How to Enable VoLTE or Use JIO 4G Voice or JIO Join App For Free Voice Calling on JIO SIM


Expires on 2016-09-30

VoLTE is the abbreviation of Voice over Long Term Evolution. In simple words, VoLTE enables mobile phones to make calls using the data. On the other hand, the traditional GSM technology has different channels to flow data and voice through their network.

The caller’s voice is converted in to data packets and sent to the other end, but it is reconverted back to voice before it reaches the receiver. There is no difference in the way you make calls, you can dial a call over VoLTE the same way you use to do on a traditional network.

Most of the 4Gphones these days have VoLTE support but this does not mean that all 4G phones have the capability to transmit voice over LTE. There are number of phones which have all the hardware support for VoLTE protocol, but have not received the required software update to activate the same.

There are 2 ways you can find if your phone supports VoLTE-
1) You can go to the link Above and check if your handset is in the list of phones.

2) This procedure will work only on non rooted Android phones with Lollipop and above.

Dial *#*#4636#*#* on the dialer app.
Tap on Phone information
Scroll down and check if you see”Turn Off VOLTE Provisioned Flag”
In case you see “Turn on VOLTE Provision Flag”, just turn it on in the same menu.

Restart your phone
Go to Cellular network settings and enable the “Enhanced 4G LTE Mode” toggle.

How to download and setup Jio4GVoice app?
The steps given outline how to use the Jio4GVoice app. In the next section, we talk about whether you need to use it at all.

First, install the app on your phone, using the MyJio app or install directly from the Play Store.
If you’re using a 3G phone, the app will ask you to connect to your JioFi Wi-Fi network.
If you’re using a 4G phone, it’ll use the 4G network to connect to Jio.
Once the app is connected, it’ll verify your Jio connection.
Then you’ve got to tap Get started to, well, get started.
Next, you’re asked to make Jio your default SMS app. You can just tap No on this message if you prefer.

Now Jio4GVoice is set up. You can use it as your dialler to call someone or send them an SMS.

How to make calls with Jio4GVoice app?
Follow these steps:

Tap on a contact. Now, just put your phone to your ear to start the call.
If you’re calling another Jio user, you can also “prepare” the call.
You can tap on the camera icon on the left to send an image, the location icon in the middle to send your location, or the urgent call icon on the right to mark the call as urgent, with a short message.
You can tap the video icon on the bottom left to place a video call.
Or you can tap the phone icon on the bottom right to place a voice call.

So that’s how it works.

I’ve got a VoLTE phone, do I need Jio4GVoice app?
No, you do not. Just use your normal phone dialler to call people. Jio4GVoice has some additional features, but it’s something you can easily ignore.

Jio4GVoice allows you to send an SMS to your contacts, or to call them. You can also connect multiple users with a bridge call, which is all stuff you can normally do. When calling someone, you can also press the urgent call button, which shows up on your contact’s phone so they know it’s not just chit chat. While in a call, you can also share your location, or share images, which sounds useful, but is rarely used.

My phone has 4G but not VoLTE – do I need Jio4GVoice?
As you probably already know, you can’t place calls on the Reliance Jio network, if your phone doesn’t support the VoLTE standard. Most Snapdragon powered 4G phones support VoLTE, and a fair number of MediaTek phones as well, so this is an unlikely combination, but if you happen to fall into this group, then you’ll have to use Jio4GVoice to make calls.

It works exactly as described in the first part of this article, and although we felt that the Jio4GVoice dialler is a little clunky, it’s the only option you’ve got here.

I have a 3G phone, is Jio4GVoice for me?
If you got a 3G phone, then you can’t use Reliance Jio directly on your handset. The workaround here is to get yourself a JioFi wi-fi hotspot and connect your phone to this. There are some drawbacks to doing this, as you’ll need to carry around two devices on the go, but it’s still an easier option than going out and buying an entirely new phone just to take advantage of Jio’s plans.

Getting a JioFi and connecting your phone to it over Wi-Fi means that your data is now being served over the Jio network. You still can’t use it to make calls though – and Jio offers fully free voice calls. The good thing is that the Jio4GVoice app allows you to bridge connections and use the Jio network to make calls, as long as your phone is connected to the JioFi hotspot.
