DataRewards offers a solution that allows users to access the internet for free through advertiser-sponsored data. If a user tries to access the internet but has no data balance, they will be redirected to a captive portal where they can browse freely by watching video advertisements from sponsors. This provides value to both users, who gain free internet access, and advertisers, who are able to promote their products and services. DataRewards also works with WiFi providers to implement similar models, displaying advertisements to users after a certain amount of free browsing time to allow them to continue online.
