Steps to Solve Jio 4G Voice Offline Problem

  1. Most of the mobile companies provide VoLTE for sim slot 1 only. So insert the jio sim in port 1 & check if it’s showing volte near tower symbol. If it does, then you should not face any difficulties while making calls through regular dial pad.
  2. Now, what if your phone doesn’t have volte? To come over this problem, Reliance has launched Jio 4G Voice app. With this, you can call to any network in India provided that Jio mobile data is ON.
  3. Firstly, turn off your phone.
  4. Insert sim in 1st slot & turn on mobile again.
  5. Go to settings > Mobile networks & click on ‘search network manually’.
  6. Wait for a minute & it will show you 7-8 different network.
  7. You need to select Jio 4G.
  8. Once you are registered on network, install/open Jio4GVoice app.
  9. It will show you offline status.
  10. Now turn on mobile data of Jio sim.
  11. Jio 4G Voice will start connecting to network & once the connection is established, it will show you status as call not going
  12. This should solve your ‘jio 4G voice offline’ or ‘call not connecting’ problems.

Jio4GVoice Offline Solution 2

I tried this method & it did worked for me. Jio voice app shows offline when there is no internet connection. So just switch to Airplane mode from settings. If you are unable to find that option, simply restart phone. Then wait until Jio receives signal. Now turn on Jio mobile data & your Jio4GVoice will be online within next 15 seconds.

Working Solution 3

You have to understand the fact that, Jio voice works only when jio net is enabled. If you try to make it online using airtel or idea internet, it will surely go offline.

Make sure that your wifi is turned off. If it is on then Jio4Gvoice will show offline status.

Still My Call is Not Connecting

Even I have faced this problem multiple times. When I dial any number & hit call button it gets disconnect immediately.

So to fix this problem, you need to call that number 7-8 times & keep calling repeatedly until it re-connects.

Why I’m not receiving sms on Jio sim?

It clearly indicates that your phone is not VoLTE supported. So you just follow these guidelines to fix the issue.

  1. Install Jio4GVoice app from play store or update existing app to latest version.
  2. Now it will ask for several permissions for calling and messaging.
  3. Grant all of then else some functions will not work.
  4. Now while checking sms, do not open your default inbox.
  5. Instead, the sms which you are going to receive can be seen on Jio4G voice app itself.
  6. You have to use it for sending or receiving sms through Reliance jio sim.

If above methods are still ineffective for you, then only one option remains. Search for old jio4gvoice apk file on Google and download it in your phone. Nowadays many mobile manufacturers are rolling out updates which eliminates the need of jio voice app. For example, earlier Redmi 2 users had to use jio4gvoice in order to make outgoing calls & receive sms but after the latest system update, there’s no need to use any such app.
