I’m not into marketing, but as Sprint user I get free data roaming almost everywhere in the world. I believe T-Mobile does as well. It’s advertised as up to 3G but is usually better. In fact, it is often better than hotel WiFi in places like Germany. If your cellular provider still charges extra for international data plans, it might be worth sniffing around for another provider. I basically have the same cellular service i have at home anywhere in the world for no extra cost.
