OK that makes a lot more sense now but I can't answer that, I'm not entirely sure anyone can. I have no experience with being in Cambodia or using service there so IDK. It works here in the US no prob.First, I really appreciate your response.
So let me go straight to my concern.
1. I really love Google Pixel phone especially its OS and I own one which is Pixel 4XL.
2. I live in Cambodia which Google Pixel Phone store never officially launched in. That's the reason it's not listed on network carrier and that's why I can't use features like wifi calling & Volte it's supported from Carrier end (According to Google Pixel team in https://support.google.com/pixelphone/thread/117202259/enable-volte?hl=en thread).
3. I found a thread ( https://forum.xda-developers.com/t/activate-volte-on-pixel-4xl-android-11-r.4163217/ ) which show how to enable VoLTE on Pixel 4XL with android 11 which cannot use VoLTE feature by using Magisk module to update/replace a configuration file which taken from mbns-mi9t.zip. I have tried with this method but it does not work because I could not file a list of carries in my country in mbns-mi9t.zip.
1. I really don't know how far your team can go but I wonder if your team could configure/fix this problem that Google Pixel team has tied. I think most Pixel device owner around the world has faced this problem as I have and force them not to use Pixel anymore. Last, I think all Pixel owners will appreciate if this problem had been solved.
