How to unlock your iPhone for use with a different carrier - Apple Support

• Apple can't unlock your iPhone for use with a different carrier. Only your carrier can unlock your iPhone.

You need to contact your Carrier.

Or do you need the PUK code?, See this Apple article: Use a SIM PIN for your iPhone or iPad

What did your cellular carrier say when you contacted them?

If it is locked to a different carrier, only that carrier can unlock your iPhone, if you are eligible. All you can do is listed in this support article:--> How to unlock your iPhone for use with a different carrier
