I have att and it works no problem. I purchased a tmobile sim card and activated it and popped it in my phone. Some reason it keeps trying to connect to At&t instead of tmobile network and then it goes for a second and goes into SOS as the signal. I tried manually picking Tmobile network, but that doesnt even show up in the list only At&t does. I know theres coverage in my area and its currently set on GSM/CDMA at 2G. Any suggestions would be appreciated. Thanks.
