NGC Broadband is currently hands down the best ISP in Guwahati at least, if not the entire North East. Exemplary service with only 72 hours of total downtime in 3 years of subscription. Mr. Manash Sharma is the most professional accommodating service engineer around. NGC has also never disconnected my connection on account of late payment of fees & rarely ever calls you to remind you of a missed payment. Overall, very satisying experience with quality connection. Far ahead than any currently operating ISP in Guwahati. Excellent job.
