Unless you tell o2 otherwise your contract will just roll over and continue on.
Did you take the contract with o2 or through a 3rd party (Carphone Warehouse, MobilePhonesDirect)?
If o2, you will start paying just the airtime.
If a 3rd party then you will pay the same amount and you would be better off moving to a sim only.
