If you are using Maestro (Lite) 100 GPRS/GSM modem, can be a little bit difficult to do dial up using that device. Means we’re using the modem for dial up GPRS to connect to internet. It’s very rare modem, for really special purpose modem. A little bit hard to find the configuration on the internet. After doing some work around to find out, trying and searching the best way to connect with it. Finally I am able to connect.

Configuration:
OS: Ubuntu (Gutsy Gibbon)
Modem: Maestro Lite 100 GPRS/GSM Modem
Connection: /dev/ttyUSB0

Here’s the configuration in /etc/wvdial.conf, I’m using AXIS simcard (you can edit you own username, password and access point):

[Dialer Defaults]
Username = axis
Password = 123456
Phone = *99***1#
Init2 = AT&F
Init3 = AT+CGDCONT=1,”IP”,”axis“,”0.0.0.0″,0,0
Stupid Mode = 1
Inherits = Modem1
New PPPD = yes
Dial Command = ATDT
ISDN = 0
Modem Type = USB Modem

[Modem1]
Modem = /dev/ttyUSB0
Baud = 9600
SetVolume = 0
Dial Command = ATDT
Init1 = ATZ
FlowControl = crtscts


After successfully dial up, you will be able to browse the web. Here’s some log when connect:

If you are using Huawei E220 HSDPA Modem (Some time I use this one also), you can find “how to” here.
