I think what you are doing is very important thing but it's not scalable to 2.5b people.
The biggest problem for those 2.5b people are:
- Availability of network infrastructure. It starts with whatever network backbone and ends with either mobile internet or wifi network. In most cases there is no business case to build out this kind of infrastructure as there is essentially no way to recover investment unless its subsidized by government or world bank or something.
- Availability of electricity. There is many place that simply has none or it's very unreliable. It has twofold influence - its hard to build infrastructure that will work and people have no place to charge phones/laptops
- The actual price of devices. Even if you are talking about advanced feature phones or low end smart phones (laptops are way out of price range for most of 2.5b people) its still expensive. There is all kind of schemes with operators subsidizing the device over few years but it's bring arpu to very low numbers making it hardly viable business.
Edit. I actually lived in Georgia during the "fun" time, late 80s - early 90s. Good luck.
