Airtel is known for its high speeds in Internet and providing after services.
I have downloaded **My airtel app** on my moto g3 and its showing all my datat balances Whether its of my broadband or my 4g in one place.
But when you compare the speeds b/w Airtel 3g and 4g, there is no much difference as per the advertisements.
I personally cant tell the difference b/w spees of 3g and 4g.
I only get 1-2 MBps whether in 3g or 4g
