It is a tri-series, and Nepal is also taking part. If you are from the sub-continent, then you can watch the matches on Fancode App. It is a mobile app, but you can cast your mobile screen on TV and then watch the matches on your television. The subscription fee is ₹399 per year (around $5).
There are too many streaming platforms for cricket nowadays, but I would say that Fancode is worth the money. Here is a comparison of various streaming platforms and their annual fees:
Fancode: ₹399 per year
Hotstar: ₹499 per year
Sony Liv: ₹999 per year
Prime Video: ₹999 per year (no sports, only movies and TV shows).
I have subscription to all these platforms on top of Cable TV. Subscription charges for various TV channels are as follows:

Star Sports 2 HD: ₹269 per year
Star Sports Select 1 HD: ₹269 per year
