Use dmesg to see what ports are provided for this device. If there is more than one, try to use other than ttyUSB0.

See also this topic: SMS and data connection, if it gives any glue.

Use /dev/ttyUSB1 as it works.

The sending fails probably because of the missing information of SMSC (Service Center). Usually this is stored in SIM, but not in all cases. If you do not know what is the correct number of SMSC for that operator, put the SIM into your handset, and check the setting with it. The number might be something like 584240000954, but check it before trying.

The modem setting in the smsd.conf is:
smsc = number of SMSC in international format without the + sign

You also have some unexpected input in the log. First try with a modem setting:
init = AT^CURC=0

If unexpected input still continues, add a setting:
init2 = AT^BOOT=0,0

Also, as this device does not support Bit Error Rate, add a setting:
signal_quality_ber_ignore = yes

CheckSuccess=5

modify /etc/udev/rules.d/

write:
SUBSYSTEM=="block",
ACTION=="add",
SYSFS{idVendor}=="12d1",
SYSFS{idProduct}=="1446",

The usb_modeswitch has nothing to do with your problem. Please do not waste your time with it, as the /dev/ttyUSB1 already works properly.

In the post #8 there was suggestions what to to. Did you read that post, and checked SMSC?

What do you mean with this? In Windows you tried to send SMS using some program and the same SIM, and the sending was successful, right? Please answer, it is important to know if the SIM works. What was that program, and was there SMSC set in the settings of that program?

If you do not want to check what is the correct number of SMSC ( as mentioned in post #8 ), I cannot help you with sending problems. In any case, as you can see from the log, receiving of SMS and anything else than sending works, meaning that there is no problem with Ubuntu, with USB or with udev.

My ultimate option:

AT COMMAND with minicom:

AT
AT+CMGF=1
AT+CSCA="+584240000954"
AT+CMGW="584269984651"
> A simple demo of SMS text messaging. (When finished, press Ctrl+z of the keyboard.)
AT+CMSS=1 (the number is from returned value of CMGW)



Result:

AT+CMGF=1
OK

AT+CSCA="+584240000954"
OK

AT+CMGW="584269984651"
> A simple demo of SMS text messaging. (When finished, press Ctrl+z of the keyboard.)
>

and logic..... not send SMS......

Did you check what is the correct number of SMSC using your handset? I see that you have tried to use that number which I mentioned, but as I said, it is not sure if it's a correct number. With your handset you can easily check what is the correct number, and it does not take 24 hours... :P

In many cases, CMS 500 with Huawei is caused by the incorrect or missing number of SMSC. It is very important that you check the case now, it not already done with care.

Also, when the SIM (from modem) is in your handset, try to send SMS with it. This is important. You should be able to send SMS, otherwise the SIM is broken, or not activated, or pre-paid with zero balance.

You have a handset, right? And it has a different SIM than what is in your modem? If this is the case, you could check what is the number of SMSC of the SIM which usually is in the handset, and then put that SIM to your modem, and set smsc, and try sending.
