How to bring your own number to One NZ How to bring mobile number to One NZ.

Submit your details to bring your prepaid number to One NZ.

Before starting, make sure you...

  1. Have activated your One NZ SIM card.
  2. Have the One NZ SIM packaging, with its unique details.


Awesome! Your number is being switched over as we speak,

What do I do next?

It can take around 4 business hours to complete the number transfer (sorry – we are unable to process these requests in the weekend). In the meantime, keep your 'old' (non One NZ) SIM in your phone and keep using it until you can no longer make or receive calls / txts - this means your number is now with One NZ.

When you're all set up, make sure you jump into My One NZ and check out the details of your new plan.

If your old SIM is still working after 4 hours call us on 777 and we'll get it sorted.

While you're waiting

Get ahead of the game and download the My One NZ App while we are transferring your number. It's super simple to set up and is the best way to keep track of your usage, top up and get access to your Prepay Deals. This is where you can also change to another plan or design your MyFlex plan each month.

Download my One NZ app from your app store.
