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.
