A:AnswerYes, you can switch carriers because it is "UNLOCKED", you may need to purchase a sim card to install. My phone was supposed to be new but, it had another provider's sim card inside but, I use Boost Mobile. Therefore, I purchased the boost mobile sim card and switched them out.
A:AnswerOnce you buy the iPhone is ready to be used anywhere in the world. You just have to get your SIM card and the phone will work anywhere you want.
A:AnswerI have a friend that his personal phone Right now is an iPhone unlocked from Mexico. He activated with a cricket wireless in the United States. The service and the phone is just fine. A couple years ago I went on vacation to Mexico for a full month and I activated my iPhone 6 with a Mexican cellular service for that period and worked just fine. As long the phone is unlocked I don’t see any issues that you could have to activate the new iPhone in Argentina. But I am not familiar with cell phones in that region. I’ll hope that this helped you.
A:AnswerIf you don’t have credit I doubt they’d give you any monthly deal? Which is probably doing you a favor in the long run. Nothing is free!! Remember that! lol
A:AnswerBox is sealed if you buy the default product. However if you want to pay less there are also phones with “open box” label which as the name suggests are not sealed, and sometimes they don’t have the original packaging materials. If you are going to buy an “open box” product I will suggest to stop at the store and check the conditions of the phone before buying.
A:AnswerYes if its an Unlocked one it will work with any carriers around the world, If you have an issue just go to the company that you use in other country ,they can just issue you a new sim card which can be of a different bandwidth which will work with your iphone, No Issues.
