What is going on here?

Just got LTE activated in the last 24 hours on my new Afrihost SIM and Huawei E5372.

This is the sort of latency I'm getting on 4G:

Notice a pattern? It's constantly going high-low-high-low. What is up with that?

I'm also detecting moments of non-responsiveness when browsing to sudden surges of fast loading to non-responsiveness again.

I am in the Lonehill area - specifically where Lonehill and Beverley meet.

Is there some sort of issue? Afrihost website says mobile status is all good.
