[quote]Watch While Abroad
Eligible Prime members can also stream selected Amazon Originals titles while traveling abroad--without having to change the country settings for their Amazon account.
The Movies and TV Shows categories in the Fire TV menu change automatically to include Watch While Abroad rows. These rows (e.g. “Prime TV to Watch While Abroad,” “Kids TV to Watch While Abroad,” etc.) show all titles included with Prime that are available to watch while traveling abroad.
To browse titles available to watch while traveling abroad from the Amazon website, go to:
