Ultra-Low Cost Handset segment.
The Emerging Market Handset Programme has, as its target, the expansion of the mobile phone use in developing Countries.Research estimates that in the region of 80% of the world's population have wireless coverage, but only 25% of people use mobile services.As a consequence of the two phases of the project, they managed to obtain the production of a handset for less than $30.
Certainly, the achievement is controversial: undoubtedly selling the handset is going to produce profits, and multinational companies do not act for charity.
However, I would say, if the criteria of the project are really customer aware, which I did not have the time to check in depth, it is a good initiative.
Furthermore, on the same site, I found a document on micropayment systems experimented in Philippines, South Africa and Kenya, but it's late and I'm too tired to read it all.
