There are 2 typesof iPads that you can buy, regardless of size/capacity. iPad "with Wifi" and iPad "Wi-Fi + Celluar". "With WiFi" means that you can only get on the Internet or download apps via the App Store when you are at home on your home's Wifi Internet (or another place that has WiFi internet, such as at school, work or a Starbucks). "Wi-Fi + Celluar" iPad, in addition to Wi-Fi, comes with the ability to access the Internet via cellular technology just like your cellphone (e.g., iPhone, Samsung). An iPad "Wi-Fi + Cellular" that has a paid plan from your wireless provider can access the Internet anytime and anywhere, regardless of Wi-Fi availability.
