I think internet cafe's are pretty old school everywhere now. Anecdotally, much of the developing world leapfrogged the US on mobile/fintech. People had low end smart phones and banked with their phone carriers 5+ years ago in East Africa.
Latest anecdote (this week) is not seeing internet cafe's in Belize and government PSA's say to contact them on whatsapp.
That said, Facebook makes their money in rich countries.
