How to read it
When you check a Mobile Proxy USA line, the ISP is a US mobile carrier, because the address belongs to the carrier's pool and is shared by many real phones through carrier-grade NAT. Location is shown as the metro or state rather than a street. Two things will give an account away: the browser time zone disagreeing with the IP, and a WebRTC candidate that exposes your home or office address. You can fix those in the browser profile and then check again.
