Last month, my home internet connection got disconnected a couple of times. However, I’m glad and lucky that I have a cell phone that I can use as a modem for my Linux box every time my internet provider messes up.I’m going to share to all of you how I use my Nokia 9500Communicator mobile phone as Modem.
Note: this may also work with other Nokia cellular phone models that have internet capability.
2. Open a terminal and type:
lsusb
3. You will get an output almost similar to this one:
Bus 003 Device 004: ID 0421:0405 Nokia Mobile Phones 9500 GSM Communicator
Bus 003 Device 002: ID 05e3:0606 Genesys Logic, Inc.
Bus 003 Device 001: ID 0000:0000
Bus 001 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 001 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
5. Enter this command:
sudo /sbin/modprobe usbserial vendor=0x(VID) product=0x(PID)
eg, in my case: sudo /sbin/modprobe usbserial vendor=0x421 product=0x405
6. Now enter this command:
wvdialconf create
7. You will get an output which will be similar to this:
Editing `create’.

ttyACM0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 — OK
Found an USB modem on /dev/ttyACM0.
Modem configuration written to create.
ttyACM0
8. Find the location of the modem, in my case at /dev/ttyACM0, and also the Max speed which is 460800.
9. Now enter this command:
sudo vi /etc/wvdial.conf
10. A file will open. Delete everything in that file and replace it with the following: (Don’t forget to put the ‘modem location’ and ‘max speed’)
[Dialer Defaults]
Modem = PUT MODEM LOCATION HERE
Baud = PUT MAX SPEED HERE
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem
Phone = *99#
Username = username
Password = password
Stupid Mode = 1
11. Save the file, and the setup is done.
12. You can connect by opening a terminal and then typing the command: wvdial. You will then get an output like shown below if everything worked as expected.
