Do I need a pac code from o2 to keep my current o2 number

[Lottie49]

Hi

Sorry I'm really clueless.

I have a new o2 phone with a nano sim and my old phone has a normal bigger sim. I've put the new sim in my new o2 phone, and I've activated the new sim, I think. I now need to do something to keep my old number. I think I need a pac, is that right? How do I get a pac? Do I need my old phone to get a pac?

thank you!

If you were with O2 before, you need to do a sim swap Guide: Sim Swap: a mini guide 2017 update

If coming from a different network you need to text from your old sim to get your PAC Guide: How to get your PAC [June 2021 Update] 

Once you have that, fill out the form here https://www.o2.co.uk/help/device-and-sim-support/how-to-keep-your-mobile-number

Thank you!

I just need to wait for sim activation to happen?
