What is 3G?

3G technology allows wireless devices to connect to the internet. Cellular carriers have developed LTE - a stronger, more reliable technology. As a result, 3G technology will be phased out in 2022.

Some older Monitronics security systems have 3G connectivity. Monitronics is upgrading these systems to the latest LTE technology at no cost. Speak to a Monitronics expert to learn more.
