Well, thats reality. Sometimes the mobile telco hotlines are so overloaded, you cannot even tell them that your phone was stolen. (Talk about service-but you get what you pay for) In germany, there is some list, where every cell phone can be entered with its IMEI-number (thats like the MAC on an ethernet card). So theoretically you simply enter them and make them useless for the thief. But its too much work for the telcos, so they tell you they cannot, their computer systems are down, or the list is overcrowded and no more entries can be made (there was a discussion on .de usenet some year ago, IIRC, and they stated that the list indeed was very big and no-one really cared for that), etc etc. It is simply some work, that they don't get paid for, have some personnel that is not trained for other tasks then saying: Ok, I'll send you some prospects... So there are some insurance companies offering policies, but we all know the attitude of insurance... Bottom line: The telco does not want it, because it is work, and they don't make money with it. It would be technically able to enter the _individual number_ of a cell phone into a database (which already exists), rendering stolen cell phones useless immediately. They will be simply denied upon log-in to the tower.
