GeoSIM's Dual IMSI SIM to boast UK and US numbers, reduce roaming fees

While we've seen some pretty novel advances in the SIM card space, few have rivaled this in terms of sheer functionality. In a beautiful effort to cut down on roaming charges, GeoSIM has just announced that it's preparing a Dual IMSI SIM that will initially include a US and UK phone number, making it remarkably easy for those who travel frequently between American and the United Kingdom to call back and forth without racking up absurd roaming charges. We can only assume that future cards will enable any two countries (or more, maybe?) to be programmed in, and while we're still not totally clear on what the fees will actually be while using this card, we're kosher for now just knowing they'll be lower.
