There are one of top mobile service provider but for me for the area I do live there network are never there . Being honest network airtel is also not good in my area but with them they are super bad and it is not service most of the time with vodafone .
If you live in rajouri or in near area I will not recommende you to use vodafone . because there tower not is every where near that of any network is also very low on the streest .
I o recommend airtel even having compaint with vodafone as they are still the best .
