Airtel is totaly down in our area from last 2 months. I upgraded my Airtel sim to Airtel 4G LTE. But the problem was not changed yet. In 3G mode it gave a good speed before 3 months. Its average speed was 500-700 kbps in 3G mode. But now in 4G mode its average speed is only 50-100kbps. Its very pathetic experience to me. I complained to Airtel customer support many times but they are just assured me that it will be solved soon. From last 2 months problems are not solved. I recharged 399 pack but I don’t even use 100 mb in my daily limit of 1024 mb. So friends I think its not a user friendly 4G service from Airtel. That’s all about Airtel 4G
