Evey time my mobile switch on a pop up massage to activate airtel money moble comes up.when I rejected to activate It should not apear next time.I think It is useful to those people who require talk time in imerjencies only.no one will use this app to send money to other, because there are many other options available which are absolutly free or cost very less than this app.such as sbi freedom, paytm, pocket etc.we get extra features with these apps such as reward point, cashback etc
