If you lose your phone one day, the person who finds your phone cannot open your phone with the password, but he/she can steal your money through your SIM card. After taking out your SIM card and putting it into his phone, this person can log into your e-wallet account and steal your money smoothly.
Several domestic e-wallets and accounts currently 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, they can know your cell phone number and log into most of the accounts you log into with your cell phone number, such as e-wallets. Once the other party has obtained the TAC / OTP, he can perform most of the transactions and cause you serious monetary loss.
Here, we suggest you to set a 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 successfully without the password.
The way to set the SIM card is very simple, it is to go to the phone settings and then to the SIM card option to set the password. When you set the password for the first time, you need to enter the SIM card preset password, usually 1234 or 0123, and then every time you restart your phone, you need to enter the SIM card password to use the SIM card.
