According to the GSMA deployment map it does not look like any network provider has deployed LTE-M or NB-IoT in India, unfortunately.
However, it looks like Reliance Jio had plans to roll-out NB-IoT in January 2020, so you could try contacting them to ask about the status of this and if there are any deployed base stations in your specific area.
ok got it, I have nrf52840 also, gonna try on that. thanks for your help. one more thing just for clarification, as we can use nrf9160 as nrf52 board(Using Switch), will it work IoT SDK on nrf9160?

I suppose in theory, yes the nRF9160 DK can be used as an nRF52 DK.
However, first of all, you wouldn't really have any GPIO pins. Additionally, you would have to modify the code, so it can run for the board's schematic. So I wouldn't really recommend doing it this way.
