They are the worst telecommunication company in Nigeria. It's really a shame that it's the Network company of Nigeria but they can't give a good network service for their users. I have stopped using their services a long time ago.
Well, I do not live in Nigeria, so I am not sure about the services offered by these companies. However, I think that you can always switch or use another mobile carrier if you are not satisfied with the services. There are around four to five network carriers in my country.
