Post [Q] SGS2 Cant text or call issue

Hi guys
I have a really annoying issue with my galaxy s2. It seems to be stuck on emergency calls only and will not let me send texts, call people, etc. I have tried everything- restore stock firmware, factory reset, repair apps and nothing has worked. My IMEI number is not null and it matches the one on my phones box. I dont know what else to try so any help would be very much appreciated
