Connecting MTS Mblaze USB Modem in Ubuntu

I recently bought myself an MTS Mblaze wireless USB Modem. Connecting it on Linux was difficult because there was practically no tutorial for MTS USB Modem, while many were available for Reliance and Tata Indicom Modems. So here is what I did to finally get it connected (Note : Execute all commands as ROOT )

i) You’d have to install the package USB-ModeSwitch. It is available here :

Note : When you open the above link, you should check out its dependencies and also install the dependency package ” usb-modeswitch-data”.

Just download and double-click on it to install the package.

ii) After you’ve installed usb-modeswitch and usb-modeswitch-data packages, reboot your computer.

iii) Connect the Mblaze Modem and wait for 30 seconds. While you’re waiting, the usb-modeswitch package is doing magic in the background, you can check the status through the following command :


iv) I hope you have “wvdial” pre-installed on your system. You can check that by typing “wvdial” and see if the computer recognises it. If it doesn’t then you’d have to install it. Its easy, refer this link.

v) Now edit the file /etc/wvdial.conf (If it doesn’t exists, then create it) as Root and copy paste the following code :

[Dialer cdma]
Stupid Mode = 1
Inherits = Modem0
Password = mts
Username =
Phone = #777

Init1 = ATZ
SetVolume = 0
Modem = /dev/ttyUSB0
Baud = 115200
FlowControl = Hardware (CRTSCTS)
Dial Command = ATDT

Note that ttyUSB0 may be different for your system. However, first try with the above code, if it doesn’t works and says some error like “ttyUSB0 doesn’t exists” or something similar to it, then find out the actual one by going through the output of following command :

dmesg | grep -e “modem” -e “tty”

vi) That’s it, you’re done. Now start browsing with the following command :

wvdial cdma

As soon as you start seeing some IP addresses, you’re online! DO NOT close the terminal in which you executed the command, otherwise you will get disconnected.

And from next time, you don’t have to it all over again. Simply connect your modem, wait for 30 seconds and type the last command. To disconnect, goto the terminal, and press Ctrl + C.

Hope it worked for you, if any problems occured, you can leave a reply !
