What is ISM band frequency range in India?

So in reality a major portion of the 868 MHz LoRa frequency channels are in the license free 865 MHz – 867 MHz band in India. Seven out of the eight channels are in the license free band in India. So as things stand right now we are good to go with LoRa in India.

433 MHz is not license free in India . Only 865 MHz to 867 MHz and 2.4 GHz. You cannot use 433 MHz wireless devices in India.

Presently majority of wireless based PABX solutions available in the Indian market operate in 2.4 GHz de-licensed ISM band.
