Jio join app or Jio4Gvoice app – Jio4GVoice app allows users to enable VoLTE in every 4G device. As we already know, Reliance Jio sim has been launched and it is working on 4G devices only. Reliance Jio sim requires VoLTE in every 4G mobile for making HD voice calling and HD video calling. But what is your device is 4G/LTE but not VoLTE ? then you can use 4G data in your mobile but cannot make any calls from your device :(. Don’t worry as you don’t need to buy a new device for making calls, you just need to download the jio join app from playstore which is also known as Jio4GVoice App.
Update – Jio4GVoice app always offline issue fixed.
