Moving SIM-only account to new unlocked iPhone

[Scottivo]

I have an iPhone 11 Pro, bought unlocked directly from Apple. I have an O2 SIM-only contract. I have bought a new unlocked iPhone 14 Pro from the Apple store. Can I simply take the existing O2 SIM card out of my old phone and use it immediately in the new phone?

Yes you can, but you will need a new sim if you are in a 5g area (unless yours is already 5g).

You can get a 5g sim from any O2 store or by contacting O2 online or by phone.

Thanks for the swift reply MI5. There's no 5G where I live, so I won't upgrade for now.

No problem for you then mate.

Just swap your old sim to the new phone.
