USB-modem based on Android is an integrated feature of the system MIUI, which does not require the installation of third-party applications or obtaining root rights. In this article, we will discuss in detail the process of activation, setting up APN parameters and solving typical problems faced by owners of Redmi Note 8.

The advantage of wired connectivity is not only the speed of data transfer, but also the simultaneous charging of the device, which is critical for long sessions.
