What if the mobile phone card is degaussed?

The mobile phone card is broken and generally does not degauss. It is estimated that the phone is not in good contact with the card. You can use paper to gently wipe the metal sheet on the back of the card and the contact of the mobile phone, and then plug it in.

In addition, if it is really broken, you should go to the operator to reissue it. Generally, the identity card of the owner of this card should be provided. If you lose your ID card again, you can only reissue it at the local police station with your household registration book. If it's urgent, you can get a temporary one first, and it will be available soon.
