I am using vodafone sins 2 years.the vodafone network you will get everywhere in india, vodafone has a good network coverage at everywhere and when I was travelling train that time also network was good while train running, and good speed of internet of 4g even 2g and 3g also.
the vodafone customer service some time good and some time not good, and the best things is wich I like mostlly the vodafone customer service help you in midnight also when you call.talking is good with respect and you will get your solution in midnight also that, s best things of vodafone.
the vodafone bill charge is too hight then other networks and recharge of intrnet are expensive also and call rate is also high then other network.
