BlackBerry Curve 8300
8300 won't receive text to one another..
My buddy and I both have a 8300 Curve BB. We can send and receive text messages just fine, to our wives, friends, everyone... EXCEPT him and I. I can't send to him, he can't send to me. It doesn't give an error message, just goes to no mans land. I guess the fact is: we do not RECEIVE one another text messages that we send to one another (they sure get billed, so it's sent to some server) we just can't receive it.
Any idea??
