How can I use the call forwarding service and have it appear on my caller’s and receiver’s screens?

You can activate this service by entering the call settings, then selecting call forwarding and choosing the forwarding status you desire. After that, a forwarding indicator will appear on your phone screen. When someone calls you, the caller will hear the voice message “The call will be forwarded at the subscriber's request.” There is no indication for the caller that you have used this feature. When you choose forwarding, the caller will only be informed after hearing the voice message that the call has been forwarded based on your request.
