What is the smart card in Xiaomi's mobile phone for? How to use it?

Add the above figures to understand. The mobile smart card is also called multi-number mobile phone /sim card replicator/mobile phone card replicator/mobile phone replication card/mobile phone magic card. Simply put, the number information on the 1- 12 mobile phone card is copied to a special replication card, which can accommodate 6- 12 mobile phone numbers, can be erased repeatedly and can be switched between numbers. Examples of specific functions and usage are as follows: 1. A mobile phone has multiple numbers. If you have more than two mobile phone cards, you can save the burden of tying two mobile phones or even multiple mobile phones. Now, tying two mobile phones is not a symbol of status, and two codes for one mobile phone is the best choice. You can switch calls at any time. 2. One person * * * Use: If you have a monthly card, an ip business card, or a mobile phone fee that can be reimbursed, you can make several copies and use them with your family and friends. 3. Phone book data backup: You can copy the phone book and short messages in the mobile phone card to the computer as a backup through the card reader, edit the phone book and short messages on the computer, and copy the phone book and short messages to the copy card. 4. For young people who love to be handsome, when you have a SIM MAX multi-code card, where can you go, where can you save, where can you show off, where can you show off! And change the number directly online, without shutting down and reopening! For drivers who often run long distances, SIM MAX can provide you with super-fast convenience: you don't need to stop, switch at any time and answer the phone at any time. Why bother? 6. Solve the inconvenience that the SIM card of advanced imported cars such as Mercedes-Benz needs to be removed and put on the hands-free mobile phone equipment: copy a set of SIM cards and put them on the hands-free mobile phone equipment, which can not only answer calls with the same number, but also add the numbers on them.

The answer is not easy. I hope I can help you. Please help me adopt it if you are satisfied. Thank you.
