What if the mobile phone card is degaussed? If the information in the card is gone, can I charge it magnetically?

First of all, we should confirm whether it is degaussed, pull out the card and wipe it, then put it on to see if it really doesn't show up, or go to the business hall and let them have a look. If it is degaussed, it can't be recharged. You can only change the card again, and the number remains the same. It seems that I have to pay, but the contents are gone.

If you have a phone number, you can print a call list and write it down one by one.
