Google recently released their own version of a Mobile Messenger that is supposed to include all types of messaging, completely replacing Google Talk. While SMS support hasn't been included yet, it does have a video call feature that works really well. However, if you are an AT&T user and you want to use this over cellular data, you will get a message telling you to connect to a WiFi network otherwise you cannot use it.AT&T gave a statement on this, saying that all customers that want to use video calling on apps that are installed after the purchase of the device are free to do it with both cellular and Wifi connectivity. However if an app comes pre-installed on the device, like the case with Google Hangouts (because it replaces Talk), the customer has to be on the Mobile Share option from AT&T.This makes some sense because this way AT&T can prevent some of its bandwidth being eaten up, but meanwhile, iPhone users of Hangout can freely use the Call feature even on Cellular data, so that's not really a fair deal.How to enable Video Calls on AT&T Hangout app:Luckily a solution to this issue has already been found, though it requires the phone to be rooted. If you are willing to do this, or you have already done it then head over to Google Play and download SQLight editor and Root Explorer. Then open Root explorer and head over to /data/data/com.google.android.gsf/databases/gservices.db. Click on it and then click on 'main'. Look down for gtalk_vc_wifi_only and highlight and hold it. You will see the 'Edit record' option, click on it and then change the 'value' to false (it will be set on true). Reboot your device and that's it.
