Hello Gaurav3688,

  What phone are you using? Does you phone show any signal? Have you verified that it has bands/frequencies compatible with those used in India? You can view the bands/frequencies used in India here.

  Had you removed the SIM previously? If you did, you might consider re-installing the SIM again to see if its placement was an issue.

Hope this helps 😀

Cheers
