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.[Via Boy Genius Report]
ive seen this done before by another company and its a great idea. its a little buggy sometimes. but it brings amazing rates.
Because it's too hard to either carry two sim cards or two phones?
I'd imagine an ideal solution would be a phone setup that would allow text-only on one sim while out of country, while the other one would allow all functions.
That would be nice. China Mobile gives me free incoming and local outgoing texting rates while int'l roaming (suck on that, AT&T users) so that would be my text SIM with a local SIM for actual talking.
It’s a good Idea, but I guarantee local prepaid SIMs will still be a lot cheaper. Also this will probably use a callback system which never works half the time. Also can’t you already do this with a MaxRoam SIM when their system is actually working?
