- These changes only apply if you're changing your account details or transferring a One NZ mobile number to someone else. If you're selling or giving away your mobile, but keeping your SIM card with your number, you don't need to let us know.
- Remember, if you're transferring ownership of your On Account mobile, you may be liable for early termination charges on your contract. For more information, visit your nearest One NZ store or call us from your One NZ mobile on 777.
- If you have moved your number from On Account to Prepay or Prepay to On Account using Payment Flexibility you will be unable to do Mobile Number Change or Change of Ownership in the future.
