How to stabilize ping in 4G?

Question

mobile connection

Not only the speed, but also the ping is better than in 3G, but the jumps are up to 60 ms (the ping itself is 90-150, it rarely jumps up to 200).
Ping suits, but that would make it more stable.
If you have something to advise about the reduction - also lay out =)

Answer 1

you can limit the maximum speed, how to do it specifically in your case, I don’t know
, tried such feints on Mikrotik - it helped

Answer 2

no way
because it still depends on your neighbors
