I almost understand callback, but am not sure if I have it right. Could you go over it, for a thick-headed ludite?

Normal callback (Icelandic SIM): dial destination number; you will get a message on the phone such as call not allowed; a few second later your phone will ring and you answer it; the destination number you dial first will ring; you should be charged only if the call connects -- that is you let it ring until you connect.

Callback World double callback: EVERYTHING above PLUS (or but you are dialing your CBW number, not the final destination number) so when you get to the last point where you answer the [first] callback, you let it ring once and hang up again. CBW will call your phone back. Answer and at that point you dial the TRUE destination number.
