Phone is locked to a different network from that which the sim is on.
If locked to O2, guide here Guide: Unlocking an O2 phone to use a different SIM card
or contact the network that has locked it.
Or you are trying to move an esim which isn't supported by O2, so you need a new esim pack.
May be possible from your MyO2 or from any O2 store. Take photo ID.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
