I think Airtel 48 Plan is cheapest from all operators who needs incoming, otp and regular upi transaction data usage. It gives 1 GB Data for 1 month validity. Plus it's giving Jio Hotstar Mobile for 1 month too.
Few weeks ago, there was a news came in official gazette from Trai that every operators have to drop those voice only plans by April 15th (this order was for all such as Jio, Airtel, Vodafone and Bsnl). Today, is 3rd May, and not a single order has been followed by any operators. Where is law and order ? Is Law and punishment just for public ? Why there is no protest ? Why there is no complaint ? Why there is no case or PIL in courts ? It's a open breaking of law by telecom operators.
