Does what it says on the tin. I only use it to call one number in the US from my mobile. I dial the 020 access number which comes out of my O2 minutes and then I dial the number in Chicago.
Basically, it works. Penny a minute to call USA and the rest comes out of my minutes. Would be better if it didn't come out of my minutes, but I'm not sure how that would work.
Only thing they're missing is itemised billing.
