There a lot of network in Nigeria, some I even don't know and is in existence but the most popular ones are these three (3) : Airtel,MTN and GLO Mobile .These three networks have been serving it's purpose for years. They have been live safer when it comes to needing network but nevertheless if they should be ranked they can be.
If I should rate them , GLo will come as 3rd , reason why is that it's mostly not available everywhere, the network is not everywhere, while you can't see anyone using their network here where I live, some places uses it as their first to come sim. It works perfectly fine with them. Using Glo in my area will be like,
Caller:hello
Recipient:hello
Caller: I can't hear you but if you can hear meππ" he will deliver what he wants to say in the hope that the recipient might hear him.
Now to the 2nd which is Airtel, Airtel has been very good here in my area but that was before because now, in my area you can only make use of it to call, even calls sometimes doesn't connect, the worst part is using it to sub , then you can wash your money washed away
without getting the value for it. It is provoking some times. And the number one (1st) of it all "Mtn " their slogan "Everywhere you go" really is not just mouth , they worked towards . It's going for calls ,for subscription and all. What do they say that a sweet soup requires good money, Mtn as fast as the network is ,as good as it is, it consumes more data and credit than the rest..
There was one day, someone transferred some data to my Airtel number, unfortunately he didn't know I don't use Airtel data, that day I couldn't enter a giveaway here in one of the community, I am looking at giveaway swaying before me but I click and click and it's not reacting.
Aritel and Mtn ,you just have to have the two ,when one goes wrong, the second can't be the same .
