Airtel is the biggest company in India. I think its a no. 1 company. I have a airtel sim since 2011 its been 6 years I have used airtel only because of its network but after 2016 the internet is been decreased. I stays in Dwarka, here airtel network is good but still the internet speed is very slow. Specially 4g speed is way to slower than 2g, I can' nt evem play online like clash of clans or teen patti. These app need just little bit of internet speed but still in airtel 4g speed, the gaming apps doesn't work. We all know how costly plans are there in airtel, there price is too high, but zero service. I have complaint many times regarding the slow speed, they always restart your phone, set manually network but nothing works for me. They are decreasing there standard day by day.
