One of the few departments Nigeria has really improved is network speeds , I've been outside the country and when I come back home one of the things I usually miss is fast download speed but surprisingly that is changing very fast.
It used to be that a couple years ago in places like Lagos,Akure the highest download speed I've gotten was like 2mb/s.
But nowadays even In less industrialized areas like Oyo,Akure I get sometimes 20mb/s download on Airtel 4g which is actually crazy even considering worldwide standards.
My highest is mtn 4g in Lagos -33mb/s

Here is my current speed in a less industrialized part of the country

I've actually gotten as high as 265mps in Lagos, Which was very higher than my average speed when I visited the UK years ago.
That is impressive
