How can i reset my security code for my nokia ceo168 with imei 352366/06/76

SOURCE: Resetting Security Code

SIM pin code:
This is a pin code that locks the sim card until you enter the correct code. This protects your account, even
if your sim is put into another handset. To reset it, you need the PUK code:
Pin Unlock Code (PUK)
If you miss key (or forget) your SIM pin code, and enter the wrong one 3-5 times in a row, the SIM will lock up, and you’ll need to enter the PUK unlock code to release it. You should ask your Network Service Provider for this code when you need it. Don’t try to guess it, because after a few wrong guesses, the SIM card will be permanently disabled.
Phone Security Code:
This locks the handset, as opposed to the sim card. You can also set some handsets to only accept a “new” sim if the phone security code is entered. To reset it, you need the Master code code:
Master Reset Code
Sometimes known as the Master Code, this allows you to unlock a handset if you have entered the Security Code wrongly too many times.
Which is the one that you want?
