How to unlock your mobile phone

A small number of mobile phones we sell are locked to the One NZ network.
These phones can be unlocked, so they can be used on another mobile network - with that network's SIM card.
This kind of lock is often referred to as a "network-lock".

How much does unlocking cost?

  • There is no charge to unlock a mobile phone that was bought from us more than 9 months ago.
  • There is a $30 (incl. GST) fee to unlock a mobile phone bought less than 9 months ago.

Here's how you can unlock one of these network-locked phones.

Steps to unlock your One NZ mobile.

Simply click the green button below, and follow the steps to get the unlock instructions for your particular phone.
A link to your instructions will also be sent to the email address you provide.

Before you start:

  1. Have your IMEI number handy. To find your IMEI number, enter *#06# on your keypad, or look under your mobile phone's battery.
  2. The non-One NZ SIM card needs to be placed in the locked One NZ mobile phone to enter your unlock code.
  3. If your phone was purchased less than 9 months ago you’ll need your debit or credit card to pay the unlock fee - you cannot use One NZ Prepay credit to do this.

Unlock your mobile phone

Do you have a PIN-locked SIM card?
This is a different kind of locking and it happens when you've entered the wrong PIN too many times.
If that's the issue you want to solve, then see how to unlock your SIM with a PUK code.

Important things to know

  • Network unlocking is only required if you plan to use your One NZ mobile with another provider's SIM card (including overseas networks).
  • We cannot guarantee that an unlocked mobile phone will be compatible with another specific network. This is because different networks may use different technologies and mobile frequencies. Please check compatibility requirements with the destination network provider.
  • We can only help with unlocking One New Zealand mobile devices purchased from an authorized One NZ retailer that hasn’t been tampered with, 'jail broken', or flashed.
  • A One NZ mobile must only be unlocked by following our unlocking instructions. Attempting to unlock a One NZ mobile by any other means (including by entering an incorrect code more than three times) may cause the phone to become unworkable, and void the applicable warranty. Vodafone will not be liable for any damage that may occur.
  • No guarantee can be given that our instructions will work for phones that have been 'jail broken' or had the manufacturers' settings tampered with.
  • Standard Prepay Terms and Conditions apply.
