A. 1. Check Internet Connection: Ensure you have a stable Wi-Fi or cellular data connection. If using Wi-Fi, try switching to cellular data or vice versa to see if that resolves the issue. 2. Restart the App: Close Free Tone completely by swiping up from the bottom of the screen (or double-clicking the home button) and swiping the app off the screen. Reopen the app and try sending the message again.

B. 3. Check App Permissions: Go to Settings > Privacy > Contacts and ensure Free Tone has permission to access your contacts.
