I've got an old O2 PAYG sim card which I'm going to put with a phone I'm selling, but I don't know it's number and don't have any of it's documentation. Is there any way I can find out what it's number is?
It doesn't have any credit on it so I can't phone another mobile, short of phoning O2 from it is there anything I can do, like with Vodafone sim cards pressing something like #*100# brings up that sim's number?

Call 2425 and click 1 then 1 again. itl repeat your number to confirm your buying a bolt on. Just hang up then

Thanks Greggy, got the number now!

Though when I try to call it I get the message 'it has not been possible to connect your call'. I've had this sim a little while and not put any credit on it, could it have become inactive? It's still showing a signal and connected to 2425 no problem - or will it not accept incoming calls until there is some credit on the sim?
