I live in South Korea and my aunt gave me her iphone 12 pro max from USA.
She passed away, so it is keepsake from my aunt.
After I received it, I noticed that there is carrier lock and sim card is from T-mobile.
There are 2 IMEI numbers for each physical sim and available sim.
Due to this lock, my sim was not workable here in Korea.
Although I asked Apple technical support, they informed that it is carrier lock and it must be unlocked by the carrier, then I can use this iphone here in Korea.
Please kindly advise if it can be unlocked by T mobile and can I ask it to T mobile since my aunt passed away who was the original owner.
Thank you.
