AT&T’s Wi-Fi calling is a great feature to have in areas where the carrier’s signal is not very strong. If you can’t get a call out on AT&T’s network, look for a viable Wi-Fi signal in the area. Once you connect to that signal, you can use Wi-Fi calling to make that call, send a text, or listen to visual voicemail messages.
Today, an update sent out by AT&T to subscribers with the Samsung Galaxy S7 and Samsung Galaxy S7 edge adds Wi-Fi calling to those phones. The new software version is MMB29M and the file is roughly 600MB.
