Unlocked a new verizon Tour. Purchased an "orange" AT&T sim card and had them activate it at the AT&T store along with a new number with the pay as you go plan. While I am able to get text messages, I am not able to make or receive any calls, I get an error message that says "congestion" along with a busy signal... I called AT&T they informed me there were no outages in the area. I get full bars for signal and it says EDGE...
What am I doing wrong???
