After giving an unlimited free browsing for 2hrs yesterday, vodafone is dashing out 1 free gigabyte of data. All you have to do is download their app and register. After its done you get a 1 gigabyte free for browsing. I am posting the link below.
1GB free just for you! Download or login into the latest version of My Vodafone App to get a cool free 1GB. Simply click Link to download now.
Unlike the 2hrs free browsing, this one didn't have any expiration date attached to it. You were supposed to have gotten your 1gig of data after the registration. Do call their customer helpline to find out whether it was just for that day or something might have gone wrong at your end.
