AT&T today launched WiFi Calling on Android.
Starting with the LG G4, AT&T customers will be able to make/receive calls and send/receive text messages via WiFi. AT&T said customers with compatible phones will receive a notification once the feature is available to them. A small software update is required.
AT&T said WiFi Calling is available to customers with postpaid accounts set-up for HD Voice service. The phone will automatically make calls via WiFi when it detects limited or no cell coverage.
WiFi calls are billed based on the number being called, so AT&T customers can call U.S. numbers via WiFi free of charge when abroad. AT&T said it expects WiFi Calling to be available on more Android devices soon. WiFi Calling has been available to the iPhone since last year.
