3G Sunset Options From Guardian

The 3G Network Is Being Retired.
Here's How It Affects You.


Dear Customer,

As cellular technology continues to progress, cellular providers such as AT&T and Verizon will be phasing out the 3G cellular network on which your system currently communicates. As the network is decommissioned, the strength of your alarm transmissions will become increasingly unreliable until your system no longer communicates.

We want to ensure that your security system will not lose communication with our Central Station, and in order to avoid a lapse in service a new 4G communicator will need to be installed. We have two pricing options for your consideration, listed below.

Option One: Purchase your new 4G Cellular Communicator Outright 

By selecting this option, you will agree to the installation of a new 4G cellular communicator with no change to your monthly monitoring bill. There will be a one-time installation cost of $395.00 plus tax. When this option is selected, you will be authorizing us to contact you to schedule the installation of your new 4G cellular communicator.

Option Two: (Best Value!) Purchase your new 4G Cellular Communicator with Agreement Renewal.

By selecting this option, you will agree to the installation of a new 4G cellular communicator with no immediate installation fee. Instead, your monthly monitoring cost will increase by $9.95.

We appreciate your business and want to do everything possible to ensure that your system continues to work reliably for you.

Please complete the short form on this page to let us know which option you would like to select, and please contact us with any questions. Our email is: 3G@guardiansecurity.com
