My Xiaomi has turned on traffic, but my mobile phone is not a 3g card. I can't display the page on the online music of the application supermarket and Xiaomi, so I can only buckle up the webpage. why

Hello, because by default, when you use data traffic, it is not recommended to use programs that take up a lot of data traffic. This is to prevent you from disconnecting wifi and using a lot of data traffic without knowing it, resulting in high phone bills. The latest system has been changed, and it will be reminded in non-wifi state.

Thank you for your support and wish you a happy life!
