If you lose your phone one day, the person who finds your phone cannot open your phone with the password, but can steal your money through your SIM card. After taking out your SIM card and putting it into his phone, the person can log into your e-wallet account and steal your money.
Currently several domestic e-wallets and accounts only require a one-time verification code (TAC / OTP) to be entered when logging in. As long as the other party gets your SIM card, he can know your cell phone number and log into most of the accounts you use to log in with your cell phone number, such as e-wallets. Once the other party gets the TAC / OTP, he will be able to perform most of the transactions and cause serious money loss to you.
Here we suggest you all set the password in your SIM card, so that even if the other party gets your SIM card, he can’t use your SIM card to get TAC / OTP smoothly without the password.
The way to set the SIM card is very simple, that is, enter the phone’s settings, and then enter the SIM card option to set the password. The first time you set the password, you need to enter the SIM card preset password, usually 1234 or 0123, and then every time you restart the phone, you need to enter the SIM card password to use the SIM card.
