Sim activation

Can’t seem to activate my new sim

@Kerry8 Is this a sim that came with a new phone? If you have the sim from your old phone, and it's the same size, use that for the time being. If the sim that came with the new phone is 5G and you're in a 5G active area, you can do a sim swap: https://community.o2.co.uk/t5/How-to-Guides/SIM-Swap-a-mini-guide-incl-eSim/ba-p/1060675

If you're not in a 5G area, just carry on using the sim from your old phone.
