Unlock instructions for the Nokia Lumia 635
- Switch the phone off
- Insert non-One NZ SIM card
- Switch the phone on and enter SIM card PIN code if requested
- Wait for the SIM unlock UI to open
- Type in the SIM unlock code (20 digits) and press "enter"
- Phone should now be unlocked.
Note: If the "SIM network unlock PIN" is entered incorrectly more than 10 times, the phone will display another "unlock SIM BLOCK" prompt screen and ask for an unblock pin. Please contact One NZ on 777 again to receive this unblock pin. After the unblock pin is entered correctly the phone will still be locked but now the "SIM network unlock PIN" prompt screen is brought back.

Please note: We cannot guarantee that an unlocked phone will be compatible with another network.
This is because different networks may use different technologies and frequencies. Please check compatibility requirements with the destination network provider.
Important: Do not try to guess, or make up, your unlock code.
If our instructions are not followed carefully and you enter an incorrect code multiple times, you may lock your phone completely.
