You have important contacts on your phone's SIM card, and they are at risk of being lost unless you can back them up to your desktop computer for safekeeping. A USB SIM card reader and its accompanying software can copy information stored on a phone's SIM card (i.e. your contacts and text messages from your phone) to your computer. A SIM card reader also is a handy tool for moving information to a new phone.
