Frequently Asked Questions
Is it cheaper to buy data or use airtime directly?
It is always significantly cheaper to buy a data bundle. Out-of-bundle airtime rates can be as high as R2 per MB, while bundles can cost less than R0.10 per MB.
Can I reverse a data purchase?
Generally, once you have converted airtime to data, the transaction cannot be reversed. Always double-check the bundle size before confirming.
How long does converted data last?
The validity depends on the bundle you choose: from 1 hour and 1 day to 30 days or even longer.
Can I convert airtime to data for someone else?
Yes, most networks allow you to choose "Purchase for another number" within the USSD menus after you select the bundle you want to buy.
Why did my airtime disappear even though I had data?
This often happens if you have "Out-of-Bundle" billing enabled and your data bundle expires or runs out while you are still using the internet.
