I don't know what exactly I did with my phone, but it now it shows "SIM Disabled". I as told that I need to replace my SIM, which is OK, but I need the numbers, stored in it. Is it possible to do something or they are lost forever?
try a Cingular store for a SIM reader. it will be able to copy the numbers from your old SIM and put them on the new one. I dont know what phone you have, but depending on the phone you can put the numbers on your phone first and then transfer them to the new SIM
