hi @WilliamHu if you change mid month using Change Now option, you will lose the money with the current plan's current cycle, there is no partial refund
But if you used up your data for this month, you might have no choice
is there any charge if I change my subscription to a new one with the same monthly payment in the middle of the subscription period?
The full price of the new plan would be due and a new billing/plan cycle would start. Also, there won't be any refund for the remaining time from the old plan. To avoid this, please pre-schedule the change to occur during renewal.
