The network coverage area is wide however while travelling in train there are no network at some places. In many villages the network is very poor. Extra services becomes activated itself and you will be charged with money. If you call customer service then they will decactivate it for you only three times after that if it gets activated again the money charged is not refunded. The charges for data pack are very costly. Its not sure that they will activate your data pack. The net speed sometimes is too slow to be called 3g speed. So be prepared before using this sim.
