Prepay Plan Terms and Conditions
‍‍

*Unlimited data: Maximum data speeds, Fair use and Mobile terms apply. Unlimited voice calls and TXTs to standard NZ and Aus numbers, landlines and mobiles, placed while in New Zealand only (e.g. no short codes or MMS/PXT). Personal mobile phone use only.

All Mighty Mobile plans are Prepay. The full amount of each plan must be paid upon activation, renewal or purchase of a voucher. A Mighty Mobile SIM card must be purchased before a Prepay plan can be activated. SIM delivery can take up to 14 working days, after which you can activate your Plan. 100 MMS are included to standard New Zealand mobile numbers. Calls, SMS & MMS to non-Australian international numbers, special or premium numbers (eg. 0900, 018) data calls and usage, video calling and roaming services are not included. Additional add-on packs (when available) must be purchased separately in order to use premium services like roaming and international calls.

Upon activation, all plans are set to Auto Renew by default. This means your Plan will automatically renew 24 hours before its expiry and you authorise us to take payment of the charges payable for the renewal of your plan using the payment method details that you provided to us upon registration. You are able to cancel and/or disable Auto Renew by going to your Mighty Mobile account at accounts.Mightymobile.co.nz/login, select the Billing Details tab and click Remove Schedule.
