Long SMS Sending Process

You can send a long SMS using one of the following options:

  • MESSAGE_SEGMENTATION: Breaks the SMS into multiple parts (segmentation).

  • MESSAGE_PAYLOAD: Sends all the data in one SMS.

Note:

When you use MESSAGE_SEGMENTATION, the system by default breaks lengthy outbound SMS messages into segments no larger than:

  • 160 characters: If the SMS Character Encoding is set to a 7 or 8 bit character encoding.

  • 70 characters: If the SMS Character Encoding is set to one of the 16 bit encodings.

This default setting can be changed by adding the following properties in $MMSSERVER_HOME/lib/config/smsserver.properties and then running the service mmsserver restart command:

  • smpp.max.segment.size=160

  • smpp.max.segment.size.16bit=70

When outbound SMS messages are sent, they are broken into segments of the specified size. The maximum segment size should be obtained from the SMSC.
