t-mobile Home Internet - Location Issue

Believe it or not, that's up to you. I've provided you with sufficient explanation and technical buzzwords whereby you can verify or disprove what I said. In the process of doing that you'll educate yourself on how to counteract this behavior. If you want to start at the beginning research what an IP address is (and isn't); from there move on to CGNAT (consumer grade network address translation) and how your public IP address is shared with other customers who may or may not be in the same geographic region as you are. An entire book chapter would barely be enough to explain all of the technical details involve with geo-location issues. 

One thing is certain however; you didn't sign up with me. I don't work for T-Mobile. This is a peer-to-peer (i.e. customer-to-customer) support forum and not direct T-Mobile support. T-Mobile's presence here is one of moderation to help ensure healthy exchanges.n

I do agree, however, that T-Mobile should make this better know up front and it should be included in its Open Internet Policies publication which is required by the FCC. You'll find that link at the bottom of the page and might be surprised by some other things that weren't disclosed except by a reference to that document in passing when you signed up with T-Mobile.

But I'll stand by my suggestion to complain to those who are really responsible for this issue - content providers who rely on faulty geolocation database that use an IP-address for anything other than its intended purpose. Complaining to T-Mobile wont fix it and it's not simply limited to T-Mobile.
