AT&T has just confirmed that February 22, 2022 is the day when its 3G network will be discontinued and all phones that don’t support at least 4G LTE and HD Voice will stop working.
that it will sunset its 3G network in February 2022 without giving customers an exact shutdown date. Early this week, the carrier confirmed that February 22 is the day when its 3G network will be discontinued and all phones that don’t support at least 4G LTE and HD Voice will stop working.
If you own an Apple device, things are much simpler, as everything from iPhone 6 and up will work on the AT&T network after the carrier phases out its 3G network.However, if you’re using an Android smartphone, you absolutely mustthat remain compatible with AT&T’s network after February 22.
Finally, it’s worth mentioning that many AT&T customers received a letter about getting their incompatible 3G phones replaced for free.

However, the general consensus is that these are just temporary replacements, not meant to be used as daily drivers for too long.
