A Bluetooth modem is a standalone device or an option that allows you to distribute mobile Internet via a wireless connection. This feature is useful when you want to share your traffic with another device that does not support a Wi-Fi connection. For example, a Bluetooth modem has been actively used to distribute the Internet from a smartphone to a laptop.
Before starting the connection, it is important to ensure that the receiving device is equipped with an internal or external Bluetooth module. Also, sharing the Internet from a smartphone may increase battery consumption. The mode is activated on your phone as follows: “Settings” → “Advanced” → “Bluetooth modem”.
And, of course, for correct operation, it is necessary to activate the mobile data transfer.
