Cellular carriers such as AT&T, Verizon and T-Mobile are phasing out older 3G networks to
allow for advanced technology such as 4G/5G and LTE.
With carriers ending the support of the 3G network, alarm systems currently operating on 3G technology will no longer be
able to communicate with our monitoring center over the cellular network.
Your system may be affected by the 3G sunset and it is very important that you
contact us as soon as possible to avoid service disruption.
If you have received a letter, phone call or email about upgrading your system,
please complete the request form below to schedule service.
