SMS

This is the screen used to compose and send an SMS message. For background, see Concepts|SMS.

The fields are as follows:
Phone - the phone number to which the SMS will be sent. If the supplier has multiple phone contact numbers that are SMS enabled, then there will be a pull-down list for you to select from.
Message - the text of the SMS message - a maximum of 160 characters. The counter on the top of the box (96 in the above sample) shows how many more characters you can enter before your text will be truncated.

Press the OK button to send the SMS.
