After full two months, I finally gave up my laziness and did a quick search. I tried out the first solution offered and it worked out in the first try itself, how often does that happen. It took me a total of 10 mins including searching, restarting and configuring to get connected to the net in Linux.
Here is the procedure to get Huawei EC325 Data Modem in Linux:-
- Open a terminal window.
- Log in as root, i.e. type “su -” sans the quotes and enter the root password.
- Then use vi to edit/create the following file “/etc/wvdial.conf”.
- Enter the following text into it.
[Modem0]
Modem=/dev/ttyUSB0
Baud=115200
SetVolume=0
Dial Command = ATDT
init1=ATZ
init2=AT+CRM=1
FlowControl= Hardware (CRTSCTS)
[Dialer tata]
Username= internet
Password= internet
Phone=#777
Stupid Mode= 1
Inherits = Modem0 - In the above change the Modem=/dev/ttyUSB0 to what ever your device name is, you should be able to see it while the OS is booting, else give the “dmesg” command and search in that.
- Final step is give the command “wvdial tata”, and if everything is proper you should now be connected to the net.
- Press “Ctrl+c” when you want to disconnect.
I have tried this on SuSE 10.1 and it should work on any latest release of any Linux system. Also I had this system configured for net access for BSNL dataone service before, so am not absolutely sure if you have to do any DNS settings or not. But it should work regardless of it.
Great to be back into the Linux world again.

Hi nithin -

Hi Madwaraj,
I believe it will work without any re-installation, only thing that you may need to change may be the username and password. And of course the sim card

Hi, Nithin,
I purchaged HUAWEI EC 325 data modem from Reliance. They are cheating me with huge bills, I want to go for Tata Indicom, but I dont want to invest money on the modem, Can I use Huawei Ec 325 for Tata Indicom using Tsim Card that Tata Indicom will provide.
Please tell me whether I can use Huawei Ec 325 for Tata Indicom wireless net connection.
I went to Tata Indicom
and they are not sure whether Huawei Ec 325(purchaged from Reliance) will work for Tata using T sim Card, they are insisting to purchage HUAWEI EC325 (again)from Tata Indicome.
Please let me know ASAP.
thanks,

I tried your instructions on my Huawei EC325 USB netconnect Reliance card on Fedora Core 6 on my Sony Viao.
After a little bit of effort, smooth connect. Sometimes, initially I have to pull the modem out and reconnect. Also, I set up the modem connect on System/Admin/Network and that works fine too.
Next have to try it with my ZTE card.
April 30th, 2008 at 1:29 am
Ok.. I have just posted an article & tools for removing the lock for the device. Download the tool and have fun. It replaces the lock placed by network operator which disables the device to work on other networks. check out http://www.unpackstudio.com and see the article Unpacking HUAWEI EC 325 DATA CARD

Hi Friends,
I have followed the information from the reliance forum to use the modem in linux. There is a surprising thing. My modem is being recognized as gsm modem…
I am pasting the output of dmesg after loading the module using modprobe.
Please tell me what to do. I am usng mandriva 2008.1 and and quite impresed wth it. i am using kppp as an alternative to wvdial

Hi guys,
my problem is now resolved. i realized that it does not matter to me whether it is a cdma or a gsm service. all i had to do was configure it using kppp as a normal dialup connection.
