O2 SIM in O2-locked lumia 820

I have an O2-locked lumia 820 that is not recognising an O2 SIM. I have tried a hard reset but this does not help.
WiFi works fine, and I get reception from same location on the same SIM when it's in a different O2-locked handset

Has the handset ever worked? If not it may be blacklisted

Did you purchase it new or used? If used you may have been sold a blacklisted one that won't ever work in your country.

Are you certain it's O2 locked? Does it have an O2 splash screen when powering on? If not it may be locked to another network.

Is it locked to O2 in your country or O2 in another country? O2 operates in several countries, one locked to O2 in another country won't work with an O2 sim from a different country.
