| | Re: Using Blackberries in Japan?
Japan's networks, as are Korea's, seem to be coming around or maybe he devices just include those frequencies these days. Not sure which. Most of the newer models will work, but it really depends on where you are and what carrier. Many of the older models will not.
My advice would be to check it out with people stationed where you will be. I was in Japan and the Far East way before the cell phone was "invented", so can't really help. If you are going to be there for a couple years, you might consider getting one from a Japanese carrier via the base exchange service.
Might try using our SEARCH feature and search on "Japan" and see what you find.
