Glo and Airtel don't have strong network in some parts of Nigeria. It's funny how Glo is an indigenous network yet not serving effectively.
I only used it for a month or so and I stopped due to their bad network. I am not saying they are not good, their services are cool, their data is cheap and durable, how I which they can work on their network strength.
For now, MTN is the best, it's indeed everywhere you go.
Its not how far but how well, Mtn is topping with their good network regardless of them be the last produced amon g this three. Thanks for stopping by.
