Want Rs.50 talktime for free…Who doesn’t? Facebook is giving away Rs.50 talktime to every new Indian user signing up via mobile. To avail this offer users need to register from m.facebook.com/tt. There is also something for existing users, if you refer to someone and he joins facebook then you can also get Rs.50 talktime. Facebook is quite popular in India and it is the second largest user base on Facebook. Also India has most number of users accessing Facebook via mobile so such offer is going to be good for Facebook as well as Indian users. I would say smart Facebook.
