Ok every time I try and call of my phone it says. I have tried reinstalling the frimware and all that did was lose my apps. Tried doing a different firmware and tried rooting all the same results. The phone is definitely unlocked and unblocked as while I was searching google I came across one of those secret codes to show the status of the locks and all 4 of the categories were unlocked. I have tried a batterry pull and tried cleaning the Sim card. Also just in case this helps when I g into Settings>Call>Additional Settings it says 'Network Or Sim card error'. However the Sim card is perfectly fine.....so anyone have any advice? I have taken a few screenshots just in case they help.
I found the code again and took a screenshot of the it too.
