hey, guys i found up a airtel trick that works over a zero balance. in my area i having a 2g network, but you can also check this on 3g network.
first of all you need a airtel sim with zero balance.
now in a your mobile make a apn settings to airtellive.com.
then download the latest version of "your freedom" app from play store.
after installing app, open it and click on the "configure" button on theright bottom.
then click on a "account information" , register up a account and then get back.
then click on the server connection,
set your freedom server: airtellive.com
connection mode port: https(tcp), then go back.
then click proxy settings, put proxy address "ems14.your-freedom.de" and port 8080
after that get back on the main screen and click on "start connection".
and it's done.
let me know if this work for u or not..
