What is the maximum length of an SMS?
Articles in this section
The standard length of a text message is 160 characters. However, when you use special characters (i.e., Arabic, Greek, Russian), the number of characters per SMS decreases. Remember that if you want to send SMS in special characters, you need to use Unicode. In some countries, mandatory text or numbers take up extra characters, therefore the amount of characters that you can actually use is less. Check out the specific country restrictions.
If you need to send a longer SMS, you can activate the Enable message parts/Enable concatenated SMS setting when you create or edit an SMS integration.
