Sending SMS AT-commands

I have USB-Modem Huawei E171 with working SIM-card.

I'm trying to send SMS-message using Putty and have 500 error:

AT

OK

AT+CMGF=1

OK

AT+CMGS="+7923*******",145<enter>
>Hello<ctrl-z>

+CMS Error: 500

What can I do? I know that error 500 is unknown error. So I thought that somebody can have ideas about this thing. I checked the program, which called Huawei Modem, and it successfully sent my SMS. Feels like I didn't do something to initialize the modem.
