A Guide on How to Clean a SIM Card

A subscriber identity module, better known as the SIM card, is a chip inside your phone that contains all your personal information. If it catches a bit of dust, your phone may not be able to read data properly. That can be frustrating.

However, there are certain things you can do to clean your SIM and make sure it works perfectly. Are you wondering how to do that? Let's look at some steps to help you clean a SIM card.

How To Clean a SIM Card?

Before you start cleaning your SIM card, you need to get a dry microfiber cloth that helps remove any dirt or debris.

If the SIM card is extremely dirty, you can dampen a cotton swab using ruing alcohol and gently wipe away any accumulated dirt. Allow the SIM card to dry before you reinsert it completely. Wondering how to do all that? Here's how to make your SIM spotless:

Removing the SIM Card

First, turn off your mobile phone. Removing the SIM card while your phone is turned on can potentially damage its internal components. You might also end up damaging the SIM card itself.

After that, locate the SIM card and take it out. The placement will depend on your device type and model. However, it's usually on the right side of the phone. 

Every phone is different. So, it is easy to remove some SIM cards, while it is hard to remove others. If you have to use a SIM ejector tool, be mindful of the instructions so you don't damage the SIM card or your device.

Cleaning Your SIM Card

After removing the SIM card, you can use a cotton swab or an eraser to remove the dirt or dust. Gently wipe the eraser or cotton swab on the gold chip side. Don't exert too much force, and clean the SIM card using light strokes.

You can then wipe the card with a lint-free and dry microfiber cloth. Don't apply cleaners or bleaching agents to the card or the cloth. The dry cloth will remove any dirt, oil, and moisture.

You can also use rubbing alcohol at this stage. The alcohol will help to remove oxidized spots. You can use a cotton swab dampened with alcohol and gently rub it against the gold chip on the SIM. Gently stroke the swab until all the oxidation is gone.

Sliding the SIM Card Back

After you've cleaned your SIM card, you'll have to insert it back. Make sure it is securely back in its place on the SIM card tray before you push it in. If you took it out from the phone's back, you'd also need to put your battery back in place.

You can also consult your device manufacturer's manual if it is hard to reinsert the SIM card. The manual gives the exact instructions you need to follow.

After reinserting the SIM card, turn on our phone and see if it's communicating. If you clean the card properly, your phone will work without any problems.
