Visiting from content I read by @reonlouw a fellow South African, some great ideas you mentioned above in first world countries where data is cheap or free.
Yes we have a few areas where people would be able to use these apps to make more, sadly out in rural areas it would be an expensive task!
Jotting down a thought, something that has bothered me for some time, sitting in an area where a ADSL line has hardly worked since May, have a backup of WiFi dependent on the day as to signal availability.
How do you sell an idea to people who really don't have or are unable to get around local regional problems?
There are a number of plans in the works that will change that. There are mesh networks being set up. Also, both Branson and Musk are sending up satellites starting in 2019 which will blanket the planet.
You are about to see a lot of competition forming in that area over the next few years, especially in the rural areas.
Appreciate your answer, it has taken quite some time. Living suburbia I personally know our connection has gone downhill, how rural people make connection, both difficult/expensive.
A couple of years ago Google promised rural cafe hot spots for people to be able to obtain a signal, never heard what happened after that. Talk no action?
Everyone has a phone, most use What's App or similar connections, for 'cheaper' data connectivity, Kenya and Nigeria sound to be more advanced in this.
Exceptionally high un-employment among school leavers to age forty, education into technology now is what is required foremost.
