The 3G sunset may also shut down your alarm systems.
Cellular carriers announced their intentions to shut down all 3G technologies in 2022 in favor of faster and more advanced tech like 4G and 5G networks. This action means that if your farm alarm system includes a 3G cellular transmitter for communication, it will no longer function when the 3G shutdown occurs. Even if it appears to function, it will no longer be able to communicate with a digital cellphone line.
