How to enable VoLTE in Android M ?

VOLTE-Android M

After upgrading to Android M, have you ever noticed if  VoLTE is working or no. Give it a look, if the function is missing , do not panic. It’s not that VoLTE is flushed out while upgrading, It’s just that, you need to enable the function.

How to enable the VoLTE Function, is a simple process. Just try this once :

Those who were using VoLTE on their devices before upgrading to Android M, were slightly disappointed to find that after flashing the upgrade, VoLTE was no longer there. Some were re-adding the feature to their carrier accounts and having to reboot their phones numerous times just to get the option back. others were just trying to get used to life without simultaneous voice and data access. Now we know that process isn’t necessary anymore and that there’s an easier way to get the option to show up in settings again.
  • The first step is slightly confusing, in some it may work , and in some it may not
  • Just type in dialer  *#*#4636#*#*
  • You will get 4 Menu Options : Phone Info / Battery Info / Usage / Wi-fi information
  • Select “Phone Information” from the menu that shows up
  • Scroll down and select “Turn on VoLTE Provisioned Flag”
  • Toggle Airplane Mode on your device
  • Check “Cellular Networks” under the More Wireless & Networks option in settings
  • Happy ending

      For Intex 4G Devices try the steps below ( though VoLTE Voice does not work on Intex Devices, Only Data works )
      1. Go to Settings
      2. Enable VoLTE
      3. If still not working, Edit APN Access Points for Jio
      > Name – Jio
      > APN – Jionet
      > server –
      > save the settings and quit APN
      > still not working , change APN Type to ” ims “
