Micromax 3g datacard MMX377G is released with three important operating system (Windows / Mac / Ubuntu) support. This Modem is coming with good and handy user guide. It has information about installation for all three different operating system. I like describe few picks of the Ubuntu installation from user guide.
Micromax dongle is coming with installation packages as inbuilt. We just need to install the package using following steps.
1. Pre-check before install the software
Insert the SIM card into the 3g dongle and plug the device into your computer or laptop USB Port.
Now check the plugged device using following command. Open your terminal (ctrl+T) and enter this command.
Above command must be return the all devices the SCSI-CDROM’s that mounted on your machine. You may get the below result in your terminal
If you have more than one device connected you may see like below. To confirm which one is correct device that linked with your dongle. We need to unplug and execute the same command and see which device is disappeared from previous list. Then re plug and execute the command, now you can see that device back. Your current device maybe linked with /dev/sr1 or /dev/sr2 or anything else.
/dev/sr0 /dev/sr1 /dev/sr3
There is another case also, when you run ls /dev/sr* comand you may receive the following result. If you get this message, the software is already installed. We will see unintallation step at last. If you are not getting this message no problem go with step 2.
ls: cannot access /dev/sr*: No such file or directory
2. Mount the device.
Navigate to users Home directory in your terminal and enter the following command to mound the device.
>sudo mount /dev/sr0 /mnt
It will prompt the password, after entering the password you should receive following message
