Plan Ahead for Phase Out of 3G Cellular Networks and Service
January 6, 2022
If your mobile phone is more than a few years old, you may need to upgrade your device before your mobile
provider shuts down its 3G network, to avoid losing service. For more information on your mobile providers' plans for 3G retirement and how you can prepare, contact your provider directly.
What is happening?
Mobile carriers are shutting down their 3G networks, which rely on older technology, to make room for more
advanced network services, including 5G. As a result, many older cell phones will be unable to make or receive
calls and texts, including calls to 911, or use data services. This will affect 3G mobile phones and certain older
4G mobile phones that do not support Voice over LTE (VoLTE or HD Voice).
