Jio 4g good network provider in India.i have been using reliance jio from a long time and it provide good service even in my city.jio charge are very reasonable and everybody can afford it.jio is the fastest operater in the world to achieve 160 million subscribers in just 16 month.jio is improved a lot and now is the fastest network in India
As per to my experience the service of reliance jio is stables everywhere.in the case of airtel u may find low quality service than that of jio ( especially when u r travelling.)
