Bharati airtel is not having a good network. They provide 4g data plan in 3g rates but whats the use of these because even in 3g we get 9 Mbps speed, which is good to stream high quality videos. Airtel postpaid connection give cheap traffic plan but they generate very high bill. Airtel is not provide cap on network thats why after completing of internet if u use data they charges very much. I was using airtel and my plan was 299 and they use to charge me 1500, telling that I was crossed my plan. ITS not a good network compare to other network like Vodafone in Mumbai. Now im using Vodafone and there bill are much more cheap compare to airtel.
