Quite a common theme...
I travel a lot and I've noticed something similar in Eastern Europe and Asia. In a lot of areas there the fixed-line infrastructure simply isn't up to high speed internet, and so as a result they've invested much more heavily in mobile internet instead as this is a hell of a lot cheaper and easier than upgrading the fixed infrastructure.
It's much more common in a lot of those areas for people to have a home 4G router for example, instead of (V)DSL/Fibre.
So in that sense, it's understandable.
