I would like to share my experience on Airtel 4G. I have been using it for 6 months. Compare to other networks, It’s recharge package is very expensive. When I got a recharge of 1 month, I got a okay of speed in it. But after one month later I wondered why not to raise the package. That’s why I recharge 3 months. They give me fine speed for the first 2 days. Two days later my phone started showing me 2G speed, I thought the network would be a problem right in a while. But it was not right then I would talk to customer care and they told me that we are sending the setting to you in a message, save that setting. But then the network problem was not correct. I ran my net with 2G speed for 3 months. After 3 months I changed my Sim and now I am using idea. So, I want to tell you for your good, you should not use Airtel sim. Because they are very useless in customer service support.
