Iphone won't receive texts/calls?

I can send texts and go on internet tho. If somone tries to call me it goes right to voicemail. I have tried restarting it and also turning it off and on. I also tried reseting the network and nothing worked.

Try cleaning your sim card, (wiping), blow in the sim slot.
If that don't help completely reset the phone from itunes,
If that doesn't work then your phone just gave up on you.

Try putting your "date and time" on automatic update. It happened the same thing my phone and i saw my time was off by a few minutes and it screwed everything up with calls and texts. I updated the time and it fixed the problem

Sounds like you didn't pay for your phone bill. That can happen.
