When I click on free SMS or phone message in Yixin, the phone address book cannot be displayed. What happened?

If the address book only shows some numbers. Because the current free SMS and telephone message functions are only for domestic users, special numbers (such as the beginning of 400 and 95) and foreign numbers are not displayed by default; If all contacts are not displayed, please confirm whether the phone has turned on trusted email software or allowed emails to access the phone's contacts. (For example, Xiaomi mobile phone: please find Security Center-Authorization Management-Programs-Email-Open Trust, ios Settings-Privacy-Address Book, and then open the email).
