Is there a limit on the number of characters used in an SMS?

Yes there is a limit of 5 SMS messages (765 characters) for our Marketing and Transactional SMS.

An SMS message can have up to 160 characters including 'space' and 'enter'.

For SMS messages above 160 characters, the length of 1 SMS message changes to 153 characters. For example, if your message has 320 characters, your campaign will be sent as 3 SMS messages (153+153+14 characters).
