Airtel mobile operator is very good is a very good operator I have used this and I got a nice response from it the network of Airtel is very good but sometimes very less signal I got but that’s ok the speed of net is also good and customer servicing is good but not all time sometime it take too much time to connect with server but now it’s not like that that was before and I like a charges and billing function of Airtel mobile operator that when my some data is left and validity is gone so when I recharge again they will give my leftover data by adding on that recharge amount and that’s pretty good . So thank for reading.
