The length of a standard SMS is 160 characters. WinSMS supports long SMS messages of up to 918 characters. This is equivalent to 6 message parts in total.
The messages are broken up as follows: The first part will be 160 characters. The second part will be 146 characters and the remaining four parts will be 153 characters each.
Messages are concatenated in accordance with the Global System for Mobile Communications and their protocols for cellular networks using mobile devices. (This just means that it is an industry-standard your cellular network has to follow.)
