How to keep your number here https://www.o2.co.uk/help/phones-sims-and-devices/how-to-keep-your-mobile-number

If it is just a simple O2 to O2 swap, popping in store is by far the quickest and easiest way, or call customer service and they will post one out to you Guide: How to find help & contact O2

@rossy551  Does your new phone take a different sized sim than your old phone? If not, you can just use the old sim in your new phone.
