I recently came back from abroad where I didn't use my phone, only to connect to wifi. I came home and put my sim into another phone which worked fine before and now I'm having issues with my network. Nobody can call me, mobile connection keeps tapping out and going to emergency calls only and when sending messages it comes up as "error 0". It comes back sometimes and my FB messages come through but it goes again shortly after. Please help. Currently the mobile connection is on "E" .
