@vishal_k Yeah it was very good during the intial years, i remember during the 2018 year , when i was on airtel i used to get very good speeds with 2ca with b3+b40 , speeds were around 20 to 30 mbps even within my house, after they disabled ca i was getting 2 to 3mbps max on b3 5mhz. even though they reframed b1 , i only got b1 on a single instance and the speeds were of 20 mbps , so i am suspecting its on siso only
