Hangouts updated, finally lets AT&T users make video calls on mobile network
Hangouts got a new update this weekend, and if you’re an AT&T user, you can now make video calls through cellular data. Making video calls in Hangouts on AT&T was previously only possible via Wi-Fi, but this new update solves all that.
Keep in mind that this isn’t the first time AT&T has blocked video calls on its network. iPhone users may remember the issues they had with FaceTime when that first launched as well.
Other than that, this new version of Hangouts has fixed a bug where messages got stuck in the sending and retrying loop.
