Samsung is one of the leading manufacturers of cellphones. Some of these phones are unlocked, and others are programmed to work on specific networks. Each phone comes with a SIM card, which holds data and account information. These SIM cards may become lost or stolen, or you may want to simply change your provider. In either case, you can replace your SIM card.
