Re: cant send or receive text or calls on moto x
Nextel with a Moto X? Good trick since a) Nextel doesn't exist any more (unfortunately - it was handy, and Motorola came out with some fantastic phones for them) and b) it used iDen, a protocol the Moto X doesn't have.
If you mean just Sprint, bring it to a Sprint store - it sounds as if your account is set up (provisioned) wrong.
