about cell phone locked to special sevice provider

I want to know if there is any cellphone locked to some special sevice provider. This kind of cellphone can only accept the sevice provider's sim. Could you tell me the locking principle or algorithm?

I would think that the one that figures out that Zillion dollar answer would be the god of all gods in the cellfone industry. One that ensures that not one other is able to unlock any and or all wireless....are u wit me?the presidents of all presidants(grammar error) the best of the best what can I say/ I would have to say that wireless today is at a place of great challenge. Lotsa unlockers * Imagine.... one that is able to defy all those odds/ operative word ALL
