phone – What happens if an incorrect SIM card PUK is entered 10 times?

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.
What happens?

  • 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?
