SMS Not Sending: Quick Troubleshooting

If your SMS messages are not being sent, follow these steps:

1. Do you see an error in the status column?

• If yes, what does the error say?

  • If it says "Access denied": Your firewall or antivirus is blocking QuickText. Please turn off your antivirus/firewall or add an exception for QuickText, then try again.

  • If it’s a different error: Copy the error and email it to me at [email protected].

2. Are the messages marked as transmitted, but not visible in your SMS app?

• This usually means the connection to your phone was lost.

• Make sure the KDE Connect app stays open on your phone while you send messages. Don’t close or swipe away the app during sending.

3. Do you see the messages in your SMS app, but the recipient doesn’t get them?

• Your phone provider may have blocked your number for bulk sending.

• More info and what you can do: SMS is marked as sent on my phone, but the recipient does not receive it
