At UNDO, we don’t believe in waste. What you don’t use, you take with you to the next month.

How it works:

– At the end of the month, your unused data, call minutes and SMS are automatically rolled over to the next month.

– Your rollover balance is always used first, then your new monthly bundle.

– Whatever remains after the next month expires — rollover therefore only applies for one month.

You can see your rollover balance in the UNDO app or My account at https://wsc.undo.be/?lang=en under YOUR RATE.

Important to know: in case of cancellation of your subscription or a number transfer to another operator, the rollover balance is lost. It cannot be refunded or transferred.
