Hey guys, I'm traveling to the US from Canada, I'm looking to purchase a new iPhone X that is unlocked so I can use it when I return. The only retailer I can find that sells it brand new is Best Buy, the model number shows it as a Verizon model, even though it's listed as unlocked on the website. If I purchase this unlocked verizon model is it truly unlocked to any carrier world wide, or only unlocked in the US? Also this model comes with the Qualcomm Modem correct?
