How to Set Your Mobile Phone as a Modem

Mobile phone is included in the wireless technology. Talking about the wireless technology, It reminded me with my old amateur radio. First amateur radio needs an antenna to send and receive the information. For example, My amateur radio use a simplest antenna. People call it Open dipole antenna. It is made from the long measured wire, and a winding wire.
If you ever use the radio, you will hear the noise beside the vocal. That is my first wireless experience.
Now, Internet. Internet is included in 7 wonders of the world (Based on USA Today). Internet is a new media and it makes the world become smaller than before. Every one know about internet. Internet can be accessed by mobile phone, TV Cable network, coaxial, satellite, etc. Now, I'll tell you about connect your computer to the internet by mobile phone.
Before we begin our adjustment, make sure that you have activated your cellular GPRS (General Packet Radio Service) from your provider.
OK, I think you have activated your cellular GPRS. But, here I'm using UNE (Ubuntu Netbook Edition). I think this tutorial can run on plain Ubuntu or it also can run on the modified Ubuntu. Let's do it!

1. First, plug your mobile phone.


2. Then, make sure that you have installed wvdial packets. If you never yet install it, you shall install it.
   There are two ways to install wvdial packets. First, via command line (console). Open your console, then type this:

   sudo apt-get install wvdial

   
   Second, you can also download the packets. Click here to download the packets.
   P.S. whenever you will install any programs on Linux via console, you must be connected to the internet web.


3. After you install it, open your console then type this:

   wvdialconf

   so, on your console will appear this:

   Editing `/etc/wvdial.conf’.
   Scanning your serial ports for a modem.
   ttyS0<*1>: ATQ0 V1 E1 — failed with 2400 baud, next try: 9600 baud
   ttyS0<*1>: ATQ0 V1 E1 — failed with 9600 baud, next try: 115200 baud
   ttyS0<*1>: ATQ0 V1 E1 — and failed too at 115200, giving up.
   Modem Port Scan<*1>: S1 S2 S3
   
   Sorry, no modem was detected! Is it in use by another program?
   Did you configure it properly with setserial?

   It means that there is no modem detected. But, don't worry. It will run properly.


4. login as a super user:

   sudo -s

   enter your password, and you have been logging in.


5. Next, type

   lsusb

   then, on your console will appear

   root@ubuntu:~# lsusb
   Bus 002 Device 003: ID 0bda:8198 Realtek Semiconductor Corp.
   Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
   Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
   Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
   Bus 005 Device 005: ID 05c6:9004 Qualcomm, Inc.
   Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

   Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
   Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

   Those are informations. It will inform us about any hardware that have plugged on USB ports.


6. then type

   modprobe -r usbserial

   after that, type this:

   modprobe usbserial vendor=0x05c6 product=0x9004

   Maybe, you will be confused, where we will find those number. OK, read the informations above, and you will get it. Here, I use the mobile phone that it use Qualcomm, Inc. chip.


7. After that, type

   wvdial

   then will appear:

   
   --> WvDial: Internet dialer version 1.60
   --> Cannot get information for serial port.
   --> Initializing modem.

   you have connected to the internet.
