Slingshot Prepay Mobile FAQ

I have been charged twice for my pre-pay plan on the same invoice. Why?


This can be a little complicated to explain, so bear with us.

Essentially Slingshot mobile is charged every 30 days. Slingshot broadband is charged each calendar month.

So just occasionally you can end up with two mobile bills in a calendar month, one at the very start, and one at the very end of the month.

You have still only been charged once every 30 days however.

Make sense? We hope so.


I can’t purchase any more top-ups or complete a plan change. Why?


All Slingshot mobile plans have a hidden monthly top-up limit imposed on them to ensure that customers cannot be surprised by large mobile bills.

The limit is set to a value that no customer should reach through reasonable use, but if you complete a large number of plan-changes or add-on top ups for a month you may find that you are unable to make any more purchases through the various self-serve options.

If this happens and you need to continue topping up, just give our friendly support staff a call on 0800 89 2000 and they will be able to increase your limit for that month and maybe even help you change to a more suitable plan.



What happens when I use the included minutes or data in my mobile plan?


If you use more minutes or data than you have included in your Slingshot mobile plan, then you will need to purchase a top-up add-on to continue using these for that month. Alternatively you can wait until your base mobile plan renews at the end of its 30 day period.

We have two add-ons available:

  1. $12 – 1GB NZ data add-on
    • Unused data from this add-on expires after 30 days
  2. $7 - 50 NZ and AUS calling minutes add-on
    • Unused minutes from this add-on expire after 30 days
  3.  $15 Cash Allowance, drawn against to pay for ad-hoc usage such as MMS
    • Unused allowance expires after 6 months


How does my carry over data work?


Slingshot mobile plans utilise carry over data, with the exception of the Ultimate Plan. What this means is if you don’t use all of the included data in your monthly plan, it will carry over to the next month.

Carry over data is given first priority on your usage; therefore you’ll not start using your current month’s data until any remaining data from previous months has been used. Carry over data from each monthly plan period is valid for 12 months before it expires.



Are any mobile services unavailable on Slingshot mobile?


Most text and calling services will be available to Slingshot mobile customers; however there are a few exceptions to this. 0900 and Txt to Park services are unavailable on Slingshot prepay mobile. Services such as MMS require purchase of a Cash Allowance to draw on.

How do I activate my Slingshot SIM card?
