I have used airtel network for almost 2 to 3 years.but I am not satisfied with the service of company. They dont have strong network.sometime You would not get cellular network in your bedroom itself. And many times server as well as network goes down for some time. You can not call or use your data at that time. That is very annoying to me. The bad thing is that, If you need to talk with costomer service assistance they take long time to connect the customer executive.And in reply of our problem they say that due to maintainace resons our service is down we cant help you try calling later. So I personally dont like this network . But about speed of internet I will say it is the fastest network in india. Before some days ago I was not satisfied with the offers and plans. But now I will have to say that airtel is giving offers which are in very low cost. And I also want to tell you that airtel is only company which gives 50 persant cash back for next day. Another bad thing is that this company send to many massages and pop up massages after use of internet. So I conclude by saying that I personaly dont like this network. And also suggest you to go for athor network.Thankyou.
