Will the charges be prorated if I use the internet on roaming for less than 24 hours?

For U Data Roam 10 and U Data Roam 10 Booster, a flat rate of RM10 will be charged upon successful activation and valid for 24hrs.

For U Data Roam 36 and U Data Roam 36 Booster, a flat rate of RM36 will be charged upon successful activation and valid for 24hrs.
