My contract runs out in April for my Apple Watch.
I don’t want to upgrade, but I do want to keep the watch on contract.
When do I let you know? How much will it cost.
I know you won’t reduce price until I actually tell you to.
You don't do anything. These contracts don't just end. After the min. term they just carry on at the current price on a rolling month's notice basis until you explicitly cancel or upgrade.
