I am using Airtel sim card since I owe my first phone and till date have used their 3g services always.
The speed is good and fast. When 4g Airtel came.
I took a new 4g simcard without which it does not work and although the performance is good I think, is it really 4g or is just simply claimed to be? My 3g also gave such speed and in 4g.
I am getting a little more than it but not always. Many a times I am facing Network issues and my data network is not there. At times my sim is shown unavailable which is irritating as have to register it always. The data consumed is much more even for surfing. It is such a hole in my pocket that I was happy with my 3g connection. Why to pay more a little extra speed than 3g for 4g. I guess Airtel has enhanced and improved the speed of 3g and named it to be 4g claiming it to be the fastest, which is not true
