GSM Cellular Alarm Communicator
There are ADT Monitored Home Security Systems that use a GSM Cellular Alarm Communicator and do not require you to have a landline phone. In the California residential security industry, many new homeowners are deciding to not have a phone line installed in their home and many existing homeowners are discontinuing their current phone service. By just using their mobile phones, customers can eliminate their home phone service and save some money. Customers are asking us if ADT has Monitored Security Systems and Monitoring Services that do not require the use of a phone. ADT does have a couple of options.
