What is a Wingle?

A wingle (like the MF79U) is a USB modem with built-in WiFi hotspot. It plugs into USB for power and internet, then broadcasts WiFi so multiple phones, tablets, and laptops can connect wirelessly. Regular USB modems (MF831, MF833) only provide internet to the computer they’re plugged into.
