how to resolve "no service" issue in my iphone 6 with ios 8.3 update??

Howdy Swamy,

If you are having an issue with "No Service" coming up on your iPhone's status bar, I would suggest that you troubleshoot using the steps in this article -

If you can't connect to a cellular network or cellular data - Apple Support

Thanks for using Apple Support Communities.

Best,
