AT&T becomes the first carrier to shut down its 3G network this week. Beyond mobile phones, here are some of the devices that could be impacted.
5G is a new technical standard for wireless networks that promises faster speeds and less lag.— AT&T and other telecom companies are also moving to shut down old networks in an effort to free up bandwidth for newer, and potentially more profitable, services. . T-Mobile will shut down its 3G network by summer and Verizon in December.
For AT&T and other carriers, shutting down 3G is an efficiency move. As they upgrade to the latest technology, they shut off outdated networks and use the freed-up bandwidth for newer — and what they hope will be more profitable — services. AT&T says that delaying the shutdown would hurt its 5G rollout, degrading its customers' ability to use their service and causing more dropped calls.
AT&T says it has reached out to offer its customers free replacements via letters, emails and texts. Spokesperson Jim Greer said fewer than 1% of AT&T's consumer devices, including phones, tablets and watches, will lose cellular service, but declined to say how many devices that is.
