I am using vodaphone sim for lst 2 years.The network coverage of vodaphone is very good.i get network in rural areas also.
Whenever I goes outside of kolkata I always use this sim because of its good network.but the call charge of vodaphone is very high compared to other network and the tarrif plans are also costly.the net speed of vodaphone is very good.but the net pack price is high.the coustomer support of vodaphone is very good.ovarall its a good service provider but plans are costly.
