2 people found this review helpfulI was told by other companies that my system could not use a cellular communicator because it was too old. I knew there had to be an application that would allow for this. I finally came across geoarm security and they told me that i could do cellular monitoring with the telguard tg-1 express wireless cellular communicator. I choose the verizon version because the service was better.
