It depends on the plan you are switching to as follows:
Changing to a higher-level plan:
The change occurs immediately, and the month in which the change occurred is billed at the total of the pro-rated amounts for the previous plan and the new plan [days of use × cost per day].
Changing to a lower-level plan:
Changing procedures are not fully available during the term of the current plan. You first need to cancel the plan during the term of the current plan, and then apply to a lower-level plan after the terms of the current higher plan ended.
- Even if a cancellation is made during the term of the current plan, you will still be able to use the current plan until the term ends.
