I have a problem with Nairobians who base all their arguments on the fact that Nairobi is Kenya.
Nairobi is not Kenya. It just happens to be a part of Kenya.
Some of us have access to Safaricom only.
My relatives and friends have problems when they visit for other service providers are not available and when they are, users have to climb trees or go to the roof to access their respective service providers.
Perhaps then you could rephrase your poll with options that inquire what service providers are available and the region one is based.
For me, Safaricom it is for their is no other to compare with.
