Airtel is the best mobile service operator, which has won the trust of millions of customers for many years.My family.
I and most of my friends, relatives and acquaintances use Airtel only or in case they have dual sim phone they prefer to keep Airtel as their master sim.
It provides many attractive offers of talk time or sms packs, data packs, hello tunes and so on, its customer care is good enough and very quick and efficient to respond and solve your problem before or within given time frame.
You are using prepaid or postpaid you will be charged correctly as per your plan only, bills are clear enough, no hidden charges are there to confuse customer.Its network coverage and connectivity is also good.Overall my personal experience is too good with Airtel and I am loving it.!
