Today more and more establishments offer free public Wi-Fi. Indeed, if your establishment is in a zone where the 4G is good, your users will prefer to use their 4G rather than paying to enjoy your charged Wi-Fi. On the other hand, you can choose to offer a charged Wi-Fi if your establishment is in a black spot, or an area where 3G and 4G are nearly non-existent. Your users will have no choice but to pay for Wi-Fi if they want to go on the internet. Finally, you can also choose to offer free access up to a certain limit. the user will then have to pay.
