it will only pick up verizons market with in the usa .... just like we cant use a iphone on verizons network. its a blessing and a issue that they have a sim card to use cause when you land overseas in idea it should just be able to work but you are also paying there per min fee vs if you could get a better deal with a local overseas company with there own sim .... also ..... keep in mind its pitched that blackberrys will need some sorta data service of 30 or 45 bucks a month on verizons network ... gotta pay to play idea..
Right in the statement. "It's when going abroad that the Storm breaks new ground, though. The Storm supports all major overseas GSM and 3G networks. It's quad-band GSM, which gives you full GSM roaming even in Latin America. It also has HSDPA 2100, so you get full 3G data speeds in Europe and Asia. Verizon has roaming agreements already in place that support those 3G networks, and Verizon does not charge extra for 3G roaming; it's the same rate as GSM/EDGE data. The Storm 9530 even works in Japan and South Korea. A SIM card comes with the Storm, so it's ready for all this global action right out of the box."
