Could all of your communications go through Google Hangouts? It’s looking increasingly likely as Android Police has alleged screenshots showing that Hangouts will support both SMS and MMS in version 1.3 of the Hangouts application. The app has already consolidated Google Talk chat services and Messenger, leaving Google Voice as another potential part of the service.
The screenshots posted by Android Police show settings for both SMS and MMS data, including a “delivery report for each SMS you send”. In the Hangouts app. you can also see a “via SMS” indicator so you can tell the difference between an instant message and a text message in Hangouts.
While this is just a rumor for now, the evidence looks compelling. And it makes sense for Google to consolidate communications in its Hangouts application, which works on both Android and iOS. Users should be able to communicate with each other in whatever form they wish and even switch among them, say from IM chat to SMS, at will. If this report does pan out, I’d expect Google Voice to follow suit since it has a text message component as well.
