Hey guys, yesterday we saw numerous reports of people unable to connect to AT&T’s data network with their Lumia 900s. We’ve discovered the root of the problem and have put together a short video to show you how to fix it, since the fixes AT&T are giving customers are not really the correct way to solve the problem. Check it out and let us know if the solution worked for you or if your Lumia 900 is still unable to connect.
