AT&T to Shut Off 3G in Early 2022


AT&T has set a date for switching off its 3G WCDMA network. Starting February 2022, customers will need a 4G phone with VoLTE technology (a feature AT&T refers to as HD Voice) to connect to AT&T's network. Most smartphones released since 2014 support this technology, as well as most feature phones released in the last two-three years. Phones that will stop working include the Apple iPhone 5s and older, Samsung Galaxy S4 and older, the original Google Pixel, and the OnePlus 6T and older. Shutting down the 3G network will allow AT&T to allocate all of its airwaves to more-efficient 4G and 5G technologies, enablin
