Transferring old number

[Anneesa1]

So I'm new to O2 and have done SIM swap.I gave the PAC online to O2 when purchasing but my old number still hasn't transferred over yet.
The service on my old SIM turned off on Thursday and I need to use my old number.
How long will this take ?

Can take longer because of the weekend

Having the same problem as well, I got the phone on Thursday and they said it would be a day at most.

You should both have received text messages with a date of transfer

If you haven't then fill the form in here again

Advice from an O2 Guru regarding a way to get through:

If you call 202 or any number in the link, when it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.

Press 2 for Everything Else

Press 5 for More Options

Press 7 for Anything Else which will put you though to an advisor.

Press Upgrade, Lost/Stolen or Fraud if you have to.
