You need to use your old sim or do a sim swap to use the new one Guide: Sim Swap: a mini guide 2017 update

I've sold my old phone along with the SIM in it - do you know what I can do?
You should never do that.
The sim is your contract and anyone could now use it to run up a big bill.
I hope you've called O2 to report it by now?
