O2

Bit of a long shot this, as I suspect there are not many members who will even remember the HTC S740 Rose; but I like to keep old faithfuls going, as emergency phones. Anyway, I have used the S740 with 02 many years ago and after a few years with Ora...

Is there a list anywhere of useful numbers eg 1720, 4444 etc. I am sure I had one with my original SIM but the new one doesn't have any of this info and I can't find it on the O2 site. Any help would be appreciated
