I got free data with the 'Freeway by Syntonic' App.

Great for kids. E.g. sponsored data use for Clash of Clans.

Hi All,

You can get 'sponsored data' opportunities by Downloading 'Freeway by Syntonic'. This is where certain apps give you data to use for their apps (for example, on Pokemon Go, Clash of Clans, SnapChat etc). They also have 'data rewards' options which instead give you data to use on anything by downloading certain apps.

I was able to get 500mb of data last week. It is only on certain networks- but it is most of them. Check it out
