    Bought iPhone4 off my uncle that was previously activated through at&t, I want to switch the phone carrier to straight talk. I called straight talk and they sent me a new sim for the phone. I’m ready to activate but am causious as my uncle purchased an activation kit from Walmart, set phone up only to realize the internet/data didn’t work. Calling and messaging worked but not imsg. I want the phone strictly for the Internet so I don’t want to buy a 45$ card if I can’t recieve data? What am I doing wrong? Is there something in settings i could check for that i possibly have turned off HELP!

      Hi Jacob,
      Assuming you are using the straight talk att sim your data should work. If you update your phone to the latest version of iOS 7, data should work automatically. Obviously, I can’t speak to what problem your uncle may have had and when you sign up for straight talk, there is always some risk that you might not be able to get it to work. They don’t like to give refunds either, so you’ll spend time arguing them trying to get one.
