OnePlus How to enable or disable SIM card lock
OnePlus 3919By default, the SIM card is protected by a PIN, which makes unauthorized access almost impossible, since the SIM card is automatically locked after three incorrect PIN entries and can only be unlocked again by entering the PUK number.
If desired, the SIM lock can be completely deactivated if the password and PIN entry is considered annoying, for example, because an additional screen lock has been set up on the OnePlus smartphone.
However, it should be noted that a disabled SIM lock provides all the data and access to the SIM card, even if it has been inserted in another device.
