Hey all, I live in the US and am on the AT&T network. I was wondering if the iPhone international models have a different model number than the US ones? The reason why I ask is that I'm wondering if the Mobile Hotspot feature is unrestricted on the international variant phones. They are unrestricted with Samsung Galaxy phones. I was unsure if iPhone handles their products in a similar way. (UPDATE) - I believe I found my answer. All the phones are the same and the carriers disable the Mobile Hotspot feature.
