How to send a barrage message? What's the effect of screen SMS?

When you say screen-popping SMS, you mean flashing messages, that is, after the mobile phone receives the SMS, it turns on the mobile phone, and people appear on the page, but they will not enter the SMS app, nor will they be saved in the mobile phone, so you need to take screenshots and save them yourself.

Generally, the content of this flash message is within 70 characters, which is very short.

However, this kind of short message does not take the regular short message channel of 106, and does not support the reply content, but some people use it, but the overall usage is not as much as that of 106 short messages. This kind of short message generally doesn't need many attributes. You can consult and try. If you feel good, you can use more.
