Configure and connect tata photon plus in debian 7

The 3G dongle of tata photon+ (Huwaei EC1260) might not work by default in debian 7, and other linux distros. Here is how to get it working.

The first step is to install the packages, if not already installed.

usb-modeswitch usb-modeswitch-data

sudo dpkg -i usb-modeswitch sudo dpkg -i usb-modeswitch-data

Once the two packages have been installed successfully, next we need to install wvdial

sudo dpkg -i wvdial

After installing the pakcage, insert the dongle.

Now open a terminal and type the command

$ sudo wvdialconf /etc/wvdial.conf

We will see an output as below

The fourth line from below recognizes our dongle as the device /dev/ttyUSB0

Next we need to configure the wvdial application to allow it use the dongle to connect to the internet.

For doing this we need to open the wvdial.conf file located in /etc/wvdial.conf

$ gedit /etc/wvdial.conf’

By default the file will look some thing like below

[Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 &C1 &D2 +FCLASS=0 Modem Type = Analog Modem ISDN = 0 New PPPD = yes ; Phone = < Target phone number> Modem = /dev/ttyUSB0 ;Username = <Type the username> ;Password = <Type the password> Baud = 9600

Delete the ";" at the beginning of the lines "Phone","Username", and "Password". and replace the three lines with

Phone = #777 Username = internet Password = internet

Then add the following lines to the file at the end.

Init3 = AT+CRM=1 Stupid Mode = 1

The edited wvdial.conf looks as below.

[Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 &C1 &D2 +FCLASS=0 Modem Type = Analog Modem ISDN = 0 New PPPD = yes Phone = #777 Modem = /dev/ttyUSB0 Username = internet Password = internet Baud = 9600 Init3 = AT+CRM=1 Stupid Mode = 1

Save the file and close it. Now go back to the terminal and type the command

$ wvdial --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 &C1 &D2 +FCLASS=0 ATQ0 V1 E1 &C1 &D2 +FCLASS=0 OK --> Sending: AT+CRM=1 AT+CRM=1 OK --> Modem initialized. --> Sending: ATDT#777 --> Waiting for carrier.

Now open a browser and start browsing.

Note that before running the command wvdial in the last step, turn off mobile broadband in the gui mode.
