I have XIAOMI Redmi 6 phone, model M1804C3DG. Android version: 8.1.0, kernel version: 4.9.77+ .
There is no options in the menu to remove or change the pin of the sim.
I have enabled developers options too, but no options are displayed related to the pin of the sim.
If I insert this sim in another phone (ios operating system), the options to remove or change the pin is displayed in the menu, and it works: this means the sim works properly.
How to remove the pin, using this XIAOMI Redmi 6 phone?
Thank you
