According to the 3GPP standard, the maximum individual short message size is 1120bits. When using different coding scheme, the maximum individual short message size could be different. Please see details as below:

  1. Using GSM 7-bit alphabet, the maximum individual short message size can reach to 160 characters (1120bits/7 bit=160).

  2. Using GSM 8-bit alphabet, the maximum individual short message size can reach to 140 characters (1120bits/8 bit=140).

  3. Using UCS2 16-bit alphabet, the maximum individual short message size can reach to 70 characters (1120bits/16 bit=70).
