iPhone 13 changing to G5 SIM card

[Kate17]

Hi, I am an existing 02 customer and setting up my iPhone 13 upgrade. I want to keep my existing number and changing the SIM card. Does the new SIM card carry my existing number or what do I need to do to keep it? Thanks

You can either use your old sim, or if you want 5G then do a sim swap from your old sim to the new one. Guide: Sim Swap: a mini guide 2017 update
