It would take time as in many countries people don't have access to internet especially in villages So it will not be as easy as we are thinking. As many of the villagers don't use internet and if they have access to internet it would be very costly and the speed of internet would not match the criteria.
I know a few people who've been to Africa. Mobile phone coverage is insanely good in some very surprising places. That's why M Pesa is thriving. It's often not a case of lack of internet, it's more to do with hardware. Smart phones are getting cheaper all the time. Soon they'll push out the old school phones as they have in first world places.
