@menon92 set your PORT to dev/ttyUSB2.
The TimeoutException is expected in this case. You can't catch incoming calls, USSDs and SMS messages with dev/ttyUSB0 port on Huawei modems, because this channel doesn't contain modem notifications.
I tested ussd_demo.py with my Huawei modem and it's working as expected:
dev/ttyUSB2 => USSD working fine ✓
dev/ttyUSB0 => TimeoutException ✓
If your code still doesn't work, uncomment logging.basicConfig(... line and post here your console output.

serial.serialutil.SerialException: Attempting to use a port that is not open
It seems your modem unexpectedly restarts itself? (Maybe a bug in the modem firmware?)
It fails at simple CLAC command, the response is cut after ~300 characters.
Could you start gsmterm from tools/ folder?
python gsmterm.py -r /dev/ttyUSB2
type AT+CLAC, Enter
is the command working properly?
(Press CTRL+] to exit.)

Done.
I think AT+CLAC command sometimes works and sometimes not working.
If there is problem with modem firmware or modem unexpectedly restarts In that case what can i do ? should i try a new modem with the same code ? or anything else i can do .
Thanks @babca

This seems to be related to the modem not to python-gsmmodem library.
Please try it again and type ATZ command before AT+CLAC command.
Both should output OK on the last line, every time.
I don't think it will help, but you can also try to lower baudrate:
python gsmterm.py -r /dev/ttyUSB2 -b 9600
Which modem do you use?
Try a different modem if you can. Huawei E372 and E160 are working fine with ussd_demo.py.
