What is the maximum length of an SMS?

When using long messages, there are 7 characters per SMS that are used to connect the SMS technically to each other.


• 1 SMS : 160 characters
• Long message of 2 SMS : 306 characters (2 x 153 characters)
• Long message of 3 SMS : 459 characters (3 x 153 characters)
• Long message of 4 SMS : 612 characters (4 x 153 characters)
• Long message of 5 SMS : 765 characters (5 x 153 characters)

Once you exceed the 160 character limit, messages are split in 153 character parts, up to 10. This means you can have a message of up to 1530 characters. That message will cost you the price of 10 short messages.
Please be aware that some characters (see "Set Extension" here below on the right) will count for 2 characters.

IMPORTANT: Unicode messages contain a maximum of 70 characters per part, also with 7 characters needed to connect multiple SMS.

• 1 SMS : 70 characters
• Long message of 2 SMS : 126 characters (2 x 63 characters)
• Long message of 3 SMS : 189 characters (3 x 63 characters)
• Long message of 4 SMS : 252 characters (4 x 63 characters)
• Long message of 5 SMS : 315 characters (5 x 63 characters)
