Not everywhere in Maligaon. After Jio, I started using Airtel (my 2nd Sim). Used for around 6 months. For first 3 months I was getting top notch speeds (1-2mB/s easily). But then suddenly from February (last year) the quality degraded drastically. I wasn't even getting 100kB/s. The next 3 months it was the same.. I complained several times. Then decided to Port to Vodafone. And till now airtel hasn't fixed it. Speed stays around 40-70kB/s.
