How to send text messages to other people's mobile phones and also to my mobile phones?

First of all, you can check the detailed list online. This is relatively simple. Methods: You can drag your boyfriend to the business hall to modify the initial password for handling business, so that you can log in to his account, or take his ID card to the business hall to print out a detailed list. You just want to know if he's having an affair with anyone else. Secondly, post his flying letter.
