Got any leftover data? Don’t worry, you may carry that over to the next month untill 1000GB as long as you renew your plan before it expires!
However, please note that only the remaining data from your baseplan (main quota) can be rollovered. The rollover feature is not applicable to bonus or add-on data.
Data accumulation will only be effective 24 hours after activation and last renewal plan. So, if you renew your package again in less than 24 hours, the remaining data from your previous renewal cannot be carried over to the next month.
