International free text and data

The link just brings me to the page with the country field blank, but thanks for checking.  If I type in Italy, nothing happens at all.  Normally when I'm on this page and I type in Italy, it comes up in a box for me to select, and then I get the message that it's not supported, even though I know it is.  It's been this way for months and I don't understand why T-Mobile doesn't fix whatever the problem is.  I've seen numerous posts from people reporting the same problem.
