"Wi-Fi Call" on the Zenfone 5Z



  • Hi christianrodrigues1981

    Thank you for your reply. I will forward the information to the relevant department. We will keep you updated and your consideration will be very much appreciated. Meanwhile, please check your inbox and provide me your logs and video for further checking. 😉

  • Christine_ASUS please also keep me informed about the next steps to enable VoWifi on 5Z. My case is identical to that described by christianrodrigues1981. Thank you.

  • Sure. I will reply here once I get any update news.

  • I too own this useless phone. I have waited enough for the VoWifi. I will take the OnePlus 7 that my son owns and use this as an iPod. Good for nothing phone. I was planning to buy a gaming laptop, but I will avoid any Asus product like plague.

  • Hi christianrodrigues1981 & vitorgn

    Thank you for your patiently waiting. After checking with the relevant team, we confirm that none of the Brazil carrier supports VoLTE and VoWiFi in ZenFone 5Z. Sorry for any inconvenience it may caused. 

    If you have any further queries, please do not hesitate to contact me with any record provided by Vivo Brazil for further checking.

  • Hi Christine_ASUS! 

    Excuse me, but not the operators that do not support VoLTE and VoWiFi on the Zenfone 5Z, quite the contrary, it is the Zenfone 5Z that has not been updated to support VoLTE and VoWiFi. 

    So much so that in Zenfone 6 VoLTE and VoWiFi works with the operator Vivo and has the wifi call. No operator would make available to its customers a function (WIFI calling) that had its own configuration for each brand and model of cell phone. 

    The configuration even exists on the 5Z, but it is not enabled, which only Asus could do, not the operators. The truth is that there is no interest from Asus in releasing this function in the 5Z. It is a pity!

  • Hello Christiane, in contact with my operator it tells me that the Asus enabled for voLTE are: ZenFone Max Shot, ZenFone 5 / 5z and ZenFone 6, technical support even guides me to enable a function on mobile networks, voLTE, but no I have this function, I believe there is an error in the software because this menu does not appear, shouldn't it be there? Contact by VIVO is by phone, only if you try to record the difficult call to prove it. I could see with your team why the option is not there in mobile network settings, my friend has a ZenFone 6 and the option is there, voLTE and WiFi Call even his operator does not support any of the features on ZenFone 6, thanks for your attention

  • Hello Christine, how are you?

    I asked my friend for a printout of his zenfone 6 configuration screen for comparison with that of the 5z because I may have expressed myself badly about the configuration not being present in the 5z software. His zenfone 6 the current operator does not support any of the features and the option is there, my operator informs me that the 5z is compatible and the option is not there, my question is only about voLTE. Have a great day. @Christine_ASUS

  • Hi Chris

    As I mentioned before, it depends on things like White List: Weather the carrier supports, or we have mutual agreement of, VoLTE with the model or not. Sorry for any inconvenience it may be caused. 

  • In India 5z support VoLTE for all carriers in India.

    But unfortunately ViLTE and VoWIFI both are disabled or I say not available for 5z in India.

    Infact ZenFone 6 and ROG 2 phones onwards VoWiFi is available in India.

    Don't know about the ViLTE situation of Asus.
