Iam using airtel from years. a very old customer of airtel. I they didnt disappoint me till now.I liked there network . as its always full in my mobile. no network issues.
Plans are also very good.( iam using postpaid) . postpaid plans are better then prepaid. so use postpaid connection.
A great customer service. I visit there office at Sangam, vadodara. and the staffs there are very helpful. and so kind.
Yes, they will charge you little high as compared to new companies. but I can guarantee . airtel is better then others. in sense of service. I strongly recommend airtel. for a great network and for a great customer support.
