I want to change my iPhone carrier

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

Your original carrier policy applies. Contact them to make sure you met the requirements and ask them to unlock it.

Your original carrier must unlock your iPhone - if they choose to do so.

Posting personal or sensitive information on the internet is not wise.

I will repeat:

”Your original carrier must unlock your iPhone - if they choose to do so.”

Contact them.
