grab minicom, connect to ttyUSB2 and then run the following:
AT+CMGF=1
AT+CNMI=2,2,0,0,0
then send yourself a message while your still attached to the port. you should see it come across plaintext.
Now if that works you can do the following 
sudo over to root:
apt-get update
apt-get install smstools
edit /etc/default/smstools
change USER to root
delete /etc/smsd.conf
create a new /etc/smsd.conf with the following

reboot.
if you dont have modemmanager disabled, youll need to kill it or this wont work
killall /usr/sbin/ModemManager
now when you get an sms, it should pop up in a little window on the desktop. you can change this to do whatever you want but I like it popping up.
to send you can just run sendsms 19992223333 “this is a text”
