I just tell about Vodafone network.
It is the best network in india. India have many networks like Idea, Jio, Airtel .
But I suggest Vodafone is best on all networks. Vodafone's network is available in all India or any state.
Best Internet provide by Vodafone .
Its 2G network is faster then other 3G networks. No any Internet problem or no any calling problem .
4G network of Vodafone is the best network in all india.
Some 4G price is costly but more efficient.
Best network for India
