Vodafone is the best mobile operator
I assure you will get towers of vodafone at southpole or north pole also
why people provide bad reviews I dont know but I like the vodafone the most
network coverage is awesome!
you will always find good network of vodafone at any places like mountains hill stations or any other places where other networks dont reach
in some villages all network you wont find but vodafone will find you
if you are tourist or business man and always keep in contact with people I recommend you to use vodafone
as a student vodafone is costly mobile operator but not as costly that you cant even afford
customer service is awesome and you can get your problem solution very quick
though data pack charges are too costly I dont recharge the data packs
but even if you recharge 2g pack, it will give you good speed that other mobile operators give
