The campaign is intended to promote membership registration for the Cmode service, which enables the purchase of a beverage (Coca-Cola Company product) via a mobile phone. The campaign will be announced through advertising on mobile phones and vending machines. Users can participate in the campaign by downloading a dice game to their mobile phones. Dice start rolling when a call arrives and winners get a giveaway or a coupon that can be used with a vending machine to purchase a beverage via a mobile phone.
