Absolutely! If you have used all of the included minutes or data in your base plan, you can continue to top-up additional data or calling add-ons to suit your usage.
Please be aware that all add-ons purchased will appear on your next Slingshot invoice and any un-used minutes or data will expire after 30 days.
Another thing to consider if you are one of the cheaper mobile plans is that it might be more cost effective to just upgrade your monthly recurring plan to one that includes more data or minutes.
There is a hidden limit on the amount of top-ups and changes you can make per month; however it is high enough that most customers shouldn’t hit this through regular use.
