[Need Help] Not able to share 3G Data via "Mobile Network Sharing" topic

Hello Members,
I have opted for BSNL (India) 3G service recently and its working okay on HTC One E8 but after turning "Mobile Network Sharing" on, data connection is turned off. I have tried sharing via Wifi Hotspot, USB Tethering but am still unsuccessful in sharing mobile`s data connection with laptop. Any solution for this issue.
Advance thanks!!
