Netflix Gains Offline Playback for All Streaming Plans
You just need to click the download button on the details page for a film or TV series and you can watch it later without an internet connection. All the downloaded content are stored in My Downloads. Netflix mentions that downloading and streaming consume similar amounts of data.
However, the content is limited right now so not all the content are available for download, but Netflix says most streaming series and movies are available, with more on the way.
The new Netflix Download & Go feature is included in all plans and is currently available for phones and tablets on Android and iOS.
