Send a lot of short messages

This should be a problem with the mass messaging software.

That is to say, in the software programming, the judgment of sending number is increased. When the number exceeds a certain number, a dialog box will appear.

There is such a judgment, which makes the software more user-friendly and allows you to think for the last time before sending it, and then make a decision.

There should be two solutions:

One: Look at the software settings to see if there are any options such as canceling reminders.

Two: modify the software program and remove the judgment part. This is unlikely, you must know the source code of the software.

It may also be the setting problem of the mobile phone itself. As I haven't used your mobile phone, I can't make a judgment.

You can do a simple test by sending mass messages directly on your mobile phone without using group software to see if this problem exists.

If there is a prompt, see if it can be changed in the phone settings.
