New sim with iphone13

[Vix72]

I have received my new iphone13pro today but they have sent me a new sim which I did not request. I want to keep my existing O2 number should I use the new sim or transfer the old sim?

You don't need to use the new sim, just put your current sim in the new phone, and put the new sim somewhere safe just in case you need one in the future 🙂

Thanks for your message - I thought it might be so it works with a 5G phone...?

Yes if you dont need or get 5G where you live I would just stick with the old sim.. If you do want 5G then you need to do a sim swap via the details on the sim wallet.

@Vix72 Here's a guide to do a sim swap: SIM Swap: a mini guide (incl eSim) - O2 Community
