How to Replace a Samsung Galaxy 5 SIM Card

A Subscriber Identity Module, known as a SIM card, is a programmed microchip that is placed inside a Global System for Mobile Communication (GSM) mobile device called a cell phone. The SIM card identifies the user to the mobile network that the user subscribes to. Therefore, if you don't have a SIM card, you will be unable to use your phone [source: ATT]. There are various reasons you may want to replace, or move, a SIM card. SIM cards can be switched from one phone to another.
