I have used this Airtel 4G LTE data card, it’s speed is excellent, without any intruption online movie/TV serial as well game I had watched. Data cost is same for 3G and 4G LTE. I have some question regarding Airtel network signal strength needs to imrove like Noida DND, Dellhi Metro(from Jawahar Lal Nehru Stadium to New Delhi Railway Stadium etc.), else it’s speed is too good. Thanks to Airtel to innovate such good technology. My recommendation is to use 4G for high speed.
