Airtel is one of the best and biggest Mobile operators in India. Well, because of their large coverage they have become better. Internet speed doesn't matter in a place where coverage of every operator is low airtel comes in handy with a better network. Being an airtel customer I love it. Now talking about their customer service, Its Good I wont say Best but it does the job. But the only thing I dont like about them is bill. They are pretty expensive when it comes to the bills. I personally think they have to get some good plans for Postpaid users. Well, paying bills is pretty easy for everyone nowadays. Myairtel app is a perfect place for management of your numbers even family members.
I prefer Airtel over every other operator. I love it.!
