How does OPPOr9 import mobile phone contacts into SIM card?

Because SIM card contacts can only save name and phone information, and do not support rich information such as avatar, SIM card contacts cannot be displayed in ColorOS3.0 system. You can import SIM card contacts into your mobile phone in the following ways:

Version 1 and ColorOS 3.0, enter settings-phone book-SIM card contacts-and you can choose to export from SIM card to mobile phone or import mobile phone contacts into SIM card;

2. For other versions, enter the phone book-three points in the lower right corner-import/export.
