But what if a user did not have access to the cellular network by some means. For this there is also a feature incorporated in the application of Wi-Fi sharing which would enable any user to perform similar operations without the use of Internet and instead use the Wi-Fi network of a mobile device and exchange data that are quite larger in terms of size.
