Yup Airtel ... but JIO broke the ultimate monopoly ... Still remember i used to recharged my phone with 1 GB of 2G speed with rupees 199/- ..... 2016 was Game changing Year, first time my friend got new 4G phone and JIO simcard .... we gathered every evening in the playground of society just to use his unlimited 4G data with speed around 4mbps ..... 😂😂😂😂😂😂😂 He bragged a Lot for that
