Carrier says to go to Apple Store to unlock my iPhone
Mint Mobile, who I have been with since February when I also bought a new-to-me, refurbished iPhone 13 mini, said my phone is not able to activate a new eSim. They suggested I go to the Apple Store for Apple to unlock it sooner than Mint can. Online, Apple forums suggests that only the Carrier can unlock my phone. Which is true?
