Message Concatenation
Many markets allow you to concatenate messages, or to deliver multiple messages together as one long message. During message creation in MobileConnect, select Concatenate Message to concatenate your outbound message.
If you concatenate your message, your maximum character count per message is reduced by seven characters. Messages longer than 160 characters are reduced to 153 characters. Messages longer than 70 characters containing any non-GSM characters are reduced to 67 characters. The reduction happens because concatenating a message adds a header to the metadata in an SMS message. This header provides the message delivery order to the carrier. While this header doesn't show on a mobile device, it uses a small amount of data that would otherwise be used for more characters.
You are charged for the number of sends that would have occurred if the message wasn’t concatenated.
For inbound messages, MobileConnect records only the first 153 characters of messages longer than 160 characters. If an inbound message contains any non-GSM characters and is longer than 70 characters, MobileConnect records only the first 67 characters of the message.
Without concatenation, this outbound message is deployed as two messages because it exceeds the maximum character count:
