A Flexi-upgrade lets you upgrade your phone at any point after six months to a plan of the same value or more - without having to wait until your contact expires.
You'll need to pay an early upgrade charge, which is calculated daily and will decrease the longer you've had your contract.
Who can get it
You'll need to have an Essentials, Red Extra or Red Entertainment plan.
If you joined through a third party such as Carphone Warehouse, or if you've already taken an early upgrade from another plan, you won't be eligible for a Flexi-upgrade.
