Hi!
The iPhone all use the same sim card size (nano sim) and you can swap from a 12-13 to a 5 or 7
Also, I want to let you know that if you have a sim card that says 5G or something like that, you can put it into an older phone, like the iPhone 6 for example. If you do that, you will get Coverage, but not 5G speeds. I know its an interesting explanation, but it saves the confusion when you go to pop in the card
