Hi, I currently have a Galaxy Ace with Koodo Tab. But I have an unlocked phone with no contract so I would like to use that phone. Can I put the Koodo SIM card on Tab to the new phone? Will it work without me getting charged for extras? Does every phone with all carrier work that way? Like if you put a SIM card (on contract) into an unlocked, no contract phone, is it going to work? Or will I have to pay for possibly "ending" the contract/tab?
