Slingshot Mobile

You sure can! We’ll post you a SIM card with all the details you need to transfer your number. It’s easy: just activate your SIM, register it in My Slingshot Mobile, and complete the form to transfer your number.

Any unused data on your base mobile plan rolls over to the next month, for up to 12 months. Handy!

Purchased add-on data will always be consumed first, followed by rollover data, and then the data in your current month’s base plan.

You can purchase 1GB of additional data for $12 and 50 additional NZ and Australia calling minutes for $7 in My Slingshot Mobile.

These add-ons do not roll over and will expire after 30 days if unused.

Our mobile plans are billed every 30 days, so slightly more frequent than monthly. If your Slingshot bill is sent monthly, you may occasionally get two bills on the same monthly statement – although this will be rare.

You can change your plan in My Slingshot Mobile by choosing your preferred plan and selecting “Buy Plan.”

Note: if you choose to have your new plan take effect immediately, any unused allowances from the previous plan won’t be credited. Instead, you can opt to have the changes commence at the start of your next mobile billing period.

Global Roaming is enabled by default, you just need to purchase a roaming pack in My Slingshot Mobile. For information on casual roaming rates, take a look at our mobile rates page.

Our casual rates for services such as MMS, directory assistance and international calls are available on our mobile rates page.
