Can GoBridge be the sole communication device?

Wondering if a GoBridge was added to my system if the Cell Module would still need to be installed. We had dropped the other provider quite some time ago and would like to know if this was an option, or if a new unlocked module would still need to be purchased?

All accounts require a cellular communication module. An account cannot be created without one.

The Go!Bridge would provide concurrent dual path signaling, so signals would be sent via both methods simultaneously to ensure communication.
