Huawei ME909s-120 & SMS sending

Is it possible to send SMS without “Ignore DirectIP Modem” option enabled from /port/firmware?

I am successfully able to send SMS when this setting is enabled using:

/tool sms send usb2 "phone_number_here" channel=4 message="Hello!"

However, as soon as I disable the “Ignore DirectIP Modem” setting and then reboot, the usb2 port becomes inactive (and after second restart disappears completely).

I have RB953GS-5HnT with 6.37 (stable).

PS.
If SMS sending not possible, would there be any way just to know what is the phone number of that SIM card? I see all the information about IMEI, IMSI, Current Operatior, Current Cell ID etc, but no where can I find the phone number.
