Long messages (multi messages greater than 160 characters) not being sent.

[rknell]

Hey I'm going to investigate it and hopefully come up with a solution, but when I try to send a message greater than 160 characters - one that would traditionally roll over to a new message but is invisible to us these days - it doesn't send but comes back with a success response.

Not sure what needs to be done to chain messages together but wanted to open the issue here so I can track any progress I make (if any!) or at least make it a known issue.

Found this wikipedia article that seems to outline the implementation required:

I have submitted a PR that is working for me to resolve this isssue:
