My SMS query shows that there is less than one G, but Xiaomi's own traffic query is16 G. Why?

It is best to log in to the online business hall corresponding to the mobile phone card on the webpage, or pay attention to the corresponding official WeChat account and log in for inquiry, which is more accurate. The short message prompt is actually accurate. Maybe you have 15 G traffic package, which is exclusive and limited to a company or its software. SMS only queries general traffic packets. This is the case with my short message.
