Can't text to person in Mississippi...anyone know y?

[TeKNeiN]

I just got my phone and service on the 16th. The only reason I got the phone is so I could text my girlfriend in Mississippi. I subscribed to the $50 Cricket Unlimited Access Plus package. I can text anyone I can think of...except her. When I send a text to her, I get this message back: Your Message could not be delivered. (her phone number) is not a valid wireless device. Her friend in colorado has a cricket phone and can text her. But I can't from Washington. Someone please help me...

hmm. I would imagine it would have to do more with the carrier than it would her location. I honestly never text out of state so I am not sure. Seems like at one time there was some issue with texting to Sprint phones.

Her carrier is cellular south and both companies are telling me that there should be no problem between the two...and she has a friend in colorado that has cricket and texts her all the time

Anyone know the code to get into the program menu on a cellular south phone?
