iphone 5 owner here since 2012. I'm thinking to upgrade to an iPhone 6s 4.7 but just have a few questions. I'm out of the country and currently traveling in South America until mid January, after that I'm heading to Southeast Asia. I'm with Verizon. If I do decide to buy an iPhone 6s from let's say Singapore or Hong Kong for example, will it work with Verizon once I get back to the USA? I think the 6s is worth the upgrade personally, but not in a rush to get one right away, but I would jump and buy one if I had access to an Apple Store, but not whole I'm here traveling in South America. It's so poor here they don't even have shopping malls.
