I know that if an incorrect SIM PIN code is entered three times, it is erased. There is no longer a valid PIN, but the user can configure a new PIN with PUK.
But when the incorrect PUK code is entered 10 times, it is no longer possible to unlock it.
Is everything on the SIM card erased or only the PUK code?
Is the SIM card blocked if the user enters 3 times an incorrect PIN, then 10 times an incorrect PUK code when attempting to activate PIN protection by PIN?
Is it possible to unlock the SIM card?
