This seems pretty cool, so it's free slow cell service in exchange for watching a video ad every hour, with optional prepaid plans for higher speeds/no ads.
It does seem that your cellular is only active for an hour after you last watch an ad, which is unfortunate if you want to receive notifications throughout the day.
