Resideo has confirmed that the Verizon CDMA Sunset date is December 31, 2022. After that date, Verizon CDMA Communicators for security systems will no longer function. You must replace your panel's cellular communicator before that time to avoid any interruptions to your monitoring service.


In an effort to dispel any false rumors and/or misinformation, Resideo is reconfirming the Verizon CDMA Sunset for alarm panels to be at the end of 2022. The reason why Resideo found it necessary to confirm this shutdown date is because most CDMA Communicators for cell phones had a shutdown date to stop working after December 2020. This date was originally set for the end of December 2019, but it was later pushed back to the end of 2020. However, Resideo has a special agreement with Verizon to keep alarm system CDMA Communicators operational until December 31, 2022. Additionally, the largely equivalent AT&T 3G Communicators for alarm systems are set to stop working after January 31, 2022. This is according to a banner posted on the Resideo AlarmNet website.

The big thing to take away here is that nothing has changed. The 3G and CDMA Sunset impacting the security industry is still on-track to occur next year, in 2022. For AT&T 3G Communicators, this will take effect following January 31, 2022. For Verizon CDMA Communicators, the key date is December 31, 2022. In preparation for these dates, any 3G, 4G, or CDMA radio can no longer be activated for monitoring service. If you deactivate these modules for any reason, you will not be able to reactivate them. But if no changes are made, then they should continue to function until their associated shut-off dates.

As a reminder, Alarm Grid is urging anyone still using a 3G, 4G, or CDMA communicator to upgrade to an LTE communicator as soon as possible. We know that it is tempting to wait until the last minute, especially if money is tight. But please understand that many other users are thinking the same thing. There is most likely going to be a mad rush of users trying to upgrade right at the very end. And while we will do our very best to accommodate everyone, we are unfortunately expecting that some users may get left behind, simply because they didn't act to upgrade their communicators soon enough. Don't risk it. Upgrade now, and ensure that your home or business stays protected well into the very distant future.
