Turn the phone to mute, etc. SMS alarm should pay attention to the following points:

Adjust the mobile phone to prevent sending and receiving information from being exposed. When editing the case message, remember to write down the location of the case and so on.

Send a short message to 12 1 10, preferably adding the last three digits of the area code after 12 10, so that the police can lock the alarm position more quickly.
