Even with some flashing/MSMtool/logkit/code/unlock/root, is it possible?
If Possible buy an Unlocked Version from Europe, China or India as Bootloader cannot be unlocked on an Carrier locked device from T-Mobile or Verizon.
Move to Oxygen OS 12.1 Global that supports 17 5G SA & NSA Bands, however with flashing other region firmware will not support carrier features like VoWiFI and VoNR and ViNR services.

It is unfortunate that it is extremely difficult to get dual VoWifi with latest oneplus phones in US. Even esim support would get the job done.
So the international version Cph2415 which has all the t-mobile bands support volte and wifi calling?

wait... you sure? Do you have any reference or did you buy a cph2415 and test it out? Is it T-Mobile only, or also ATT and Verizon and MVNOs?

All G965U and U1 models have locked bootloaders. There is no way to enable OEM Unlock.
You can't use G965F files on it since the hardware is completely different.
Always check for VoLTE compatibility before buying. The G965U/U1 is intended for US markets only.

so your phone was not sim unlocked so you may face issues if you crossflash, besides thats a great question about volte and thats a mabey since wifi calling and volte are more software specific. I do not know this so youll have to test out and see.
I have a S23U(S918B/DS) in China, but there is only 4G can be used. Flashing a third party SoulRom based on Mainland China version can use 5G, but I don't want to root my phone. Can I just Odin flash the Chinese version baseband instead of the whole firmware? The 5G Specs of 918B covers all the 5G bands in China, is there any service code to unlock the SA/NSA mode or more 5G bands in hidden menu?( I've tried S918U service code but it doesn't work for S918B)
Many thanks!
Have you tried the samfw tool method?
Does trying to dial below do anything?

Then check the band csc changing thread. You may need to flash the US firmware, then enable secret codes then enable all bands. You might then be able to flash back, if you want, and all the bands may remain open.
5g overrated anyways. Lte is better.

Did you have any luck with this? I travel between China and the US a lot, and I am wondering if I can get 5G in both countries with the S918B/DS on Verizon & China Mobile.
I just bought US model of s23ultra, but I actually live in Taiwan
the issue is none of it's the carrier aggregation is supported here
so I wonder if it is possible to flash SM-S9180's firmware on SM-S918U1 device ??
if it can:
1. Can I get future update by OTA??
2. Will it break Knox??
if it can't, is there any other alternative way to change the the carrier aggregation setting ??

Don't do it. You will brick device.
You can't flash U or U1 phones to B models it will brick your phone.
To enable carrier aggregation, check this thread
