You can't even get cash from your bank without the bill numbers being recorded anymore.
They certainly haven't gone that far over here and I seriously doublt that US banks have the technology, or the time, to record every used bill that passes backwards and forwards across their counters.
Back to the OP the number of mobile subscriptions is a poor measure as PAYG SIM cards are so prevelant. I know that there are two old SIMs somewhere in my house with credit on them as well as my phone and the dongle for my laptop.
