Hi, Whizz posted this reply a couple of months for a similar question:Currently, our partners in India are Vodafone India, TataDoCoMo, BSNL.Have a nice day!
Also Irene posted this helpful info:
Hi, I do not answer directly, however, be careful in India the frequency is different on my knowledge, since they have different models. Probably your phone will not be compatible.
Note that at this time for International Roaming, you can have access to TEXT and DATA, but NOT CALLING.
Its stated by Fizz here
You will not be able to make calls while roaming outside Canada and the US. Roaming calls (incoming or outcoming) will only be available towards the end of 2019. In the meantime, you will be able to use data, and send/receive texts when you travel outside Canada and the US. To make and receive calls, you can use messaging apps such as WhatsApp or Messenger.
BTW Is it possible you purchased the long distance calling add-on for calls to India? This Add-On is to be used while you are here (within your coverage area).
