I have been using airtel since the past few years and observed drastic changes in its network and its rates as well.
The signal quality and service is good but the charges they apply are very high.
It is very difficult to use it for calling without a rate cutter.Now, I am not using it for calling most of the times, I am using an alternate sim to make calls and I didn’t remove the sim is because all my relatives and friends have this number and will be problematic for me if I remove it.It would be so nice if airtel brought down the prices.
