Deadlines to Update Some Security Systems Fast Approaching

Mountain Alarm strives to remain at the forefront of technology in order to provide the best and most reliable systems possible.

Due to the telecommunications industry plan to discontinue 3G service and seven-digit dialing, some security systems will require a communication upgrade to ensure uninterrupted service. AT&T 3G will end February 2022 and Verizon 3G will end by December 2022. Service for seven-digit POTS (plain old telephone service) will end by October 27, 2021. We’ve already seen sporadic drops in service depending on location, so it’s imperative that we upgrade the communication technology in those systems affected by the changes.

In the coming weeks and months, we will be notifying customers whose systems use 3G or POTS technology. Our Customer Experience team will need to schedule an appointment to upgrade equipment at many homes and businesses to keep their signals reliable and security systems dependable.

While upgrading these systems is mandated by changes in the telecommunications industry, updating them will not adversely affect any current devices. It can also provide the ability to add smart automation devices including thermostats, lights, locks, garage door controllers, and small appliance modules, which can all be accessed and controlled remotely.

For those systems not currently using cellular technology, upgrading the communication path provides the option to interact with the system remotely. Interactive service allows users to arm and disarm their system remotely and receive real-time notifications and reminders, all from an app on their smartphone, tablet, or computer.

We are currently offering special pricing for all of our upgrade options to facilitate this necessary change. Please call our Customer Experience Department at 1-888-349-3455 or email us at if you have any questions.
