The standard text message contains up to 160 characters (letters, numbers, simbols), but the new generation of SMS allows the sending of messages that are longer than 160 characters.
The mobile handsets of new generations, support two ways of coding an SMS, that influences the charging:
- 7 bit GSM Alphabet code (ASCII) that does not support letters č, ć, đ, š and ž and can contain the maximum of 160 characters
- 16 bit Unicode2 code, that allows the usage of letters č, ć, đ, š and ž and can contain up to 70 signs. The usage of mentioned signs (latin and cyrillic alphabet) the longer message or the message that contains more than 70 signs is charged as a series of „short“ SMS.
Depending on the model of the mobile handset, if the recipient of the SMS uses the prone that does not support longer messages, he will receive only one message, or the series of short messages will be delivered.
The messages that contain more than 160 standard characters (or 70 non special characters) will be charged and in the specification of the traffic will be shown as separate „short“ SMS.
