SMS lengths

Nombre de caractères par SMS

Unicode is an international standard that allows any character in the world to be represented, including complex characters and emojis — that is, more than 65,000 different characters (see the Unicode character list).

Unicode SMS messages use 16 bits to encode each character, which allows them to support a much wider variety of characters compared to traditional 7-bit SMS. However, this wider variety limits the maximum number of characters per SMS to 70, then 67 characters from the second SMS onward.

Concatenated Unicode SMS messages can contain a maximum of 670 characters, i.e. 10 SMS messages.
