Unlock esim on iPhone 11 Pro Max

www.att.com/deviceunlock

If your phone is eligible, it will be unlocked.

Make sure that you acknowledge the unlock request email.

I get a message that my device is blocked by the operator.  while all physical sim work

@MihailRiabokon Are you saying a physical sim from a different carrier works but an esim does not? What does your phone show under settings/general/about/carrier lock?

in the settings there is information that the sim is not blocked by the operator.  But at the same time, when I scan the qr code of esim, I get a message that my phone is blocked under another operator and I should turn to it.  judging by the phone model, I concluded that the blocking is from at & t

in the settings there is information that the sim is not blocked by the operator.

Then your phone is unlocked. Whatever is causing you to get that message when trying to install an esim, it’s not ATT. There is nothing more ATT can do for you.

Found an article with a similar problem.  Perhaps this reference describes the problem better.
