I tried to transfer my old number when switching from bt to virgin but it didn’t work so I just left it and used the new one but this was almost 6 months ago and now I think I need my old number. I was wondering how long bt keep your old number for and if there’s any point trying to get it transferred now?
Do you mean your mobile phone number or your home phone number?
mobile phone number
Did you request a PAC code from BT Mobile, and did you give that code to Virgin Mobile?
If you did not, then its going to be too late now.
A PAC code is only valid for 30 days.
