I’m moving from giffgaff to o2 and requested a PAC code from giffgaff, filled out the form for o2 to have number carried over.
This morning my old giffgaff sim lost service and by noon my o2 esim as well.
It is now well past 6pm and still no service, which is when the service should be kicking back in according to o2s faq page.
I messaged o2 live chat and they insists the swap will happen today. The number showing up in My o2 is still the temporary number, and I’m stranded without any number for calls and texts.
This can happen with a failed eSim so if it's not back on by tomorrow (after rebooting phone), get a new eSim from your local O2 store or ask O2 to send one out to you.
We have had quite a few similar posts since yesterday @Dapotato
