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.
