Xiaomi 1 1 How do I need a password to cancel the communication phone?

You can go to phone settings > personal > access restrictions, and cancel the restrictions on calls and text messages according to the prompts.

This is because mobile phones encrypt calls and messages. The method of canceling encryption is as follows:

First, click "Settings" on the phone desktop.

2. Then select the "Apply Lock" option on the phone's setup interface.

3. Click the gear symbol in the red box in the upper right corner of the page after entering.

Fourth, finally turn off the switch in the "Application Lock" column.
