2GIG 4G LTE Cell Radio on AT&T for Alarm.com Overview

2GIG LTE or 3G cell radio module — adds cellular alarm reporting and Alarm.com (or dealer ADC / SecureNet / Telus) interactive services to a compatible GC2, GC3, or Edge panel.

Without reliable cellular reporting, remote arm/disarm and central station signals stop when phone lines or broadband fail. Match the exact module SKU to your panel model and dealer platform before truck roll.
