iPhone 12 Pro Max
Regarding the carrier, Apple cannot lock or unlock a phone. Only the carrier can do this. Apple is not involved, so this is not an Apple support issue.
The SIM card that you are using is not supported by the carrier that you are trying to use.
Who is the carrier that you want to use?
What happened when you tried another new SIM card from the carrier?
