May I know which prepaid telco is better for sporadic days usage in a month? Say out of 30 days, I may only need to use data for 10-15 days only. Xox or UnifiMobile perhaps? If xox will need additional rm25 to keep it valid annually while UnifiM doesn't right? Im thinking of Digi Next15 initially because i have an legacy digi prepaid however it seems digi next15 is overkill plus rm38 SLL is not known to be offered always.
