Subscriber identity module (SIM) cards are removable and portable memory chips used in cell phones to store and manage personal contacts and related information. The contents of a SIM card may include phone books, text messages, call logs and even media files. Depending on how you use and store this phone information, the amount of data will vary. The direct way of viewing the contents of a SIM card is through an actual cell phone containing the card. You may also find out what is on a SIM card by transferring the information to your computer through a SIM card reader.
