We all about jio voice 4g app. Its the calling app from jio, bcause of which we can enable to make calls from our jio number. All we need to do is just to install tha jio voice aap from the play store and install it in our mob and we are ready to make calls for free using our jio sim. My question is, can we use the jio voice 4g app with the jiofi device ? And if yes then how ?
