The carrier’s first Wi-Fi calling update for a Samsung device came three months ago when it brought the feature to the Galaxy S6 Active. It was then expanded to the Galaxy S7 and the Galaxy S7 edge. Today, three additional Samsung handsets are gaining support for Wi-Fi calling on AT&T.
Those who are on this network should look out for software versions G920AUCU4DPH5 for the Galaxy S6, G928AUCU3CPHA for the Galaxy S6 edge+ and N920AUCU3CPHA for the Galaxy Note 5. AT&T hasn’t released this update for the Galaxy S6 edge yet which is a bit odd but it may get the update in the near future as well.
