* First enter this command

Modem = /dev/ttyUSB0

Baud = 115200

Set Volume = 0

Dial Command = ATDT

Init1 = ATZ

Flow control = Hardware (CRTSCTS)

[Dialer Command]

Stupid mode = 1

Inherit = Modem0

  • After this your system is ready for connection.

some modern USB modems work automatically without installation and/ or configuration. however for some old fashioned USB modem you can use wvdial to connect. wvdial use /etc/wvdial.conf as configuration file. most ubuntu derivatives have wvdial pre-installed. however the configuration depends on your telecommunication carrier. /etc/wvdial.conf that matches  my carrier in Indonesia looks like this

[Dialer Defaults]

Init1 = ATZ

Init2 = ATQ0 V1 E1 S0=0 &C1 &D2

Init3 = AT+CGDCONT=1, "IP", "telkomsel"

stupid mode = yes

Modem Type = USB Modem

ISDN = 0

New PPPD = yes

Phone = *99**1*1#

Modem = /dev/ttyACM0

Username = wap

Password = wap123

Baud = 460800
