Dual SIM card by SimCardGlobal.com - why do I need dual SIM

RoadRunnerUS

Friends,

I recently found an International dual SIM card on SimCardGlobal.com

Their rates are very cheap, serving like 200 countries and I understand they offer both US and UK numbers on the same SIM card which sound cool. What I didn't understand is what is the advantage of having an additional US number on the same SIM? If I live in Australia and travel to US, it will cost my callers the same to call UK or US number, so why do I need this extra number?

Can someone explain and shed some light on it? Thanks.
