Clients whose fire/security alarms use cellular communications as the reporting path to the central monitoring station should note the following caveats:

• Systems that operate over 3G networks will become inoperable once wireless carriers phase out 3G in 2022. These phase outs are already underway. Completion dates vary by carrier but will occur as early as Jan. 1, 2022, in the case of Sprint (by new owner T-Mobile). Unless upgraded, these alarms would not communicate with central monitoring stations during a fire, disaster or security incident.
  
  
• If your system is served by 3G, updating our system is strongly recommended due to these phase outs. Contact Advanced Global Communications at 502-583-6000 or [email protected].

Background

Mobile carriers are shutting down 3G networks, which rely on older technology, to make room for more advanced services, such as 5G. Completion dates will occur throughout 2022, with precise timelines depending on the carrier. More information is available at the Federal Communications Commission’s website.
