Will mobile data be used when I use the Discover or Store section in the APP?
The mobile data will not be used if your phone has a strong Wi-Fi connection. Without the Wi-Fi connection, the mobile data usage will occur when you enter the Discover section where you can share and view interesting pictures, or the Store section where new YI products are promoted. Extra fees may occur when 2G/3G/4G mobile data is used and will be collected by your mobile service provider.
