If you didn't know, the tech world has known that AT&T has had shared data plans in the works for a good amount of time now, and now it is finally becoming a reality. One thing that they are not telling though, is when the party is going to start. The screenshot shown above is an indication that its coming, though. It shows that support for group data has already been added to Telegence, the program that customer service/employees use to manage customer accounts.
Unfortunately, since the new adjustments aren't functional just yet, it could simply mean the company's beginning the first wave of crucial internal testing. Anyway you look at it, it is a good step in the right direction. Now all we need to know is when AT&T's biggest rival, Verizon, is going to come out with a plan similar to this.
Also, here is another screenshot related to this post. I don't know why Engadget's watermarks are even on these photos, because they in no way shape or form own the memo. These screenshots can be found on any other site covering this news without watermarks. I just chose them because they host their photos forever as far as I know.
