I can receive text messages, but I can't send text messages. Do anyone understand the symptoms of this error? It started 3 days ago. Do anyone have a solid solution to rectify this problem?
What MrGhoul said, but also, make sure your APN settings are correct and updated. Some carriers fail to automatically update the APN settings and you must do it manually (StraightTalk is bad about this). Also, go into your messages settings and make sure RCS chats are working properly. Turn it off for a bit then back on, and see if that also fixes it.
