idunno is right a little more info is needed, though we know you are rooted, but are you rooted on stock rom? or another? is the phone even activated? have you tried *228? if that in fact fails, follow this procedure and you should be fine.

if that process helps you, make sure you thank SimsDelt (the op of that thread) for his knowledge and helpful insight, and if you post there, he will infact respond with any issues you will have.
