Cost per SMS

The cost per SMS message is based on a standard length message of up to 160 characters. Cosmic SMS supports messages up to a maximum length of 918 characters (6 x 153 characters). For long SMS messages, each 153 character segment equates to the cost of a standard 160 character message.

Note: Each part of a long message contains 153 readable characters. The remaining (nonvisible) 7 characters contain information that the receiving handset uses to reconstruct the message parts in the correct order and display as a single message.
