One of the biggest mobile operator ’Vodafone’ now has set its feet on the indian ground firmly. It has expanded to such an extent that it is going to release 4g .Good network coverage as compared to other providers . The backdrop is that it is way to expensive . It has good 3g and 2g internet packs . Almost never gets a problem .
But sometimes it lacks coverage inside the houses.
So I solely recomend this mobile operator .
