Text too long error in SMS deliveries
We often find our SMS deliveries failing due to Text too long/SMS too long error even though the number of SMS per message is defined in the SMS Template.
The Maximum number of SMSes per message option allows you to define the number of SMS messages to send a message. If this number is exceeded, the message will not be sent. In such cases, it is always suggested to check the number of characters in the content inside the SMS.

Note: Even a difference of single character in the text can cause the number of SMS message to exceed.
