Speed problems on cellular broadband connections on AT&T.

[Bolillo 0]

I have cellular broadband through AT&T 4G LTE and a 50 GB limit at which point i'm not throttled, just deprioritized. When I am still within my limit I can get up to 29 Mbps, and after my limit I can get 6 to 9 Mbps depending on tower traffic even through vpn connections. I always connect to a Canada server from Michigan, but whenever I try to watch movies on Kodi I can barely get 1-2 Mbps. Is there anything that I can suggest to fix this problem? Maybe SSL or SSH or a specific settings change like ports, protocol, DNS?

Where is the Kodi server located and what bandwidth does that server have?
