    OLS_TheWho , Jun 1, 2018 :
    Dear OnePlus Community.

    Is any OnePlus phone able to use use VoLTE or VoWLAN in the network of O2 / Telefónica?

    I had a short google check and fond something similar to
    "All OnePlus phones could not use VoLTE using a SIM from Germany"

    Is this true?

    Thanks and have a great weekend

    Robert

    Oneplus hast to integrate the ims information so the phone can establish Volte with o2. Maybe the data for other german providers is integrated but not for o2 in os 5.1.5
    O2 is not the problem here...

    As far as I know, VoLTE is available with no German provider. Could be available, as OnePlus only had to include something, as already mentioned, but for whatever reason, it's still not possible. Let's hope that it changes..

    Don t work in Germany on any Provider at Moment. German. Providers have to certificate oneplus phones So they may use VoLTE. But they re not really interested, want to sell their own phones first.

    Well I doubt that because the Xiaomi m a1 is working. And xiaomi is definetly more Underdog than oneplus in Germany!
    People with T-Mobile seem to be lucky with volte

    Only some Indian provider and I think T-Mobile USA having working VoLTE since the Oneplus2.

    OnePlus just doesn't care about it for the rest of the world. All dutch providers support VoLTE, but not OnePlus.

    as Troy mentioned:

    I think it's totally the manufacturers fault that it's not integrated. Read an article on this a while ago that says as well, that the provider stated that it's not on their side anymore, and they opened their paths for all phone brands to use VoLTE

    O2 help text in English (rude/shrink translation [Original text in DE underneath]):
    Why does VoLTE not work on my Oneplus or Google Pixel smartphone ?
    Vendor has to register the "provide configuration" in firmware.

    The Smartphone has to connect to IP Multimedia Subsystem (IMS) of o2 on it's own. If there is no provider information present on the firmware, die to the fact that the smartphone vendor did not integrale the code into the FW, no VoLTE connection could get established.

    It is up to the hardware-/smartphone vendor to integrate all IMS provider configuration into the firmware.
    _______________________________________________________________________

    (original) o2 help text in German:
    Warum funktioniert bei meinen Oneplus oder Google Pixel Smartphone kein VoLTE?
    Damit VoLTE (und auch WIFI-Calling) funktionieren kann, muss leider der Hersteller des Geräts die Provider-Konfigurationen bereits in der Firmware integriert haben.

    Denn das Smartphone muss selbstständig eine Verbindung zum IP Multimedia Subsystem (IMS) von o2 aufbauen. Wenn diese Daten fehlen, weil ein Hersteller dies Provider-Konfigurationen nicht in die Firmware integriert (aus welchen Gründen auch immer), dann kann auch leider kein VoLTE funktionieren. (da das Smartphone keine Verbindung zum IMS herstellt)

    Es ist also Sache des Hardware/Smartphoneherstellers, alle IMS Provider Konfigurationen (am besten von weltweit allen Anbietern) in die Firmware zu übernehmen, damit VoLTE bei möglichst allen Smartphones funktioniert..

    There are different "ideas" regarding VoLTE.
    some people mention'
    VoLTE does not work for OnePlus Phones in Cell phone networks in Germany.
    in January 20016, OnePlus released an update activating VoLTE in our phones: https://mobil.teltarif.de/oneplus-volte-software-update/news/66929.html

    Even the new OnePlus6 does not support VoLTE as mentioned here:
    https://www.notebookcheck.com/OnePl...LTE-und-WiFiCall-in-Deutschland.307926.0.html

    there is an interesting sentence in this Article saying:
    "Für eine komplette Implementation müsste OnePlus Abkommen mit den hiesigen Providern schließen."

    Rough translation:
    "OnePlus ha sto cooperate with the provider in GE to get VoLTE supported."

    It looks like OnePlus is not that interested in getting these steps gone.

    interested customers have opened a petition here:
    https://www.openpetition.de/petitio...eutschland-von-oneplus-geraeten#petition-main

    I hope this would get them integrating the support in all OnePlus Phones being able to use VoLTE and WLAN calls!
