Sim Card Reader And Pin Lock

[fox256]

if i put my sim card into the reader whilst my sim was locked with pin code
do i have to unlock the pin code first on my pc

before i can edit or read any phone book entries

or is the sim card automaticly unlocked when inserted into the sim card reader

also can you change pin code without knowing the original pin code

thanks for all help in advance

Yes, you cannot access the contents of a blocked SIM card until you unblock it, by providing a valid PUK (Personal Unlock Key).

That is only possible if you know the PUK. You will have to enter an invalid PIN several times, in order to deliberately block the card. Afterwards you can reset the PIN (i.e. unblock the SIM card) by providing a valid PUK.

Note that if you provide an invalid PUK several times, the card is permanently blocked.
