I have been using airtel fibre for past 6 months , my plan is 6100 for 6 months plus only 750 setup cost overall its only 6850 for 6 months better than the other companies plan and to my amazement is speed is also great I will share screenshots of speed also and as a part of plan I got 1 year amazon prime free and zee5 subscription also free, they promised 100Mbps I got 70 to 80 Mbps and thats pretty fine and premium services are also very nice.
One more thing that 5ghz works like 5g and do the wonders
