Some AT&T users are receiving emails and texts this week, telling them to upgrade their phones or lose service. Some people are asking if the messages are scams (because of the grammar and spelling). And others are getting annoyed because their phones are not that old.

These messages are legitimate. And yet, they are not clear on all the details. Here’s what AT&T cellular customers need to know:

In February 2022, AT&T will kill off their 3G network. After that, older 3G-reliant phones will stop working. Phones that are 4G-compatible (and support HD voice) will continue to work.

So, you don’t really need to do anything until February 2022. Don’t rush out to buy a new phone, if your current one is working just fine.

AT&T has put together a list of phones that will work on their 4G service here: https://www.att.com/ecms/dam/att/consumer/help/pdf/Devices-Working-on-ATT-Network.pdf If you don’t see your make and model of phone on the list, and you think it should be (because it’s a newer phone), contact AT&T to press them on the issue. And if you don’t like what you hear, then you have plenty of time to shop around for a new cellular provider!
