Can I read short messages?

As long as you use a mobile phone, it is equivalent to completely exposing yourself, because the mobile phone needs to constantly exchange signals with the base station to keep the mobile phone in normal use, and you can use the base station to determine the exact location of the mobile phone user. You can finally determine which street, which floor and which room Ge You is in in Mobile Phone. As for the phone calls and text messages sent by mobile phone users, these contents can also be inquired, but these information will not be seen by internal employees or others, and communication companies will not take this risk.
