Internet on Sony Ericsson Mobile using Broadband

Sony Ericsson Users can now access all mobile internet services free of cost using your Broadband connection.

My model Sony Ericsson w700i must use TCP/IP for its data connection. I thought, why not make a TCP/IP connection to my local area LAN and surf the Internet through my broadband? The first thing i can do is to ask google. I have come across the Sony Ericsson SDK which offers me such features. I have finally found out how to make it.

Required Stuff:

1. Sony Ericsson Compatible Model (That support GPRS, USB/Bluetooth Connectivity, MIDP 2.0, CLDC 1.0+)

MIDP 1.0 and CLDC 1.04:

P800 series, T610 series, T630 series, Z600 series

MIDP 2.0 and CLDC 1.0 HI:

P900/P910 series

MIDP 2.0 and CLDC 1.1:

S700/S710 series, V800, F500i, J300 series, K300 series, K310 series, K500 series, K510 series, K600 series, K610 series (Java Platform 7) , K700 series, K790 series (Java Platform 7) , K750 series, K800 series (Java Platform 7) , P900, P910, P990

M600, W300 series, W550 series, W600 series, W700 series, W710 series (Java Platform 7) , W800 series, W810 series, W850 series (Java Platform 7), W900 series, W950 series, Z520 series,. Z530 series, Z550 series, Z710 series (Java Platform 7), Z800 series, Z525, Z500a, Z1010

2. Necessary Software

1. The J2SE Software Development Kit (SDK)

2. Sony Ericsson SDK

3. Opera Mini

Installation Procedure

1. First install JAVA JDK and then SONY ERICSSON SDK. Downloading these two things would be a little problem for dial-up users but there is no other choice.
2. Connect your mobile to PC via bluetooth or USB.
3. When the Sonyericsson SDK installed successfully, you should find a Connection Proxy icon on your system tray, otherwise Click Start > Programs > Sony Ericsson > J2ME SDK > ConnectionProxy to start the connection proxy which while active will show its status on the system tray.
4. Click on Settings icon (Gear). Select correct COM port for your connection. Choosing correct COM port would not be a big task. Open your device manager and you will find the com ports for your mobile USB/Bluetooth connection. Choose the lowest COM port apart from the COM ports that are attached to your system. Choose the BaudRate as 115200.
5. Now click Connect. You should see your mobile pic on the connection proxy saying that it is connected.
6. Open Sony Ericsson Device Explorer.
   Click Start > Program > Sony Ericsson > J2ME SDK > Device Explorer. You should see that the software is negotiating a connection with your mobile, and when successful, it will display a list of applications installed. In my case it displayed all the games installed in my W700 games folder.Important Note : If anyone faces error at this particular step saying “Malformed Response…… …. ” then it is due to some error in parsing the characters in the installed games. Delete games one by one in your games folder and Refresh the Device Explorer. It should work at some time..
7. On your Sony Ericsson mobile, create a new data account.
   For that, Go to Connectivity > Data comm. > Data accounts > New account.
   Account type: GPRS data
   Name: Anything you want. Leave APN, Username and Password empty.
8. Go to Connectivity > Internet setting > Internet profiles > New profile
   Name: anything you want
   Connect using: select the account you just added in the above step
9. Still in Internet profiles window, highlight the profile you going to use and press More and select Settings.
   In this window:
   Connect using: the new data account you just added
   Internet Mode: Http (already there)
   Use Proxy: No
   Username and Password: empty
10. Press Save to save this profile.Note: For broadband users under Corporate LAN, The settings are different. Use this profile settings.here.. Note the following…
    My IP address in LAN : 172.16.5.111
    DNS Address : 172.24.2.71
    Proxy server Address : 172.30.3.3

    create a data account named “broadband”
    ip address : 172.16.5.111
    dns address : 172.24.2.71

    create an internet profile named ” broadband”
    internet mode : http
    use proxy : yes
    proxy address: 172.30.3.3
    port : 8080

    streaming settings :
    connect using : broadband
    use proxy : yes
    proxy address: 172.16.5.111
    port number : 6082

11. Opera Mini InstallationDefault browser that comes with sony ericsson mobile just not mean to be used with this type of connection. You need to download other browser to be installed. Download the compatible version of opera for your model from its official site. You must download both jar and jad files. This is a quick download since the file is quite small. Now you can install Opera Mini browser by just rightclicking the JAD File you just downloaded and select “Install on Device”.
    When installation is successful, highlight the Opera Mini in the Device Explorer and click on “Play button”, or right click and select Start to launch the Opera Mini on your mobile.Note : Launching Opera Mini by using the phone itself will not work.
12. Now, If you are using Opera 3.0, it tests for network connection before opening the browser. If the connection test fails, check your settings once again. Restart your phone and try again. If everything is correct, i would suggest you to download opera mini 2.0. and proceed with the same steps above. Search google or download it from here ( Copy it to your phone and install from the phone since i cannot upload a jad file in my hosting site.)
13. Enter any URL in your mobile and you are done if you are able to see that site on your mobile..Note: Please do not expect that you will be succeeded in the first trial. There is every possiblity that you may miss small things. I have spent one complete day for the connection and then succeded.

Some Points to note:

1. Make sure “Serial Networking” is checked in device explorer.
2. Connection proxy is connected
3. Device explorer shows all the applications(games) installed on your mobile. If not, try restarting your device explorer.
4. If every setting is correct and still you are not able to connect to internet, restart your mobile
5. Use Opera mini 2.0 Advanced instead of latest version if you are not able to connect using it.

Why the hell am i doing this:

This post may seem a bit odd to you because who want to use internet in a cell phone if they have a broadband connection? Well.. here are a few applications for this.

1. You can access wap sites through your mobile.
2. In corporate offices with content based firewalls, this method provides anonymity to the users. (I cannot access orkut.com through PC, but i can do using my mobile )
3. Browse by staying away from your computer (Bluetooth )
4. You can also learn several features of SE SDK. I had never known before that an emulator in PC exists for my mobile.
