Hello everyone! Sorry for wrong output. When I tested that time, I dialed using command "wvdial /etc/wvdial.conf" instead of "wvdial". Now I have read "man wvdial" one more time and I understand my stupid mistake. Version of slmodemd is: ezhik@ubuntu-laptop:~$ sudo slmodemd --version SmartLink Soft Modem: version 2.9.11 Jun 23 2010 23:15:35 I have compiled it myself from source slmodem-2.9.11-20100303.tar.gz. I use unloading script before I initialize the modem: ezhik@ubuntu-laptop:~$ sudo ./unloading /* I've skipped output*/ ezhik@ubuntu-laptop:~$ sudo slmodemd -c NEW_ZEALAND --alsa hw:0,6 SmartLink Soft Modem: version 2.9.11 Jun 23 2010 23:15:35 symbolic link `/dev/ttySL0' -> `/dev/pts/2' created. modem `hw:0,6' created. TTY is `/dev/pts/2' Use `/dev/ttySL0' as modem device, Ctrl+C for termination. But still the problem is the same - No Carrier. I used my phone to hear how the modem dials. It starts to dial correctly with all that noises and sounds, but aborts in few seconds. ezhik@ubuntu-laptop:~$ sudo wvdial --> WvDial: Internet dialer version 1.60 --> Cannot get information for serial port. --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 S0=0 X3 &C1 &D2 +MS=34 ATQ0 V1 E1 S0=0 X3 &C1 &D2 +MS=34 OK --> Modem initialized. --> Sending: ATDT087305656 --> Waiting for carrier.
