I have been using airtel and jio and the internet speed is 30-80 kbps on 4G but after switching to IDEA I am experiencing 1.5 to 2 MBPS on 3G and 3 to 9 MBPS with good network quality and high speed internet.
the recharge offers are good and similar to AIRTEL AND JIO offers.
I have been experiencing good network without any laggind.
