I am using tata docomo for a long time Tata docomo operators not provide good internet offer like airtel or idea.they give 1 gb free 4g data with new sim and also other offer.
1Gb for rs93 network to come it is a very big problem. they provide cheap packs not much costly like vodafone n airtel.otherwise docomo is good but network problem is big .
but someties network is not good in cities good but in village not avilable
