"Message not sent" error
If you are getting a persistent "Message not sent" error message or notification when using 8sms, you may have an old undelivered sms stored in your phone.
Unfortunately, 8sms may not be able to show the undelivered sms to you.
One possible solution is to use the Handcent SMS application which has a feature to show the "undelivered messages" folder.
- Download and install Handcent SMS.
- If you are using Android 4.4.x KitKat, set Handcent SMS to be the default sms app.
- View the "undelivered messages" folder in Handcent SMS and delete any old,undelivered sms messages.
- If you are using Android 4.4.x KitKat, set 8sms to be the default sms app.
- Uninstall Handcent SMS.
