Airtel 4g LTE is really so fast than the other 4g operating system. I personally using Airtel 4g LTE on my smart phone. And it really so speed. Also net certifier only also certifier airtel 4g as the best speed in market. Also the company has a vast spreading network all over the India One can find everywhere its strong network wholeover India.
It gives maximum speed when I am browsing or downloading anything it works just like dropping the eye and open it. So I prefer Airtel 4g LTE every time and recommend everyone to use Airtel 4g LTE.
