Hi friends , I am using Airtel sim past two year.Now I changed to other network .While using this network, everyday I got call from customer service nearly 5-6 times , it is seriously annoying one.The network coverage also bad in my area.Any buddy called me , the call didn’t connect me, after some time I get missed call alert.The internet also slow, it takes more time to load.Incase we call to customer service , they are connecting call to the person.I used nearly two , but they won’t provide any special offers to me.
