Why can't I receive the missed message of callback treasure after setting call forwarding?

Callback service is based on call forwarding technology. If you set up call forwarding yourself during the service, the service will be temporarily unavailable, and you need to call the user to the service platform again before you can continue to use the service. You can set the unreachable phone to1301034101,or you can dial * 62 *13010341# directly on your mobile phone.
