Looking at sub-Saharan Africa, I think the key enabler of heterogeneity is the availability of open access national and metro fibre. This is enabling everything from data-only LTE service providers like Smile and Bitflux, to FTTH, to metro WiFi, to TVWS. https://manypossibilities.net/2016/01/africa-telecoms-infrastructure-in-2015/ reveals a positive trend in access diversity, although rural areas remain a challenge.
