What does the green exclamation mark on the envelope of Android SMS mean? Let's be professional. Amateurs make a detour. Thank you. I can't stand being fooled. ...

Obviously, buddy, the exclamation point is in the waiting state, that is, the short message that has not been sent yet, and there may be communication failure or IP dialing in front of the other party's mobile phone number. Take a closer look. In this case, just remove the IP part in front of the sending number! Have a plenty of yellow exclamation points! I wish you an early solution to the problem.
