“Regarding Upgraded: Free wireless calling

So does this mean that I could carry my wireless router outside the country and set up my own US Domestic phone number in Japan?”

Good question. In theory, it’s designed for your use only in your home or in another fixed location in the U.S. But it might work anywhere, sort of how Vonage phone service can be plugged into any broadband connection if you know what you’re doing. (I can’t really speak to the specifics of Vonage, but I’m told that’s how it works.)

I’m looking into my phone’s compatability with the routers first, but I may take the plunge. If I do, I’ll be sure to report.
