How long messages can I send?
An SMS can normally include 160 characters. If a longer message is sent to SMS Submit it will be split into multiple SMS which will be re-assembled into a long message by the phone/terminal. This is called "concatenated SMS".
Actually a SMS is up to 1.120 bits which corresponds to 160 7-bit characters, 140 8-bit characters (binary SMS) or 70 UCS-2 characters (Unicode). So, the number of parts needed for the message depends on the type of message content.
Please note that each SMS is charged meaning that one long message will cost more than one SMS.
