Could this be locked by the network operator so it cannot be removed? Is there a work around?
I have tried to search, but have not found an answer.
My SIm cards seem to have had the option to disable the PIN code disabled. I have tried several different phones. On connecting to the phone network I enter the pin code and it's accepted no problem. But when I try and disable the PIN code lock, it wont work. It either says, not supported, or wrong pin code. I am entering the correct PIN, many many times! I have tried this in Android Kit Kat, GB, Win 6.5 and an old Nokia. Always the same result.
