Katsina is a Local Government Area and the capital city of Katsina State in North West Nigeria.
Katsina is located some 260 kilometres east of the city of Sokoto and 135 kilometres northwest of Kano, close to the border with Niger. In 2016, Katsina's estimated population was 429,000 with Population of 5,801,584 (2006 census figures). There are 34 Local Government Areas. The state capital is Katsina and the main ethnic groups are Hausa and Fulani.
For most locations in Katsina, there are coverage of the 2G/3G/4G mobile networks, only that service may be disrupted the farther away you go from the city center, and you might occasionally experience network outage for all or some of the mobile phone service providers in those remote areas of the city. Different networks tend to be more stable and reliable in different locations of the city at different times.
A travel plan to Katsina should probably consider possession of multiple SIM cards, preferably for all the mobile service providers, since you can't tell which will be more stable and reliable at a time in your location during your visit. And if you will risk not having any of them, you might be better off not risking the MTN network, because, from indications, it seem to perform well than the others, though its rates may be high and its offers and services might be stringent, but you are less likely to be concerned of erratic voice and data connection compared to others.
Airtel is another service provider which is fairly satisfactory for all you might need to connect to the world, including rates and network stability. Of course, Glo (or Globacom) boasts of fast network speed for internet browsing activities, only that you might not be able to enjoy the privilege in some locations. And 9Mobile usually also performs well in internet browsing speed too but not without locational limitations, plus that data rate is fairly higher.
