In this guide, we weigh the pros and cons of both options to help you decide which is better for your wallet.

Frequently Asked Questions
Is prepaid cheaper than a contract?
If you already own your phone, prepaid is almost always cheaper because you can take advantage of "Boosta" and other promotional data deals that aren't available to contract users.
Can I switch from contract to prepaid?
Yes, but usually only after your contract term (24 or 36 months) has ended. You may need to give one month's notice to your provider.
What are the benefits of a SIM-only contract?
SIM-only contracts offer the convenience of a monthly bill and often better "base" data rates than standard prepaid, without the high cost of financing a device.
Do contracts have better data rates?
Standard contract data rates are often lower than standard prepaid rates, but prepaid "Personalised Deals" (*123#/*142#) are often the cheapest in the market.
What is a "Hybrid" or "Top-up" contract?
This is a contract with a fixed monthly cost that gives you a set amount of data/airtime. Once that is used, you can "top up" with prepaid airtime, giving you the best of both worlds.
