Most smartphones have a built-in function that allows you to share the mobile internet connection with other people nearby. Acting very much like a traditional WiFi hotspot, mobile internet connection sharing turns your phone into a hub – authorised devices can then connect to your phone and share the data connection.
This “mobile hotspot” feature is particularly useful when your friends cannot get a reliable connection to their mobile network. Or when you need to get online with your laptop really quickly while “out and about”.
