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.
