How to Recover a Bad SIM Card

By Cleveland Van Cecil

SIM cards are small chips that slide into your cell phone. The SIM card collects information that is input in the cell, such as phone numbers and other contact information. Many phones offer a backup service for the SIM card as part of their software. If you didn't back up and your SIM card malfunctions, you may need to recover the data. SIM cards are sensitive chips. A card that is cracked or severely damaged will not be recovered.

Things You'll Need

  • Cotton swab
  • Rubbing alcohol
  • SIM card reader

Step 1

Clean the contact of the SIM card if it is dirty using a cotton swab and rubbing alcohol. The contact is the metal portion on one side of the SIM card. Rub the cotton swab along the gold contacts and allow to dry.

Step 2

Download the Data Doctor Recovery software from the CNET website in the Resources section. This software is free.

Step 3

Insert your SIM card into a SIM card reader. SIM card readers are available from many electronics stores. Plug the SIM card reader into your computer's USB port.

Step 4

Run the Data Doctor software and search the SIM card for information by clicking on the magnifying glass icon. If information is found, save the information by clicking on the "Download" button.
