Airtel first launched vfiber in chennai. Fiber lines are not even laid completely. My friend got upgraded to the plan and its really speed and stable. I’m residing nearby his place like 500 meters away. The port for my connection is not upgraded. Speeds during night going nearly 45mbps which is more than advertised. uploads ranging around 5-6mbps. They’ll provide a huawei hg630a VDSL rourter compatible for v fiber. If you request an upgrade.
