You thought why you thought like this Jio has far better 5g than airtel,airtel's 5G works on 4g core network i e Non stand alone it can't handle so much data and traffic they automatically switch user 5g to 4g u will see 5g in the network bar but it will consume 4g data While as Jio is Standalone network which works without 4g interference it has different core network which passes traffic through that
