you must have WIFI to access the internet in order to download apps, books, music, and games.
It wouldn't be worthwhile to buy any tablet without having access to a wireless internet connection. You could start it up and it would function, but the software apps require access to the internet to be able to work well. Tablets are mostly for web-surfing, Netflix, music, and little games, most of which come from the internet. If you don't have wireless internet, you can buy a wireless router and hook it up to your wired internet, or you can buy a portable video or mp3 player or inexpensive laptop instead.
No, you do not need internet access to use this tablet. You do need internet to access the app store(s) and SOME apps require internet access.
