I came across a problem when to connect a Tata photon plus (Huawei EC156) Modem in Ubuntu. You can use the same method in fedora. By default it is not  recognizing in ubuntu. When I plugged in the blue light starts blinking but not taken by the default network manager . On ubuntu forum I found a solution. It works great.

First make sure the following packages are installed in your Ubuntu. In most cases it is default.
* usb-modeswitch-data
* usb-modeswitch

Unplug all other USB devices from the system. Connect the tata photon plus (Huawei EC156) and see whether it is detected automatically in the network manager. In most cases it is not.Open the terminal and just fire an lsusb. You will get a Huawei EC 156 connected to your usb.

ON Terminal

sudo gedit /etc/usb_modeswitch.d/12d1:1505
copy and paste the following code in that.
Code:
DefaultVendor= 0x12d1
DefaultProduct=0x1505 

MessageContent="55534243123456780000000000000011062000000100000000000000000000"
Save and close the gedit. Then type
cd /etc/usb_modeswitch.d
sudo usb_modeswitch -I -W -c 12d1:1505

You will get the output as

Reading config file: 12d1:1505USB description data (for identification)
————————-

Now your Modem detected by the system. Type in the terminal

nm-connection-editor

Create a new mobile broadband connection . Select Tata Photon Plus.

Connection NO : #777

Username : internet

password: internet

Create connection and save.

Select the connection from Network Manager dropdown.

It will be connected automatically.

In My case the range of the device is not showing. Except that everything working perfect

  •  No need to run a script everytime. In usb-modeswitch every entry in /etc/usb_modeswitch.d/ directory has a corresponding entry in the udev config file /lib/udev/rules.d/40-usb_modeswitch.rulesThe file can be edited to add the rule for 12d1:1505, the switching will now be doneautomatically
