My 4 can't get calls

[Revlefty]

So I wake up today to the phone ringing only to find out that I missed about 10 calls before that. The phone won't ring it just goes straight to voicemail with no sign that it rung. I also can't receive text messages. But I can make calls and text messages with no problems. And everything else works fine.

Any ideas what could be wrong?

In one sentence, you say that the phone rings, in the next, you say it doesn't. Which is it?

It rung once, nothing before or after.

I've had the issue before on my 3G back in the day. Is your iPhone jailbroken?

To get a temporary fix on the issue you have to dial a GSM code.

That's what I think it is too. It's possible that you have accidentally dialed one of the GSM codes for Call Forwarding. To cancel, go to Settings>Phone>Call Forwarding. The GSM code to cancel is: Turn off all Call Forwarding: Dial #002#. Press Send.

I'm pretty sure now it's an ATT problem and not a phone problem. I was playing around with it a little more today and I swapped sim card with my gf's iPhone 4 and my phone worked fine with her number in my phone, it could get calls, texts and the "waiting for activation" thing on the face time went away. And nothing changed with my number in her phone. So I guess their is a call to ATT in my future.

I agree, that's why I posted what I did in the previous post... Did you check those things?

Call forwarding was off, but I tried the code and got some errors;

error performing request
no network service

it says "setting deactivation failed" and it says the same thing for;
voice call forwarding, voice call forwarding, data call forwarding, fax call forwarding, sms call forwarding, and a few others

Heck, I hoped that was it....Time to call AT&T I suppose.
