To top-up your credit voucher one needs to scratch the smaller panel with a coin to reveal the 14-digit voucher number and proceed by calling 125 or by using the key sequence explained further below.

Method #1 - Voice Voucher top-up system
Call 125 and follow the instructions given to you by the automatic answering machine. The machine will be confirming the entry and also providing you with useful information as to how much credit has been topped up, validity and the cost of the last call made. 

Method #2 - USSD Key Sequence
Perhaps this is the fastest and most effective way to top-up. All that needs to be done is to type on your mobile phone the sequence as follows: *125#Voucher_Number# followed by pressing the call button (usually green button). This will confirm on-screen that the top-up has been made and will also provide you with the current balance, last call cost and time-window.

Method #3 - Web Top-up
Log onto your self-care by clicking onto the myredtouch link. Create a password for your mobile account and you're ready to top up. Just select the denomination you wish to top-up with and enter your card information. An SMS will be sent once topped up as well as a fiscal receipt will be forwarded to your supplied email address.
