@airtelindia why is it too tough for you all to launch some eye catchy 3G plans?? 3G not 4G since we comprise majority of your customer base...lemme suggest some..
21--300 MB--1day
51--1GB--7days
101--2GB--15days
201--4GB--30days
501--10GB--60days
1001--20GB--90days

and those asking for more data, they may opt for broadband services..
