So I just purchased a Nokia Lumia 920 and have so far been very impressed with the phone. The only problem is that I haven't been able to get the data working yet. I am using it on Straight Talk with a tmobile sim in it. I am able to make and receive calls and text messages as I got an unlock code for the phone, but I still can't seem to find some APN settings for data/mms that work. Anyone else having this problem? Anyone have any solutions?
