Selvin Job :
I Purchased SONY LED Smart TV in which i want to connect mobile broadband through USB Dongle. My TV model Does not support Moblile broadband through USB. Rather my TV has LAN Ethernet which connects Internet through broadband.
Can i use LAN to USB adapter for Connecting Internet through my USB Mobile Broad band?
I.m not sure why you'd want to do this?
What usb devices the tv supports will depend on the firmware.
A lot of TVs like this have an optional WIFI dongle. why dont you get that and use your phone as an access point?
I know on android above a certain version you can use a USB host cable to connect USB devices to your phone. I think in theory you could connect a USB ethernet card and do it that way but its a bit of a bodj job.
The third alternative would be to get a router which has the option of a 3g backup.

I have no idea why you'd want to run a smart tv over 3g though.
