Glasskuter made the same suggestion above C:\Windows\System32\Drivers\etc\hosts It looked exactly as the one he posted (no T-Mobile).Check you hosts file for an entry blocking that website.
C:\Windows\System32\drivers\etc\hosts(the file does not have an extension, so you'll need to pick a way to view it, Notepad works just fine, but you'll need to allow elevated privileges for Notepad to be able to edit it).
Don't post the contents here - but see if the T-mobile domain (
t-mobile.com) appears anywhere in there. If it does, then you should really, before doing much of anything else, run a full scan on your system, because there is no reason this entry should be in there.
