In the past, AT&T has been relatively restrictive in allowing apps like Google Hangouts, Skype, and Facetime (in some cases) to work on supported phones via their cellular network thus requiring a Wi-Fi connection. AT&T released a statement earlier today saying they are working on lifting all restrictions for any application's whom are looking to use video calling over 3G and LTE devices therefore you will soon be able to continue video chatting while on-the-go.
For video chat apps that come pre-loaded on devices, we currently give all OS and device makers the ability for those apps to work over cellular for our customers who are on Mobile Share or Tiered plans. Apple, Samsung and BlackBerry have chosen to enable this for their pre-loaded video chat apps. And by mid-June, we’ll have enabled those apps over cellular for our unlimited plan customers who have LTE devices from those three manufacturers.
Throughout the second half of this year, we plan to enable pre-loaded video chat apps over cellular for all our customers, regardless of data plan or device; that work is expected to be complete by year end.
Today, all of our customers can use any mobile video chat app that they download from the Internet, such as Skype.
This means those of us with grandfathered “unlimited” data plans will finally be able to Facetime over 3G/LTE, which up until now was only possible on the lower tiered capped data plans. The final date of when these changes will be effective are not known at this time, but AT&T promises it will be completed before the new year.
