Your contacts and text messages stored in the SIM can be recovered, transferred, edited or backed up with a SIM card reader and a PC. The SIM card reader is a USB device. Be sure to get one that comes with PC software. Install the software, put your SIM in the reader, enter your PIN code (the same one you use to unlock your cell phone) and you have access to your contacts and text messages as you would any files on your PC. You will not be able to get other information, such as your subscriber information, pictures or music. If you never used your cell phone PIN code or didn't even know you had one, call your operator and they can probably tell you what it was.
Two other options: 1. Connect your cell phone to a PC with either USB or Bluetooth, that also lets you save your media files 2. Get a backup service from your operator who can help you do all of these things at their store. Consider signing up for a phonebook backup service with your operator. This way if you lose your phone you can call customer care to restore your phonebook.
