How to Download My SIM Card to a Computer

GSM-based cell phones use SIM cards to store information pertinent to the phone, including the device's contact information, user interface and, depending on the settings of the phone, voice mails and stored contact data. If you want to back up the information of the SIM card onto your computer, download the SIM data directly onto any computer system.

Connect the USB end of the SIM card reader into a USB port on the computer. It does not matter what USB connection port you use to hook up the computer equipment.
