Reliance Jio has launched ‘Smart Coverage Map’, which lets you check the 4G network coverage in your area. This could be a great help for those users porting from their existing operator to Reliance Jio. All you need to do is login to the website Jio.com with your registered number and password, click on ‘Smart Coverage Map’ link and then enter your local pin-code. The map will then show you all the network towers near you and the network strength. Users can also send their feedback to the company through the site.
