How to Restore a Rejected SIM Card

Dust on a SIM card contributes to its rejection.

A SIM card is a small chip composed of circuits that stores users' data. This information is used by telephone companies to identify the phone. Most smartphones require SIM cards. Sometimes a SIM card is rejected and stops working. This does not mean that the SIM card is broken, but it is an indication that a minor error has occurred, and the card is not being read properly. However, you can restore a rejected SIM card.

Instructions

Restoring SIM Card Function

1. Turn your phone off to prevent interruptions.

2. Remove the battery cover, the battery and the SIM card. Most SIM cards are located under the battery in a small slide-out dish.

3. Grab the slide-out tray and gently pull it so that the SIM card comes out. Grab the edges of the SIM card and gently remove it from the tray.

4. Inspect the SIM card for scratches, cracks and dust. If there are cracks, you may have to get a new SIM card.

5. Blow softly on the SIM card to remove any dust, or wipe it with a clean cloth. Blow into the SIM card tray to remove any dust.

6. Place the SIM card gently on the slide-out tray. Replace the battery and the battery cover and turn on the phone. The phone should reboot correctly, and the SIM card will be recognized once again.
