ppc6700 doesn't get calls & texts are slow

[jerryj30701]

Hi. I bought my daughter a ppc6700 and cricket service. She can make calls and send texts but she doesn't receive calls and text messages can take hours to be received and come clumped together. We have wifi in the house and that works fine also. I was actually able to make one succesful call to her phone so it is possible. Any thoughts?
