AT&T Rolls Out Wi-Fi Calling To The Galaxy S7/Galaxy S7 Edge

Today, AT&T has started pushing out an update to the Samsung Galaxy S7 and Galaxy S7 Edge which introduces Wi-Fi calling. The update will be listed as build "UCU2APG1" and finally introduce the capability for both of Samsung's current 2016 flagship to make voice calls over Wi-Fi connections as opposed to the cellular network. It also adds a number of other useful improvements that should enhance the overall device experience. More specifically, the changelog mentions IPME, AMBS Phase 3, and Setup and Transfer additions. For the uninitiated, IPME is AT&T's advanced messaging system designed for the wireless carrier's postpaid customers to whom it allows sharing of multimedia files which are up to 10MB in size with other AT&T customers.

Furthermore, the official documentation states the latest Galaxy S7 and Galaxy S7 Edge update also weighs almost 600MB. In other words, it's recommended you download it over Wi-Fi as that could take a hefty chunk out of your high speed data for the month. Despite the fact that the carrier states that the UCU2APG1 is launching today, it's possible that some users still won't be able to download it at this very moment and may have to wait a few more hours before it becomes available for an over-the-air installation. It's also entirely possible that it may take a couple of days for it to surface for all users with these two devices on the network. Just in case users want to check for the update manually, they can do so by navigating to the Settings menu on the device and tapping on System, About device, Software update, and then finally the "Check for updates" option. Devices will also periodically check for the latest update and notify users when it's available for download. If users want to postpone the patching process for whatever reason, it's possible to do so up to three times in four-hour intervals, i.e. for up to 12 hours in total. Note that this update won't bump up the Android OS version which still remains at Android 6.0.1 Marshmallow after installation.

The Galaxy S7 and Galaxy S7 Edge aren't the first phones to receive the Wi-Fi calling functionality from AT&T as the wireless carrier has already brought the same feature to the LG G4 last month. The option can come in handy if you're in an area with a horrible signal reception given how it utilizes special algorithms which translate 2G voice signals to and from data packages quickly enough to be used as a calling service. AT&T has already confirmed that it will keep updating its flagship devices with Wi-Fi calling so more similar software updates are expected to follow in the coming weeks.
