VoLTE, VoWIFI and 4G+ signal

edited September 2020 in ZenFone 5 Series
Model: ZE620KL
RAM: 4G
Firmware/APP Version: 16.0615.1912.115
Frequency of Occurrence: Always
Rooted: No
APP Name:

Hello! I would like to know why the phone does not support VoLTE operator MegaFon PJSC in Russia (for the operator PJSC MTS, everything works)? The operator said that this function should work on all devices with VoLTE support. The same problem with VoWIFI. I also want to note the fact that the phone has ceased to steadily keep in touch with the 4G + signal, very quickly changing the status of the signal to 4G and vice versa, the signal also periodically breaks. There are no such problems on the other device (the test was on the same SIM-cards).
What could be the cause of all these problems? Reinstalling firmware did not help

  • Hi filev73,

    Please be informed that the support of VoLTE/VoWiFi may vary by country and operator.
    After confirming with relevant teams, we regret to say that VoLTE/VoWiFi is not supported on ZE620KL with Russia operator MegaFon.
    Thanks for your understanding.
  • Hi filev73,

    For the feedback of 4g+ becomes 4g sometimes, could you tell us what the comparing device is?
    The signal breaks, do you mean it disconnects? Does it affect your use in any apps?
    What is the approximate location where this happens? Are you in any building/ on a transportation/ in the basement/indoors or outdoors? Please check in other locations as well.

    Thank you :)

    Hi! The signal does not break, but it is the 4G + network that switches sharply to 4G and vice versa. It is observed everywhere, including the street. This affects the data rate in the mobile network (4G has a very low data rate)

    Hi filev73,

    Have you tested your SIM card in other phones, and check if there is a same problem?
    Could you tell us which device you tested on?
    Were you using any apps or performing any kind of actions when this happens that may affect your use?
    Thank you :)
