@Mitchy1 you will just be charged for the new plan, but pick the proper choice. If you can wait for 4 more days, pick Change on Renewal
Change Now will allow PM to start the new plan now. But the unused days on your current cycle will be forfeited, no partial refund
Change on Renewal will schedule plan change at the end of the current cycle so you won't lose any money. Use this option if you don't need the new features or data now
