How many characters are allowable in one SMS?
You have the capability of sending messages in excess of 160 characters through our services.
When sending a message in excess of 160 characters, the message is broken up in to message parts of 153 characters, and sent to the handset. The handset then reassembles the message, displaying the message as one extended-length, concatenated message. When sending an extended-length message you are charged for each 153 character part that is sent. This charging process is dictated by the network operators.
You can send the maximum message length of 918 characters, or send a message length of 402 characters for the Unicode character set.
