    Anyone using OP5t with T-Mobile SIM (in Europe) and VoLTE/VoWIFI enabled/ working? What about VoLTE support in Europe?

    I asked 1+ support regarding situation in Czech Republic:
    "After careful analysis by our team, it has been determined that we do not officially support VoLTE with this network in your region. We hope you understand."
    No comment...

    VoLTE needs to be enabled by both carrier and OEM in agreement and certification.
    Only T-Mobile (US), Jio Reliance (India) and Air Tel (India) have have VoLTE enabled for OnePlus 3/3T and 5/5T

    Can confirm BT in the UK has enabled VoLTE and VoWiFi now, it now says (HD) next to the time while in a call now too, see top center icon.

    As said though, even if your carrier has enabled VoLTE, that does not mean you can use it with your OP device.
    For it to be fully enabled, both carrier and OEM have to met and agreed criteria and certification.

    While being called it's now saying "So and so is calling via WiFi" while I was indoors connected to our router, so I do indeed believe it's working.

    My "sources" told me that some certification is necessary indeed. But if OP don´ t cooperate with carriers in Europe at all.. Hopeless situation.

    @You Schmuck! I checked with another UK user on EE (BT) and they confirmed that they too have VoLTE
    So it looks like it is available with BT in UK
