The first that you need to do is to reboot the phone and see if that fixes the problems. After you reboot the phone you need to test if the text messages are sent with at least two other people, so that you will make sure that it isn't the other person's phone the culprit.

Enable and Disable Airplane Mode:

You can put the phone in Airplane mode and then disable it, as it might be buggy and this should fix it. Reboot the phone after you enable Airplane Mode, and disable it after the boot is done. If this fixes the problem, then you are lucky as no files need deletion.

Delete Old Text Message Conversations:

Please note that the Messaging app can reach a full capacity, and you might not be allowed to send anymore messages. So, make sure to delete all the old texts before trying to send out new ones.

Clear Messaging app Cache and Data:

For this method you need to open the Settings menu, go to Apps, tap the 3-dot icon and enable "show system apps" option. Now scroll through the Apps list and find Messages.

Open the Messages menu from the Apps list, go to Storage and clear its cache. Confirm action, then retry to send a new text and see if that fixes it.

If you still can't send new text messages, then you should try and clear the Messages app data: go to the same Settings> Apps menu, enable "shows system apps" and find Messages. Go to Storage and use the Messages app "clear data" option. Confirm process and you are done.
