A SIM card contains all of the information that a cell phone has recorded during use--for example, individual contact information and phone numbers. To copy a SIM card from a cell phone using a 3G cellular network, use a SIM copy device. The SIM copy device is designed to "clone" a SIM card so that the copy is identical to that of the original. There are a number of SIM copy devices available, all operating in a similar and intuitive manner to copy the 3G SIM card.
Straighten a paper clip. Insert an end of the paper clip into the hole on the cell phone next to the SIM card's carrier tray. Push the paper clip into the hole to pop the tray out. Remove the tray. Turn the tray over and catch the SIM card in your palm. Place the tray and cell phone aside.
Place a hand towel on a table. Place the SIM card on the hand towel. Place the SIM copy device face down on the table.
Remove the battery compartment lid from the bottom. Line up the positive- and negative-labelled ends of the battery with the positive- and negative-labelled ends printing inside of the battery compartment. Insert the battery into the battery compartment and close the lid.
Turn the SIM copy device over. Insert the slotted end of the 3G SIM card into the slot on the device. Slide the selector switch on the side of the device to "Copy." Press the push button to start the device working. Text information will appear on the LCD screen of the device as the copy is made. Remove the 3G SIM card from the slot when the text on the screen says that the copying is done.
Slide the selector switch on the side of the device to "Clone." Insert the copy SIM card into the slot on the device. Press the push button. Remove the copy SIM card that is now a duplicate of the 3G SIM card from the device.
