Happy to share my wonderful experience of TATA PHOTON+ data card.This is the one which could live upto what it promised to give. OUt of 600+ logins, the failed logins were meager 20 - 30. Speed though not 3.1, is quite OK . tested it at different locations in Hyderabad . Though it is little expensive, with fast adding subscriptions it will have good performance chart in the coming days.
