Also in about phone Bandwidth shows as UNKNOWN.

work done so far
1. Flashed Stock Rom - didnt work
2. rooted and changed Modem file - didnt work.

please help me out.

Thanks in Advance.
 
faced a similar issue with Galaxy S4 after downgrading it to Kitkat from lolipop. Installing the lolipop version modem fixed the issue for me.
You may just need to install the modem, which does not require you to root the device.
