Would you opt-in for free mobile service if it meant advertisements and survey participation?

The ad-supported model for delivering services for free is not new, but up to now at least, it does have certain limitations. We accept free services like Google, Facebook, and Twitter even though the data mining involved is geared solely to deliver targeted ads, often with creepy accuracy to our moods and tastes.
Mobile service based on such a model does not have much of a presence in developed markets, but it could happen. Once such an idea works in one environment, enterprising folks will look at ways to implement the notion in their own back yard.
With such a dichotomy, one could see the marketing challenge with such a deep user base. Pre-paid usage leans toward inconsistent usage, and the lack of credit card usage prevents consumer data mining to target products and identify other trends in commerce. Still everyone has a cell phone, so how do you get more from your subscriber base?
Candy is an advertising network. Users that sign up for service are given “missions” to carry out. It could be a survey, or checking out a product in the store (or even buying a product). Once the mission is complete, the customer is given a code which is redeemed to reward the account with a “load” (as in re-loading the account).
YOYO Holdings is focused on finding ways to connect with the “next billion” customers, a theme we are sure to see more often as businesses shift more efforts toward these developing markets. Would you opt-in for service like this?
