Guf15, technically you just need to create the Apple ID to download the international version of NBA app. From there you would use some type of VPN (many different companies out there). There is NordVPN with a 3 day trial. Once you get VPN, you will connect to India server. When it’s connected you would go to NBA.com and then league pass to purchase it for the year for (I believe) 999 rupees (Indian currency). There may be a promo code that drops it a few bucks but it’s cheap as it is.
One thing to note is that NONE of the apps (iPad & android) are functioning properly. Sometimes it works and sometimes it doesn’t. (More so towards the doesn’t).
But you have a computer or laptop that can connect to your tv, then it works all of the time. Just make sure you connect to Indian VPN server and once you are watching a game, you ca disconnect the VPN.
Hopefully this helps you and makes some sense.
