I purchased my Phone overseas with a plan with it. Will I be able to use your SIM cards?

Some phones are "network locked" meaning it can only use it with a certain plan. You have to check whether it is "network locked". If it is then you will not be able to use any other SIM cards except for the binding network cards.
