Simon XT/XTi VoLTE Module - Verizon, LTE Upgrade XT-511-US-VZ-LTEUP
 
The Alarm.com XT-511-US-AT-LTEUP is designed to be installed in place of a previously registered AT&T 3G or Verizon CDMA communicator in an Interlogix Simon Panel. This module will upgrade the existing panel so that it can take advantage of the AT&T LTE network, and the Alarm.com remote control ecosystem.
