Case Analysis

If a mobile phone is lost and the SIM card is not reported immediately, criminals can easily remove it and insert it into another phone to receive verification SMS messages, which poses a very high risk. This is because registering for quick payment with a bank card only requires an ID number, bank card number, and SMS verification code to complete.

Security Recommendations

1. Set a PIN code for the SIM card; the PIN code must be entered to use the number after restarting the phone or changing to a new phone.

2. Do not store sensitive information on the phone or SD card, such as photos of ID cards, bank cards, work documents, etc., to prevent misuse by criminals in case the phone is lost.
