Why is 3G shutting down?

Why are 3G networks being phased out? As mobile carriers seek to upgrade their networks to use the latest technologies, they periodically shut down older services, such as 3G, to free up spectrum and infrastructure to support new services, such as 5G .

What Is 3G Sunsetting? 3G sunsetting means that a mobile network operator (or carriers) shuts off the cellular infrastructure required to operate communication devices based on 3G (UMTS, HSPA, EVDO) technology . These 3G networks are slower and less efficient than newer 4G and 5G networks, which share the same spectrum.

All of the major US 3G networks are scheduled to shut down in 2022 . Whether you’re with AT&T, T-Mobile, or Verizon, this may affect your phone, your home alarm system, or even your car.

In this case, 3G/4G is the network being eliminated and is transitioning to the next generation of network known as “LTE”. Simply put, 3G/4G sunset marks the upcoming end of support of aging 3G & 4G networks by telephone companies .
