Добрый вечер! Такой ответ пришел по at&t:
Model: iPhone 13 Pro Max A2484
Status:
We can't unlock your device until all device installment payments have been made.
To unlock, sign into your account to review and pay off your installment plan. You can submit a new unlock request 24 hours after your account shows the device has been paid off. If you pay off your device as part of your regular bill, you’ll need to wait until the start of your next bill period to unlock it.
По этой услуге можно пробовать, она нормально работает?
AT&T USA (США) iPhone все модели только Clean IMEI (с причинами отказа из описания)
Спасибо.
