For those of you with DMP or Bosch panels running 3G on Verizon or AT&T,

In 2022, both cellular carriers' 3G networks will no longer be in service. Specifically, AT&T’s 3G/HSPA network has shut down as of February 2022. Later this year, in December, Verizon has confirmed it will do the same with its 3G/CDMA network.
To stay ahead of the 2022 sunset, it’s time to start scheduling the replacement of CDMA or HSPA devices as you are doing service work if you haven’t already. To continue to utilize your alarm system after the AT&T or Verizon 3G network becomes unavailable, you must have the cellular alarm communicator that transmits alarms from your security panel to the central station updated.
We are committed to working with you to make this transition as seamless as possible. If you have any questions, please do not hesitate to contact us below.
Important Dates:
AT&T 3G Discontinuation Date: February 22, 2022
Verizon 3G Discontinuation Date: December 31, 2022
