How do I send long/multiple (concatenated) messages in one SMS?

Enabling message parts allows you to send messages that are longer than the maximum number of characters normally allowed per SMS. Messages are split into smaller parts and recombined at the receiving end to appear as one SMS to the recipient.

Note that you will be charged for each message part.

When you set up a new SMS integration from the user portal, use the toggle under 'SMS Channel Settings' on the API setup details page to enable message parts (disabled by default). Then set the maximum number of message parts allowed.

You can enable/disable message parts and edit the number of message parts allowed by navigating to My Workspace --> SMS and selecting the integration from the table.


If you are currently using the old user portal:

You can set the maximum number of message parts allowed during your integration set-up (from your dashboard), under Settings. The default setting will accept messages that are no larger than three message parts but you can increase this value according to your needs.

If you have questions about switching to the new portal, see here or contact our support team.
