Airtel also has big leaps after spectrum addition in my area band 3 used to be below to 2mbps now it is always above 10mbps in download speed. Band 1 has increased from 10mbps to 25 mbps after spectrum addition. Band 40 is giving me 25 mbps which was same as before but there is no 40C enabled in my area neither they have changed the earfcn it is still 39150.😩 Airtel does some black magic in their network speeds have increased where they didn’t add spectrum but the mystery is speeds in b40 is the same . Overall it has become better so no complaints. Still the situation perplexes me🤣.
