IPhone 15 model number starts 5TL…

That is not a valid Apple model number, on your iPhone go to Settings > General > About and you should see the Model Number. It should be 5 digits, starting with an A followed by 4 numbers, so please provide us with that and we can tell you where your iPhone was intended for sale.

Your iPhone 15 was intended for sale within China mainland, Hong Kong, or Macao.

Oh thanks, just realized you can tap the Model Number to get both.

That unit was refurbished by someone other than Apple in an Apple-approved program.
