Hlo guys .i am ashish and today I share my personal experience on airtel 4g network. I used many sim cards to get a best sim card which provide me a best network and internet speed. My friend told me about this sim so I bought it. It is costly very expensive but as cost wise it did not work. I was very disappointing on sim card. It left its network in city. It was taking so much time to load a normal page. In first days it worked properly. But some time later it was disgusting. I contact to the customer care also they told me to change my prepaid connection to postpaid. They promise me to solve this problem by change my sim card into postpaid. So I changed it to postpaid but the problem was as it was. So I changed it and took a new sim card idea 4g. So guys dont buy a airtel 4g network. Thank you
