What is the recommended maximum number of parts when sending concatenated messages?

The recommended maximum number of parts of a concatenated message is six. Sinch does not recommend sending messages with more than six parts as there might be a limitation at the respective service providers or on the handset where the messages are being terminated.

Please, take a look at the What is a Concatenated SMS? article,  to learn more about concatenated messages and at the Special Character Considerations for SMS Messaging article, to see how special characters can affect the length of your messages.
