- Many plans have a Data limit up to which a customer can enjoy seamless speed. On exceeding the data limit the speed gets reduced to minimum plan speed which depends on the original plan speed. This is called the FUP or the Fair usage policy. If you exceed your data limits, you can purchase Flexybytes+ from ACT that give you additional data at your original plan speed on a one-time basis. There is no limit on how many times you can purchase the same.
