How SMSC works

To be able to send a message to a destination number, this process is not as easy as sending and receiving messages. The reason for this is that Telkomsel’s SMSC has just been replaced and, of course, sends the signal to HLR first using the STP signal of the message you want to send.

The HLR responds to the signal by checking whether the destination number is active and indicates where the number is. If the destination number is active, the message is sent immediately. However, if the number is not active, the Short Message Service Center will keep the message.

When a destination number is activated, the HLR sends a signal to the SMSC to provide the status of the location. The Short Message Service Center will then send you the message in a point-to-point format.

When the message is sent, you will see a notification that “the message has been sent” and SMSC will not send the message again.  If the Short Message Service Center is busy, it takes a long time for the messages you send to reach their destination number.

This is certainly for the convenience of the provider user. Not only when sending SMS, but also when sending messages using other applications that require the use of a phone number.  So the description of SMSC that Telkomsel has just changed is really something you have to understand.
