Old phone number

[Sophielou]

I am trying to sort out an old phone and I can’t remember the o2 number I used for it. Can anyone help with how I can find it

Hello @Sophielou

If you Text NUMBER to 2020 – it's free to send this text and we'll reply with your phone number.

However if you have Credit or allowances in that Sim Card you can try Text another number and you'd find it out if it is still active.

Hi, the O2 number will be with the SIM not the phone, if you have a SIM in the phone and it is still active you should be able to view the number, what phone is it?
