I did the shop with no issues.
When I got to the correct location, I was the only one in the store. The sales dude was awesome. As he was setting my phone up, I looked at the huge map on the wall. Basically, it said that 94% of America had coverage for talk and text. That was the purple area. The little sporadic orange dots represented 4GLTE coverage. That was enlightening.
Sales dude told me that if I needed to do a return, the activation fee would not be refunded. I made sure to use my debit card in case there was a problem.
I went in the next day to make the return. Dude wasn't working, and when the SA asked if there was a problem, I told her I could not get an internet connection at work. She gave me a full refund on the spot, including the activation fee, which was dude's commission.
