Hii friend today I am sharing my personal experience about tatadocomo mobile operator
This service is good for good plans and recharges like full talktime, 3g internet pacs, 2g internet pacs, rate cutters, min pic and much more the speed of 3g internet is good but not better than vodaphone and its not support 4g and main negative point is its network not working properly in roaming and 3g net is not working properly in roaming if you do not have budget problem than you can go for Vodafone
