Hello friends, I am an Airtel user. I have been using Airtel for the last one year. First of all, I bought BSNL SIM but I was not getting good speed of internet.Airtel internet speed is good in our area, so keeping the same number changed my SIM to Airtel. Now I do not have problems running the Internet and I have to go from one state to another to go to college. I get the range of Airtel even after changing the state.Airtel is India’s best 4G network.Thanks guys, hope this review will be like you.
