Reliance Mobile Operator are the worst operator in the category. They have worst network and disgusting customer service. The customer care will keep on calling the subscriber unless an until you change your operator and will keep on sending SMS continuously.
Gone are the days, when they had plans for customers which were reachable for normal people also. But now they have disgusting service. The customer care will deduct your charges with no reasons.
Recently, they came up with the MNP service in which they asked the subscriber to latch on their network from other networks but after 3 months they stopped all their operation. Even they dont have their own networks in many areas.
Worst plan, Network and most important irritating Customer care.
