Thanks, based on your suggestion, AIRTEL seems to be the best option here as ACT will install the wire from very far point. Airtel box is installed just outside my building.
One more suggestion, I have multi device connected at the same time, Wifi Cameras, UHD 4k Dolby Streaming, Videos uploading to multi platforms and WFH as well.
Will 300 mbps plan Ok or should I go for lesser or higher plan.
