I was testing the plugin today and realized that on my Sprint phone you can only receive about 160 Characters (including spaces) at a time. I sent about 300 Characters to test and see if it would send two texts to complete the message and it did not.
This might just be sprint related but I do not know that for sure. Does anyone know if the character count includes the subject?
If most phones are limited to say 160 Characters it would be a good idea to make the message box have a character count associated with it. That way the admin can control their content more and make sure their users are getting all of the data sent. Another option would be to somehow tell the script to only send x amount of characters at a time. For instance IF x > 160 (send first 160 characters), Then send the rest in another operation if not > than 160. You get the idea.
