Advantages of super sim card
First, SIM shield: put the U shield into the mobile phone card.
People who often use mobile phones to transfer money and remit money are certainly familiar with U-Shield, but U-Shield is shaped like a USB flash drive, which is not only not portable, but also easy to lose.
SIM shield puts the traditional U shield into the SIM card of the mobile phone, without carrying extra hardware, installing drivers, plugging or unplugging, and triggering at any time. Moreover, SIM shield adopts state secret chip and PKI asymmetric encryption technology, which has the same security level as the second generation U-Key, and can effectively prevent criminals from forging or copying, thus avoiding the risk of funds being stolen due to information leakage.
Second, SIM authentication: you don't need to remember the password when logging in.
Now SMS verification code has become the most commonly used method to verify identity and protect our transactions and property security, but is it really safe? According to network security experts, SMS verification code is not unbreakable, and SMS Trojans and phishing monitoring can easily break through the verification system.
The SIM authentication function in the mobile super SIM card is to interact the authentication message with the SIM card application, and use the encrypted data channel for transmission, so that the content cannot be cracked.
