Gets the job done 64 Gb card is necessary for full download of Wikipedia. If you download via http  you will also likely have to change your browser's default download location to the SD card  which is WAY harder to do than it should be. On galaxy note 2 I had to use the default Samsung internet browser  because Firefox and Chrome don't even give the user control over download location  for ease-of-use cloudy-cloud-cloud mobile platform reasons I guess.
