@ Saurabh Sharma

Your E3531s is a new version, its 3 serial interfaces should be supported by the option.ko driver in Mint17 but the direct ethernet interface is not, it was added to net drivers two weeks ago so will be supported from kernel 3.17.

Please do:
cat /proc/bus/usb/devices

and verify that option driver has bound to 3 interfaces. If it has then you should be able to use the dongle in ppp dialup modem mode until you get an updated kernel with driver support for the net interface
If option driver hasn't bound then you'll have to load it manually:

modprobe usb_wwan
modprobe option
