“Scott, Clay, and everyone else wondering which of the 18 iPad models to get, here's the lay of the land. The Verizon and AT&T iPads are similar in the United States. They can both connect to Wi-Fi networks when you're at home or work, and when you're on the go, they both connect to 3G cellular networks for data, just like the iPhone. However, things change when you go outside the US. The Verizon iPad uses the same CDMA technology as the Verizon iPhone, and thus has very limited capabilities when you leave the country. The AT&T/GSM iPad, on the other hand, is unlocked and has a SIM card slot. Most countries have GSM providers that you can purchase data from.” - × × ×
