phone number of an O2 sim card

[Oldphoneuser]

I have an old O2 sim card of the size that fits in older phones, not iphones.  I want to use it in an old style phone but I don't know the number that goes with it.  Numbers on the sim card are 89441, 10064,70477,2965, 3GP 10.  Is there any way to retrieve the phone number associated with this sim card?

It will be useless now due to age and disconnection status.

You'd be better off getting a new sim that will work.

Thanks for the reply.  That's kind of what thought, but thought I'd give it a go.

If you've got the old 'phone and the old SIM, pop the SIM into the 'phone and call yourself. 

You never know what might happen !

Nothing as it will have been disconnected years ago.

But, I don't know the number that goes with that sim.  Suppose I will have to look up the numbers of the various old phones my family members had and try them all until it rings, if it rings. Thanks for the thought anyway.

@Oldphoneuser If the sim has been disconnected and out of use, the account would have been closed and the number most likely would have been reassigned. You're probably wasting your time.
