Good day Nairalanders, there's something I've observed, but want to be sure if it's just my phone that's having issues or it's general.

Each time my data is about to get exhausted, browsing becomes really slow, and sometimes you can't even surf the web. But anytime I switch my airplane mode on and off, the data becomes normal for few minutes and returns back to being slow.
What's really the issue
Btw, I use MTN

Mtn speed has been really terrible last week. Even when my data is more than 80%.

What is really wrong with MTN?
