Yeah I know.
But the seller is insisting that it supports and one of them even said "for the new iPhone 17 its integrated in the camera control button"
I don't care what the seller said to get you to open your wallet. If you didn't buy your phone in the US, manufactured for the US, you don't have a phone which supports mmWave. I'm not aware of any other country which even supports mmWave transmission, so I'm not sure why this would be important to you, anyway? I live in the US and mmWave is built into my iPhone and I've never been in a location yet, which even accessed it. It's VERY short range and primarily used in Stadiums or Airports where there may be a LOT of people trying to use 5G service.
If it's really important to you have an iPhone which supports mmWave, return your phone for refund, hop on a plane and come to the US to buy your phone. Of course such a phone purchased in the US won't have warranty outside of the US, but it would be the only way you could buy an iPhone with mmWave. And a US purchased new iPhone would be eSim only, with no physical SIM card slot.
