How many characters can I send in an SMS?
Posted by Nick James on 13 May 2021 04:18 PM
A message can be classified as 2 types:
A standard SMS message has a maximum of 160 characters. Longer messages are definitely possible, however please be aware that exceeding 160 characters will constitute a ‘second’ message. The end user will see this as 1 long message on their handset.
When a message is longer than 160 characters, this is referred to as a multi-part message as it contains multiple messages (or multiple-parts). The total SMS limit then becomes 153 characters per ‘part’ as the 7 characters are used up by invisible headers and footers which denote which part of the message is being sent (i.e. Part 1 of 2). For example: If a message is longer than 6 message parts, it will be truncated (see below):
Standard English Characters:
Non-GSM (Unicode) characters:

Note: Line breaks/carriage returns count as 2 characters.
Can I send Emoji?
Yes you can, provided that the recipient network supports it. If the recipient network doesn't support them, they will be stripped out. Emojis are counted as 2 unicode characters each (please note that using Emoji changes the encoding of the message to Unicode).
The library of Unicode Characters typically increases periodically as new characters are added. While we do automatically convert some common Unicode characters in the New Message page, we will display an alert when new Unicode characters are detected. We can also turn on our 'Smart Encoding' feature for your account to automatically convert some common Unicode characters as you send messages. Please contact our friendly support team if you have more questions or wish to turn on 'Smart Encoding'.
