Airtel is the best mobile operators.So many open facilities! Savage! It is mild-Jio.You can set a Callertune on your SIM with the Wynk Music app.It is generally set for one month and for free! English songs( rare) , Spanish songs( ultra rare) , Bengali songs( popular) and Hindi songs( common) .You can have data in the SIM too! Pay about ₹; 200 and you get 1GB data.Next you can install Airtel Thanks app to manage data usage.These SIM’s were originally made 3G but the 4G version has arrived too.I have an Airtel 4G SIM which is a Bumper Dhamaka offer.To retain talktimes, you must pay ₹; 49.5 or ₹; 50 as declared by Airtel.Other than that, this SIM is superb.Question your doubts hassle-free on Airtel Thanks app and get the answer without any objections on their side.Buy this SIM because they are on a mission of 0 questions and 0 complaints.And the young-generation can give good feedback.This SIM is simply a blockbuster.It is good for your trades too.Buy an Airtel SIM and pay ₹; 500 to keep a long talktime with data.Sell on Amazon by switching the data and receive orders on the SIM! Airtel SIM is helpful for me in various ways.So recommended every and one person to buy the SIM for a good feedback and 0 questions, 0 complaints.
