Can I get other people's information by connecting my mobile phone to other numbers?

I can't. Changlian function has an envelope message, which encrypts the conversation content, so you don't have to worry about others seeing it at all and won't reveal your privacy. Changlian is a full-scene audio and video call product based on distributed technology launched by Huawei, which can realize audio and video calls between mobile phones, large screens, speakers and other devices.
