I’ve been using my N95 8GB / Mobitel Broadband (3.5G HSPA) to connect to internet for a while now. But I was limited to Windows platform only. Today, I wanted to access internet using my linux partition too. This time google came to rescue.

This is how to do it…

Connect your phone via data cable, open terminal & type

lsusb

now you will get the following output

janapriya@ace-laptop:~$ lsusb
Bus 005 Device 001: ID 0000:0000
Bus 003 Device 002: ID 0421:0070 Nokia Mobile Phones
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 003: ID 0b97:7761 O2 Micro, Inc.
Bus 002 Device 004: ID 0b97:7762 O2 Micro, Inc. Oz776 SmartCard Reader
Bus 002 Device 001: ID 0000:0000
Bus 004 Device 002: ID 04b3:310b IBM Corp. Red Wheel Mouse
Bus 004 Device 001: ID 0000:0000
Bus 001 Device 003: ID 413c:a005 Dell Computer Corp.
Bus 001 Device 001: ID 0000:0000

Please note that above is for my laptop. Yours might be different.

Now note the line in which Nokia Mobile Phones is written. It has two number one is 0421 & other is 0070

we’ll take these numbers as 0×421 & 0×0070

0421 is the Vendor ID & 0070 is the Product ID

Now enter this comand.

sudo /sbin/modprobe usbserial vendor=0x(vid) product=0x(pid)

eg, in my case::: sudo /sbin/modprobe usbserial vendor=0×0421 product=0×0070

Now enter this command

wvdialconf create

You’ll get a long output which will be like

Scanning your serial ports for a modem.

Port Scan: S0 S1 S2 S3

ttyACM0: Max speed is 460800; that should be safe.
ttyACM0: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 — OK

Found an USB modem on /dev/ttyACM0.

Modem configuration written to create.

ttyACM0: Speed 460800; init “ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0?

Now.. notice the output says that there is a modem at /dev/ttyACM0 & max speed is 460800

now enter this command

sudo vi /etc/wvdial.conf

A file will open in vi editor. Now delete everything in that file & paste the following there

[Dialer Defaults]
Modem = /dev/ttyACM0

Baud = 460800

Init1 = ATZ

Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

ISDN = 0

Modem Type = Analog Mode

OK AT+CGDCONT=1,”IP”,”mobitel3g”

Phone = *99***1#

Username = “mobitel3g”

Password = “mobitel3g”

Stupid Mode = 1

save the file & you are done

Now whenever you need to connect, open terminal & type wvdial. Wait till some sort of IP adress is displayed like

pppd: ?[06][06][08]` [06][08]

primary DNS address 218.248.240.135

pppd: ?[06][06][08]` [06][08]

secondary DNS address 218.248.240.79

pppd: ?[06][06][08]` [06][08]

Now you are connected. Later hit ctrl+c to disconnect.
