I am using airtel from 4 years . I started my mobile use with airtel but soon I realise than it is very costly. I have to pay 123 rs for airtel to airtel 10 paisa per minute tarrif. But on other hand it is very chip in idea and aircel we can get idea to idea 10 paise per min tarrif at 9 rs for 90 days. But in airtel no tarrif will exist for more than 28 days and every tarrif plan is very costly.
We can get 1 gb 2g data in 98 rs in aircel but we will get 1 gb data in 198 rs in airtel.
But it os good in network connectivity so ai am using airtel.
