welcome to the forums!!!!!!
what phone do you have? have you tried to update your prl and profile? it should be in the phone's settings. also maybe call your carrier. it might be that a cell tower is down or something.

Like ocnbrze said, Welcome to the forums

Have you tried reentering your Apn settings and the tested your data connection then. Depending on your carrier usually this information can be found on their website.
