• PUK CODES
The PUK and PUK2 codes are 4- to 8-digit codes that also usually come
from your service provider along with the SIM card. The PUK code
unblocks a blocked PIN code, and the PUK2 code unblocks a blocked PIN2
code.
If you block your phone, contact your service provider. When you enter the
PUK code given by your service provider, the phone prompts you to enter
and then confirm a new PIN code.
• SECURITY CODE
Note: The default security code is 12345. Nokia recommends that
you change the default code immediately.
