How to use an OTT voucher on VuwaniTalk

How South African prepaid scratch-card vouchers work and how to redeem the code in your app to add credit.

What is an OTT voucher?

An OTT voucher is a prepaid scratch card, sold in South Africa, that holds a set amount of calling credit. It is a handy way to buy credit with cash at a retail store rather than using a bank card online.

How to redeem it

• Buy an OTT voucher and gently scratch off the panel to reveal the code.
• Open the VuwaniTalk app and go to the voucher or top-up section.
• Enter the voucher code exactly as shown, then confirm.
• The credit is added to your balance once the code is validated.

Tips and troubleshooting

• Enter the code with no extra spaces, and be careful with characters that look alike (like the letter O and the number zero).
• Keep the scratch card until the credit is confirmed in your balance.
• If the code is rejected or shows as already used, contact support with a photo of the card so we can check it for you.
