I'm struggling to find an answer to this question anywhere online. Most sites don't specify how many physical slots there are, but some youtube videos show that models exist with 2 nano slots (could be honk kong models). Does anyone know? The apple support website mentions that iphone X and newer all have dual nano sim slots but I just tried this with an iphone 12 (which should work according to them) and it doesn't have both slots. Can anyone confirm?
