Your problem could be 2 fold as I had the same issue.
1. The idiot at the cricket store selected the incorrect setting for your phone. I would suggest going to a non-cricket corporate store. A non-corporate store will know the ins and outs of none cricket phone and should be able to set your cricket phone to the correct settings on their computer.
2. Your phone my need to be re flashed but doing the above should get you corrected.

i had the same issue and it wasn't until i took my phone to a hole in the wall store to get it corrected
