Airtel is an network operator which is now one of the biggest operators competing with companies like vidafone and reliance but the rival companues are comming up with new schemes which can lead the customers to companies like jio and reliance so I think airtel should cut down the charges for calls and data besides that when we talk of network airtel has one of the best networks in mumbai I have been using airtel simcard for past 3 months but have never faced any issues so its overall a good trust worthy brand just needs a few improvements. Thankyou
