Looks like a bad luck for me as on my side it just stupidly refuses to work no matter how hard I tried (reboot the device, nuke all connection settings and do it over again, adding ims and your suggested xcap APNs). The carrier is also Viettel. I'm very hesitated to call Viettel customer care to give me a hand because most of the time I called them, they have absolute no idea about how my mobile subscription really is, the service status in different areas, etc. All of those calls unpleasantly resolved as "try again later". If you can, please attach your
to help me better troubleshoot this out. I'm sure these won't reveal any of your sensitive information. Btw, does 5G work on your Pixel 6 too? Thanks. |

Though not related to the Tensor Pixel(s), I can confirm that this also works with the Pixel 4 XL, but only for Viettel for some reason. I couldn't get Vinaphone to register the IMS despite already adding the xcap and ims APN profile. And even then on Viettel I couldn't verify if VoLTE was even in action or not (the IMS Status screen shown different results compare to Tensor Pixel(s) too) |

Hi @ducnc1201, I'm using Pixel 4a 4g with Mobifone and need help to enable VoWIFI because of unstable carrier connection at my location. I already enabled and tried VoWIFI on Samsung phone and it's worked but not working on Pixel 4a 4g. Thank you. |

I'll add this to the docs, just confirming that VoLTE works and VoWIFI doesn't work, correct? |

Hi @kyujin-cho, thank you so much for the tool. In the place where I live, Viettel have turned off 3G before 2G, and the call quality with 2G is not good on the Pixel 6, so this tool saves me a lot of headaches with phone calls.
I have tested the tool on my Pixel 6 G9S9B with Vinaphone and Viettel, both in eSIM and physical SIM.
At first, they works without any configuration, but I noticed that they sometimes become unregistered when I'm going out, even when adding IMS profile to the APN.
But I has a Samsung phone laying around, and noticed that they usually have a XCAP profile in addition to the IMS profile, so I added it in, and it has been working flawlessly since, no sudden IMS unregistered.
Viettel don't support VoWiFi at the moment, Vinaphone do but I can't seem to find a way to make it work.
The XCAP profile is similar to IMS profile, APN and APN type as xcap/xcap.
