I just recently got a Airtel 4g Sim. I switched from another provided to these guys because I had a problem with the speed everyday after 6 in the evening. My experience has been nothing better, if not worse. They promised a minimum of 5 Mbps but believe it or not, right now as I write this, I checked again on speedtest.net and I am getting 0.12 Mbps! When I checked with the customer care, all he has to say to it is, If it is displaying the connection type as lte airtel and it is showing at least 2 sticks, I must get the minimum speed of 5 Mbps. It is displaying Airtel with 3 sticks. But this is the speed I am getting. And yes, I am 1 km from Indiranagar Bangalore. So the excuse of no network area should not be assumed. Think again if you are considering their service
