IMPORTANT

Ensure that the total number of characters for the resulting SMS is no more than 160.

If it is more than 160 characters, the SMS will be sent in multiple parts and you will be charged for each part.

Be aware that the Vendor or Site Reply Name, defined in the SMS Vendor Settings,  will be added to the resulting SMS by default and therefore takes up available characters.

See How is an SMS Message created for more information.
