You can't. Paramount probably uses your IP address to geolocate you. The problem is that geolocation through IP is not very accurate. It's typically based on the IP server location, not your actual location.
One good chuckle is with my Comcast service. On my Roku, I get WBBM here in Chicago. On my X1 cable box, I get KWCH from Wichita, Kansas! Most likely because it goes through Comcast's internal network and doesn't get a normal IP address, so it defaults to the middle of the country.
In addition to what andyross mentioned ....
You can use a website like https://www.iplocation.net/ to see where the IP number assigned by your internet provider indicates you are located.
