My phone was stolen, I have an old phone and sim to use. The SIM is for an old phone (iphone11). Can you help me activate it?

You will need to report it to O2 as you will be liable for any phone use till you do
O2 will then send a replacement SIM with the same number

You can also pop in store with photo ID to get a replacement sim instantly.
This also cancels the old sim immediately preventing any fraudulent use.
