Lucknow, Uttar Pradesh, 226016

I bought new airtel sim on which i got 1 gb 3g data for 28 days, now after getting activated when i connected it via wcdma mode having full network in my home firstly it took almost a minute to get connected and after the speed was very poor i could not even open google home page no browsing nothong i was shocked then i reconected it then also same problem i then connected it on my laptop via dongle there also full network of 3G but no response from host. When i switched to 2G then i was able to do browsing. I did a complaint regarding this on one of the stores they had noted my address and all details and said that representative will call u but its been 1 week and no sign of respone Phone no.
