Help s6 middle frame

[androidadmiral]

Hello all, I hope someone here can help. I need a new, to me, middle frame for my s6, I have seen many offered for sale but what I need to know is will a middle frame for another carrier or a frame from another country or region work with the rest of my phone? Thanks in advance for any help.

I'm just completely speculating on this so anyone else commenting with actual experience should take precedence, but apparently the S6 midframe does not contain components, like the SoC or the radio baseband chip, things that might be directly relative to whichever cellular network used by your carrier or country. Those still reside on the main mobo. That midframe does appear to contain the NFC/wireless charging component though (the large dark piece)

which I don't know is or is not specific to any particular carrier or country, so there is that. More details here:

Perhaps you can buy a S6 midframe that specifically matches your S6? Or would it be cost effective enough to just buy a matching, used S6 and cannibalize it for its midframe (...and you'll have a 'spare parts' phone for other, miscellaneous parts you might need later).
