HOW TO UNLOCK US RESELLER ACTIVATION POLICY

Follow the instructions here: https://support.apple.com/en-us/HT201328

If it still doesn't work, call AppleCare. They can tell you whether it's actually unlocked or not.

If it is, then Apple should be able to help you. If it is not, you will have to work it out with T-Mobile.

The ONLY source for unlocked iPhones in the US is directly from Apple.

I ATTACHED CARRIER UNLOCKED PROOF

A: A screenshot of a chat session with a support drone from the carrier does not constitute "proof".

B: Even if it did, it's not relevant here.

What did Apple tell you about the lock status of the phone when you spoke to them?

Yelling at me with your Caps Lock on is not going to make things work faster, better, or even at all. The fact you paid off the total amount does not matter. You made the error of purchasing a phong at Best Buy believing it is an unlocked device you could use outside the US. It isn't. As KiltedTim stated earlier, only Apple sells unlocked phones in the US. That is not Apple's fault and Apple does not unlock phones. I still don't believe there is a fix based on my understanding of the Flex policy. Even if the phone is unlocked from the carrier in the US, it cannot be used outside of the US.

From what I understand, even if you can get a flex policy phone unlocked, it cannot be used as an unlocked phone outside of the US. I remember reading this before here on the forum, but I cannot seem to find the reference to it any more. That could very well explain why you are experiencing the problem with the activation outside of the US.

Please READ my response above.

Apple does not have the legal right to remove the carrier lock. Only the carrier the device is locked to can do that.

Again, attaching something here is not going to change things. Apple cannot help you.

If you activated it with a US T-Mobile SIM, the phone is now locked to T-Mobile. They are the only ones who can unlock it.
