On Linux, given an USB surfstick with a SIM card that has a PIN, how can I disable the PIN of the SIM card?

Note that the PIN is known, I do not want to crack it etc, just disable it.

That might depend both on the SIM model and on the modem model. – Gilles Sep 1 '13 at 19:58
If the SIM is removable, why not putting it into a phone and clearing the PIN there? – peterph Sep 3 '13 at 17:20

Setting the pin to 0000 usually disable it.
