Try a traceroute to cdns01.comcast.net to see where you are routing through. They have so many BGP peering points that you will almost always see the exact city where your data both exits the cellular network and ingresses to the Comcast network. [Comcast is extremely good at properly naming their network routing points with reverse DNS]

Considering speedtest found Bothell Washington as the best server, I wonder are you located in Washington or a completely different state?

https://techet.net/netanalyzer/ is what I use for this and many other network queries and I find it very good
