o2 payg mobile number

hi, could anyone tell me how i can get the number of my new o2 sim card if there is no paperwork with it as i have lost the folder it came in. thanks in advance.

Put into one erikson mobile and there is in the phonebook menu - "my number" ;-)

Or you could buy a top voucher and when you top up the phone it tells you the number of the phone you are toppping up ... :)

Call a different phone and look at the caller ID
