What do you mean by “copy” - do you think it isn’t a real iPhone and instead is a counterfeit? While there are counterfeit phones, they usually run Android, not iOS. Go to Settings/General/About, and note the serial number.

Then go to this site—>https://checkcoverage.apple.com/ and enter the serial number.

You can check to see if it has a valid serial number. That is about the best that you can do. Check here, Check Your Service and Support Coverage - Apple Support

And from The “orange triangle gang” 😁.

For sure. The timing was interesting too. Three the same time, the fourth a minute later.
