I'm not sure what I'm doing wrong, but I can't connect to the internet with my Straight Talk SIM installed in my Dinc2. The phone works. I 've got it set to GSM/UMTS, and mobile network, but it won't connect unless I have a local wi-fi. I tried to change my APN settings, but it's blank, and I'm not able to change it. HELP please...I'm clueless.
