Hello- I just got an unlocked 6, and have pay as you go from AT&T. When I turn my wi-fi off, it's saying no cellular data. I had a 4s and downloaded APN settings from http://www.unlockit.co.nz/ but he's saying he doesn't have a 6, and I'm not really sure how to solve this. I know that I've paid for cellular data on my plan. I went to the AT&T store today and got the new sim card and she transferred the info from my old to new phone. Any suggestions or help??? Thanks!
