SMS message content and SMS symbols

---

Quantity of symbols

The character limit for a single SMS message is 160 characters. Each message sent by multiple SMS messages is limited to 153 characters, rather than 160 due to the need for user-data headers information. Mobile phones use the information to enable them to link long messages.

If you include even a single character (for example CYRILLIC, BALTIC alphabets) that is not supported in the default alphabet, all message characters will be encoded in a different standard which will cause a maximum number of characters to drop to only 70 per message. If the message is longer than 70 characters it will be divided into two parts, where the second message will also be limited to 67 characters, even if the second message contains only the basic alphabet. The same rules are applied to every consequent message part.

Recommendation: use simple LATIN characters.

Quantity of messages

Any text with more than 160 symbols in it will bi split into several messages and each of them is paid separately by the sender. System will automatically calculate how many messages are necessary in order to send your text («Count SMS» field).

Variables

On the right from the text field you will be able to indicate necessary variables which will automatically be inserted into your message and will vary according to the individual meaning of each contact. For example, when using variable Name {NAME} the system will automatically insert the corresponding recipient’s name into each message.
