Airtel is a known data service provider.With it you can enjoy internet at a very fast speed.Althogh, the data prices are high earlier, but now due to competetion with jio, like all data service providers airtel has also decreased its prices.Now, i am telling all of you a new scheme by airtel.Now you can get unlimited times 4G data by just dialling a number-52122.After dialling this number you will get free 1G.B. 4Gdata but keep in mind use this data in only 4G or LTE mode otherwise your main balance will be deducted and also before turning on the mobile data check your balance first as whether you have got the data or not because this scheme is available in only some states.So, enjoy it.
