Differences between Note 10+ 512 5G models

[geckoasiks]

Hi, I'm wondering if anyone can explain the differences between these three Note 10's?

SM-N976BZKETEL

SM-N976BZKEOPS

SM-N976BZKEXSA

All are Black Galaxy Note 10+ 5G phones but what are their differences please?

I believe all are 512 GB as well.

Thanks in advance.

Regards.

Mark
