Possibly a faulty sim

did you get this from O2?

Is there an expiry date on the packaging?

If You need to call O2 then choose any of the options, fraud etc
Everything is taking longer due to the lockdown. Call centres and social distancing means limited staff to handle all the queries. Patience needed I'm afraid.
