I use this phone myself. I have been using it for a long time and it is very good. The phone's charge also lasts well. I am selling it because I need money.
The phone will run one SIM.
Update:
Sometime Face ID is gone.
There are no other problems.
You can check it as much as you like.
I use a SIM in the phone. Then if you want, I will give you my NID card.
Battery health 100%.
The loudspeaker has turned off.
