All major network carriers in the US, including AT&T and Verizon, have announced they will soon discontinue 3G services and transition to 4G LTE networks. Carriers are not allowing any 3G activations or re-activations and are strongly encouraging users to upgrade their devices before 3G service is discontinued. For AT&T, the sunset of 3G service is expected to happen as early as February 22, 2022, with Verizon no later than December 31, 2022.

While previous PERS devices communicate using CDMA and 3G (GSM) technologies, 4G LTE is the higher performance next generation technology offering faster, more efficient, and stronger broadband services consumers have come to demand. This 4G network provides infrastructure that allows PERS devices to interact with emergency services via the  monitoring service provider (MSP). The network plays an essential role in the ability to send push fall detection and other alert notifications, firmware updates, and device information needed by the MSP for emergency services.

Because most major carriers stopped certifying new 3G parts years ago, manufacturers of cellular devices, like Numera, have stopped making them.
