WiFi is a wireless technology that allows devices to connect to a network, usually the internet.
If browsing on the internet using a mobile signal seems intermittent or slow, then WiFi can be a real help to get access to the internet in more places.

4GEE WiFi uses EE's mobile phone network to provide you with an internet connection. This means you're connected wherever you have EE mobile coverage.
