A week after Microsoft released its first major Windows 10 Mobile update to devices that were sold unlocked, the Anniversary Update is now finally rolling out to carrier-locked smartphones. It is confirmed that the update is now rolling out from AT&T.

It is only a matter of time before other carriers start rolling out the Anniversary Update, so you should check your phone for the update notification, but it could take some time for the update to hit your device. You can also head to your handset’s Settings menu to manually check for the update.
