Without it, you can make only an emergency call of rescue services. The call is free and can be made even with a negative balance.

This is done in case something happens to the smartphone owner. The person who finds it will be able to call for help even when the display lock is working.

This option is activated by the user independently in the security settings.

The so-called “unlocking” procedure of a smartphone takes up to 20 days, and the cost varies from one to 10-12 thousand rubles.
