How to Fix Your SIM Card Address

A subscriber identity module (SIM) card is a unit located within cell phones that keeps track of phones numbers and other contact information. This card can be switched from cell phone to cell phone and still retain contact lists (provided the service provider remains the same). In the event the SIM card is damaged, there are several ways to go about trying to fix it. However, if a few simple steps are followed and the card is still malfunctioning, it would likely be better to take the cell phone and card into the place where they were purchased --- or contact the service provider.

• 1

  Turn off the cell phone and take out the SIM card. Turning off the cell phone can be accomplished by locating the "Power" button, or on some phones, the "End" button. Once the phone is off, remove the card, typically positioned underneath the phone's back cover near the battery. Occasionally, SIM cards can be accessed on the side of the phone.

  Check the card. After removing the SIM card, take a close look at it to see if any damage has been done. Usually, signs of damage --- such as cracks or broken pieces --- are evident. In some instances, the card may only need to be removed and put back into place for it to function properly.

  Re-insert the card. If there are no obvious signs of damage to the SIM card, re-insert it carefully and turn the phone back on by pressing the "Power" button. If it still appears to be malfunctioning, make sure the card has been re-inserted properly, usually with gold bands facing down.

  Clean the card. If removal and re-insertion of the SIM card does not fix the problem, you can repeat the first step by removing the card and cleaning it. Sometimes dust will keep the card from functioning properly. Apply a small dose of rubbing alcohol to a clean cloth and wipe the card. You can also blow out any residue in the area in which the card is inserted back into the phone. Once the card dries, re-insert and turn the phone back on.

  Contact the service provider. If the SIM card still isn't working after removal and cleaning, it is time to call or visit your service provider, and find out additional steps, or if a new SIM card is needed. On the bright side, many service providers keep your contact list information backed up on their computer systems for use in the event your SIM card cannot be repaired.
