How to send messages regularly?

If you need third-party software, take Tencent Mobile Manager as an example:

Baidu search downloads "Tencent Mobile Manager" (or other mobile phone management applications). After downloading, install directly.

Connect the mobile phone to the computer through USB cable, turn on the "USB debugging" switch in the mobile phone at the same time, and then run "Tencent Mobile Manager". The program will automatically search and install the driver matching the current mobile phone type.

After the installation is completed, open Tencent Mobile Manager, switch to the Application tab, then enter Android SMS in the Application Search input box, click the Search button, find the corresponding application in the search result list, and click the Install button to install the application on the mobile phone.

Then run the "Android SMS" application in your phone. Switch to the Tools tab and select the Timed SMS button.

Click the "Add Timed SMS" button in the opened Timed SMS box window.

Then in the "SMS Editing" window that opens, enter the receiver's phone number, sending date and SMS content, and finally click the "Send" button.

Then the message to be sent will be found in the "timed message box" and will be sent automatically when the time is up.
