Not good. Review on Airtel Mobile Operator

Hello all, as we all know Airtel promoting itself that is Airtel is the most fastest 4Gnetwork in india but I will surely can say it is not at all trur. From last 5 years I am connected with airtel.i faced lot of time range issues with Airtel. If they are giving faster internet but not providing range for it what will be the importance of that 4G network freinds you can think. I personally felt this problem thats why I am using other network. I experienced another problem with Airtel like its network connection not continuously work sometime it is convert into 4G and sometime it convert into 3G. If want to say about customer service it is good.i didn't faced any issues with them in my 5 years experience. But their data plan is very expensive and they did not give proper networking service.so my suggestion to all of you don't go for airtel in a market other better options are available which is giving all better services than Airtel.thank you.
