The great thing about Slingshot mobile is that there are no overage charges for calling! If you use all of the included NZ and AUS calling minutes in your plan then you would need to purchase a 50 Minutes NZ and AUS calling add-on to continue making calls.

There is also no risk of large international calling or roaming bills on your mobile, as you need to purchase the $15 Cash Allowance add-on in order to make calls to international numbers. Global Roaming is enabled by default on Slingshot mobile.

Please note that 0900 numbers and Text to Park services are automatically blocked when you're activated on Slingshot Mobile.
