Yes, the 2GIG GC2 panel can be upgraded from 3G/4G to an Alarm.com LTE cellular communicator as long as the panel firmware is at least 1.19 +. 


(3G/4G has been discontinued by Alarm.com) See Below:


The firmware can be found in the installer programming menu > From the home screen select security, menu, toolbox, enter the master code "default master code is 1111", scroll to the right once and press the version number. The next menu will give you various information about your 2GIG GC2 wireless security system as well as the panel firmware version.

If the 2GIG GC2 is not 1.19 or higher than a firmware update will be necessary. If you already have your 3g/4g module activated your current provider should be able to remotely push through the latest firmware. If for whatever reason they aren't able to do so remotely see below:


To accomplish the firmware update manually you will need the firmware upgrade cable which is part number 2GIG UPCBL2. This cable will be connected to a computer as well as the control panel. Once the update cable has been connected you will need to download the newest firmware version before you can install a LTE cell radio.
