The 3G Network Shutdown Will Impact Phones And More

What is happening? Mobile carriers are shutting down their 3G networks to make room for 5G. Many older cell phones will be unable to make or receive calls or use data services because of this. 3G mobile phones and certain older 4G mobile phones that don't support HD Voice will be affected. 

When is it happening? Plans to phase out 3G services will vary by company. The most up-to-date information can be found on your mobile provider's website. AT&T will shut down its 3G network by February 2022. The 3G network will be shut down by December 31, 2022. T-Mobile will shut down its 3G CDMA network by March 31, 2022, and its 4GLTE network by June 30, 2022. It has not yet said when it will shut down its 2G network. Some devices only need a software update to enable advanced services. If you purchased your phone independent of a mobile provider, you should be able to check whether your device is 4GLTE (with VoLTE or HD Voice) enabled by checking your phone's settings or user manual, or by searching your phone's model number on the internet. 

Other devices, such as certain medical devices, tablets, smart watches, vehicle SOS services, home security systems, and other connected products may be using 3G network services.
