Unable to send SMS on US Mobile GSM (T-Mobile MVNO)
I have just briefly had a look through the code.
What appears to happen is that chatty has no SMS protocol enabled at that time making the "+" button greyed out.
Presumably chatty does not "find" the modem on startup and therefore has no SMS support.

Could you try doing the following:
After boot wait a little bit to make sure the modem is online and connected to your carrier (I don't think you necessarily need to be connected - I could be wrong though).
then run "killall chatty" a few times until you get "no process found" and then start chatty again from the UI.

I have the suspicion that the "protocol detection" is only run once on startup and maybe it is during a time (since a daemon is autostarted)
where the modem is not yet "fully up". Obviously when you receive a new SMS chatty will then know that SMS work (if that makes sense) ;)
