Problems with texting and calling

Hi!

I have a problem with my phone, I just got it 2:nd hand so I do not know if it worked properly earlier.

I can't call anyone, the phone just disconnects and says "beep beep beep".

People calling me goes straight to voicemail.

I can not send or receive test messages unless it is iMessage.

3G data traffic works properly though, any thoughts? I have restored the entire phone 2 times and the network settings 2 times and it is still the same problem. When I tried to use the SIM-card on my old phone (android) it works as espected.
