The "... in the range 0 through 255" comes from the specs. as is.

As far as I understand, 0xff is also a valid value, but I don't think a 
subscriber can reach such value. Even in case of the multi-part SMS, when each 
part has a unique Message Reference. The current code does limit the amount of 
parts to 255.

How often do you send SMS messages consisting of 256 parts? ;)
In case of OTA messages, I don't think a regular SIM has such amount of RAM 
available.
