Of the two 3G iPad carriers, only AT&T offers dedicated international 3G data plans. Much of Europe, along with other parts of the globe, use the same GSM network technology that AT&T does, but that’s not so much the case with Verizon’s CDMA network. (Remember, all iPads work wherever there’s WiFi.)

If you and your iPad plan to pop across the pond to visit London or attend a business meeting in Berlin, you may want to get a plan and micro-SIM card from a wireless carrier in the country you plan to visit.

If that’s too much to bother with, AT&T does offer its own international plans to keep you connected. Be warned, however, that its prices are astronomical compared to the company’s relatively low, low U.S. network prices. For example, a mere 50 MB of international data within a 30-day billing period is $25. There’s no unlimited plan, so if you’re a heavy Internet user, the maximum plan is 800 MB of data for the month—at a whopping 200 bucks (and you thought the currency exchange rates were crazy!).
