Assalamu Alaikum. This iPhone 11 of mine was brought from abroad. I have used it for about 2 years. I have used the phone with great care. The phone's battery health is 86%. I let my younger brother use the phone for a day. He opened his own Apple ID on the phone but now he cannot remember the password. So I am forced to sell it. There is no problem with the phone. You can use it by bypassing.
