If your net usage is very high please don’t go for it.
Connectivity: Frequent connection loss in Dwarka area.
Speed: At times it is good but very frequently it drops to few kbps and it happens very frequently.
Availability: Internet services go down very frequently and they will charge you even for the non available hours. To add to your woes they even do not care to inform unless you call them. Today only their services are down since 4:00 PM and they will resume the same by midnight.
Overall. DO NOT GO FOR IT!
