Hi Team Asus..checked out Sept update for 5Z..no mention of Vo Wi-Fi feature seen in this update also. Whether Vo Wi-Fi feature will ever be available to this so called flagship 5Z??


  • Dont expect vowifi for 5z as it has completed its 2 years

    But, who knows never say never implementations totally depend on carriers so if they decide to add 5z to support list than 5z will surely get vowifi but chances are less now

    Just You can do is email carrier you use n do same with your region asus headquarters like if you are from india than email asus india as well so that they may notice user requirements and decide with the vowifi implementation

    Dear All,

    All answers in Indian Context.

    I had taken up the issue with Jio Care on 28th July 2020. Their response is attached herewith, which sounds positive for VoWIFI with Asus Zenfone 5Z. Please refer to the "red" highlighted box. 

    If few Jio Users can take this up with Jio Care ([email protected]), I think there will be progress, in terms of whether they can provide this feature or not. Atleast, knowing whether it will happen or not, will help to settle the issue, instead of needless expectations / follow-ups. Also, follow-up from a market leader like Jio and Airtel will help to present the case, better with Asus.  

    I have presented here the text, which can probably be Copied & sent to Jio or Airtel Care which will help to address the issue. Please do copy paste this or draft suitably yourself and send email to

    3. If you don't get satisfactory response, from care you can also write to Appellate Authority for better quality response. Please do not write to appellate for the first time, write to them, only if you don't get proper response from care.

    Dear Care Team,

    Greetings and Good Afternoon!

    My Mobile number is xxxxxxxxxx. 

    This is with respect to the Voice Over WiFi (VoWIFI) support for Asus Branded Handset Model # Asus Zenfone 5Z - Asus - Z01RD - ZS621KL - India Version. 

    Asus team says the Jio team has to finish the work whereas Operator's team says, please check the online link / for supported devices. 

    It would be highly appreciable if the your team can take the lead and initiate discussions with the Asus development team for the top 4 or 5 Asus branded models sold in India. Voice over WiFi is a basic necessity and it would be of great help if the your Team can really work with Asus to enable the VoWiFi support to Asus Zenfone 5Z and other 4 flagship models in Asus range.  

    My Mobile Handset Details #

    Brand Name # Asus Zenfone 5Z

    Model Number # ZS621KL

    Part Number # Z01RD

    Once again, it would be of great help if the Jio Team can really work with Asus to enable the VoWiFi support to Asus Zenfone 5Z and other 4 flagship models in Asus range.  

    Thanking you in anticipation.
