I got a T-Mobile plan that gives a new upgrade iPhone each year. If I purchase a 2-yr Apple care +, can the new phone be covered since it’s on the same APPLE ID? Or I need to cancel the rest plan and buy a new one for the new phone?
You cannot transfer AppleCare from one phone to another but you can cancel it and buy a new plan. See: Cancel or change the payment method for your AppleCare plan - Apple Support

Can my Apple care protection cover a new upgrade phone?
