One NZ Mobile FAQs

Can I keep my number if I move to One NZ?

Yes, number porting is a standard part of switching — we handle it as part of the process.

What's the difference between prepay and postpay?

Prepay: pay before you use it, no lock-in. Postpay: monthly billing, often with a longer-term commitment.

Will I lose service while switching?

No — porting is designed to be seamless, with your existing service running until the new one activates.

Do you charge for comparing mobile options?

No, our advice is free.
