RE: data point - anonymous E.164 number usage

Hi Lawrence, Michael,
Even if you have kind of 'registration', like in Germany, it is of no use. If I buy a Pre-Payed, I have to fill out a form and produce some kind of ID. After some time, I decide to sell the phone to someone called A. This person then decides to sell the phone to a person called B. As the Pre-Payed Cards are activated by a key being printed on that card, noone knows, who actually is using this phone and number. Regarding ENUM, this situation is going to be a pain.

Is the phone activated or any card I bought at the local grocery?
Many thanks,
Rudi
