How to send SMS via 3G Modem - ZTE MF190

I have a modem ZTE model MF190 and would like send SMS through AT commands on the serial port. My problem is: when I send AT commands, the modem responds with an error +CMS ERROR: 305

Researched a lot about the error, and he is due some invalid character in the message, but am not writing anything wrong in the message.

check:

commands sent

The funny thing is that if I send an empty message, I get the SMS (obviously empty)

Someone has been there and knows how to configure or send SMS by this model of modem?

Try hitting Ctrl+Z instead of Enter.

EDIT 2016-04-05: Note for anyone doing this using socat or similar under *nix: you will need to hit Ctrl+V prior to hitting Ctrl+Z or it will suspend socat to the background instead of sending the control character to the port.

The error seems to signify that one or more parameter values assigned to the AT command are invalid for a text mode initiated SMS.

What is the command string being sent?
