What is the character limit for SMS?

The message encoding determines the character limit and the type of characters supported.

  • A single message with the default encoding can be up to 160 characters long.
  • When the length exceeds the single message character limit, the number of messages will be changed accordingly, based on the limits below:

 

16-bit

7-bit

Single SMS limit (x1)

70

160

Double SMS limit (x2)

128

306

Triple SMS limit (x3)

192

459

Quadruple SMS limit (x4)

256

612

Quintuple SMS limit (x10)

320

765

  • Devices show each SMS as one message, regardless of the number of characters. 
  • You can check the character and message number on the calculator in the top left corner.

If you want to send a long SMS (concatenated), you can send twice the content of a standard message. Unlike a single message, where all content is sent in one piece, a concatenated message is split into segments. However, the recipient’s device automatically combines these segments, displaying them as continuous messages.

Now you know what is the character limit for SMS.
