Hi Guys!

I have been successful in connecting my phone to internet on both Ubuntu and openSUSE using BOTH the methods. I am not sure about other distros however they should work.

There are two ways to connect to the internet using a GPRS modem phone. For the phones with BLUETOOTH :

THE BLUETOOTH CONNECTION METHOD:


You need to follow the steps below to connect to the internet using a bluetooth connection:

1: Switch on bluetooth on your phone and the computer. Make both your computer and phone visible to other devices.

2: Do a search from Linux for bluetooth devices near you. For this, you need to follow as:

Open terminal / shell / console (whatever you call it)
switch to root user using the command ' su'.
pass the command ' hcitool scan '

After sometime you will get the list of devices with their device address (also called as MAC address) and the device name. . . It will look something like:

12:12:12:12:12:12 PhoneName

Note down the device address of your phone (it will appear the place of the 12:12:12:12:12:12 , but in a similar format). You will need to use it later.

3: Now, you need to find which channel on your phone is assigned to what service on the phone. For this you will need to browse the device services. To do this, pass the following command:

sdptool browse 12:12:12:12:12:12

NOTE: Replace 12:12:12:12:12:12 with your phone address.

You will get something like this (I am showing the output I get for my phone):

4: We need to see which channel is assigned to the service "Dial Up networking". Do not be worried by the long output. It is easy to find it. In the above output (in the code box), search for the lines which say "Service Name" and fins the one which says "Dial Up networking". Then follow look through it till you come across another "Service Name". You can see that in the above output, the block below matches our requirements:
Quote:

Service Name: Dial-up Networking
Service RecHandle: 0x10002
Service Class ID List:
"Dialup Networking" (0x1103)
"Generic Networking" (0x1201)
Protocol Descriptor List:
"L2CAP" (0x0100)
"RFCOMM" (0x0003)
Channel: 2
Profile Descriptor List:
"Dialup Networking" (0x1103)
Version: 0x0100



In this entry, the channel number is given. We see that the channel is '2' (as shown by the line Channel : 2).

Note down the channel number. We will need in the next step.

5: Now you have all the required information for the work to be done. Now you need your computer to recognize the phone as the modem. for this, pass the following command:
Code:
00:0D:92:23:FC:25
rfcomm bind 0 12:12:12:12:12:12 2



Remember to replace the address 12:12:12:12:12:12 with your device address and the number '2' at the end with the channel number you will get for YOUR phone.






That was the Bluetooth way. However , if your device is detcted by Linux via Data cable as a modem, things are much easier. You will, in this case have to follow the following steps: Quote:

1: Connect the data cable to the phone.

2: Some phones as for selection of modes e.g. nokia phones ask to select either the data mode or PC suite mode and Sony Phones ask to select either the 'file transfer' mode or 'phone mode'. Select the one which you use on Windows to connect to internet (on nokia it is PC suite mode or Nokia mode and on Sony phones it is 'phone mode'). Wait for 2-3 seconds to get the device detected by Linux.

3: launch the terminal and switch to root by passing the command: su . Enter the password and you will get the # prompt.

4: go to the /dev directory by passing the command: cd /dev

5: Check for the ttyACM devices. issue the command : ls ttyACM*. It should show either ttyACM0 or ttyACM1 as output.

NOTE: If it does not show any output, then your phone is not detected !

6: Note the output which is mostly either ttyACM0 or ttyACM1.




So till now, you have made Linux recognize the phone as a modem either via Bluetooth or via Data cable OR BOTH WAYS. Now you need to dial to connect to the internet. For this you will have to copy the following as save it as /etc/wvdial.conf using the root account:
Code:

[Modem0]
Modem = /dev/rfcomm0
Baud = 230400
SetVolume = 0
DialCommand = ATDT
FlowControl = Hardware(CRTSCTS)

[Modem1]
Modem = /dev/ttyACM0
Baud = 230400
SetVolume = 0
DialCommand = ATDT
FlowControl = Hardware(CRTSCTS)

[Dialer GPRS]
Username = 1
Password = 1
Phone = *99***1#
Mode = 1
Inherits = Modem0

[Dialer DATA]
Username = <>
Password = <>
Phone = *99***1#
Mode = 1
Inherits = Modem1

[Dialer Defaults]
Modem = /dev/rfcomm0
Baud = 230400
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","airtelgprs.com"
ISDN = 0
Modem Type = Analog Modem
Area Code =
Phone = *99***1#
Username = <>
Password = <>
Ask Password = 0
Dial Command = ATDT
Stupid Mode = 1
Compuserve = 0
Force Address =
Idle Seconds = 3600
DialMessage1 =
DialMessage2 =
ISDN = 0
Auto DNS = 1




Now when dialing via Bluetooth, you will have to pass the following command:
Code:
sudo wvdial GPRS



It will ask for the root password. Enter it and it should connect.

For dialing via data cable, you will have to pass the command:
Code:
sudo wvdial DATA



This will also ask for the root password. Enter the password and it should proceed.

If you have a problem with that, you can reply back with the problem.

My friend was successful in connecting her Macbook to the GPRS on her cellphone I was impressed since she was computer-illiterate to a certain point.

Wow thanks for this, i'm using Ubuntu, no problems here

First of all welcome to Astahost. And it really feels great if I am giving something to the commuity....

wvdial wont work
Internet Connection In Linux Through Mobile

Hi
Everything works until I have to fix with my wvdial.
I first copied yours and tried and I only get Cannot open /dev/rfcomm0: Host is down

I googled a bit for the wvdial but it did not work either.

Thanks for the great howto btw
