I don't want to give these kind of feedback to airtel but before one year I totally fed up with there services.
Earlier It was India's fastest network but now a days for me airtel should work on their services.
I called many of times customer care they people didn't give me the right solution, everytime they tell that we are working our network. If it is India's number 4G speed provider, so in Delhi ( which is capital of india) here I'm not getting good 4G service. How can I trust it other state of india.
I would suggest you people if you are not using airtel and thinking to use airtel 4g so please check in your area how airtel working then go through it.
