Switzerland Sim Card When IPhone 3G Subscription Ends Can You Then Use Any SIM Card?

When iPhone 3G subscription ends can you then use any SIM card? - switzerland sim card

I think buying the iPhone 3G in Switzerland but live in Switzerland, leaving in 12 months in Denmark, I'll buy the iPhone 3G and 12 month subscription when it expires and cancel my contract with Orange, Swisscom and the use of a SIM card (SIM card) in the Danish language? Or if I buy the iPhone and has been released without a subscription, so you can use any SIM card?
