why haven't karoo gone down the same route as airnet and nextgen to provide better coverage
That's what i wonder.
Probably because they don't want to invest any money in it, after all up to now we have had no choice on our ISP so like it or lump it...

Soon they will have to do something to remain competitive or shut up shop altogether...

don't wish people to loose jobs but it's only a matter of time for Karoo unless they start looking to improve their service...
