I use airtel network since 2013. I must this is best network for Internet. Airtel makes more stability on Internet. They gives use many new features like 4g and happy hours. About calling facilities I faced some call drop on my phone. Otherwise airtel is great network till now. Other telecom companies like idea, reliance, Vodafone they cannot touch airtel. Vodafone Internet is so slow then other. My friends tell me that they recharge on 3g net for Vodafone ?? they use it on like 2g speed. We customers and we have rights no know about network. Airtel starts open network compain to solve customers problems and be opened. I wish we get more cool features from airtel in future. Thank you for your development and excellent service to us.
