Ping issue

So when I'm in my home wifi which is 40mbps upload and download, valo is at 30-40 ping , Now when i have to play the game with my mobile data hotspot, the ping is a constant 90-100 , my mobile data is like 150-200 mbps download but 10-15 mbps upload, is this the fault of the upload speed or is there any way to fix the 100 ping
