Everybody using our sim cards would be the best of couse - we have some there lying in the drawer. But simply switching the network seems to be more popular - only one person came to get a programmed SIM card. We will put a legal notice about fine prints onto the registration page. So after all we will probably leave the Auth Token Policy off and let the users enter their IMEI (followed by a registration) before accepting a location update the first time. > The fact that we have the auth-token (or any other) functionality in our > software doesn't mean that it is safe to run it, or that you will hve > legal guarantees about regulatory approval in any jurisdiction! That's clear. But as I configured it some time ago, I thought it would not be a problem, since normally the phones should only try to roam if they cannot establish a connection to their home network. Since they are only one time in our network for about 5 seconds to send the SMS, I saw no problem in there - believing phones try to register back immediately after being thrown out. Regards, Lennart
