I have recently ported to Airtel 4G/LTE service after the pathetic experience of IDEA 3G. Airtel provides satisfactory service as compared to my previous subscriber. The company is vehemently campaigning for its services. The only problem that I have personally experienced is the huge difference between download and upload speeds with Airtel 4G/LTE. The upload speed is just a fraction of its download speed. The Airtel should also bet for its upload speed challenge like its doing for its download speed.
