Please help me regarding understanding the plan

Hi everyone I’m from Punjab

I have normal tv with DTH(₹400) connection (Tata play)+ wifi(₹700 /70mbps unlimited netplus) and some ott plans for mobile like for jiohotstar(100₹ per month) and Netflix(150₹ per month) also 2 Airtel sims where I do recharge of 220x2(which give unlimited calls +3gb data per month) so total gives around 1700+

I was thinking to buy a smart tv and a Airtel xstream fiber connection this festive season. The plan that I though was of 999 which give ott like Netflix jiohotstar +other + voice and call) the Airtel internet speed is very great in my area

Can someone explain this pack should I do it or any other better options
