A:AnswerThis phone is sold Unlocked by Apple themselves, Best Buy at this time doesn’t sell an Unlocked version. The only unlocked iPhone that they sell is the iPhone SE2.
A:AnswerHello,
You can trade your phone in but it will be with Best Buy and what they offer for a trade in not AT&T. Go on to BB website and do a trade in calculation to see what you could get. Do the trade in first and use the gift card they give you on your phone purchase. If you want to do the trade in via AT&T you can mail it in but the trade in value will be different.
A:AnswerNo. If you choose AT&T, it is carrier locked. Carrier locked means that you can only use it on that carrier's network. Best buy does not have an unlocked option. If you buy directly from Apple (https://www.apple.com/shop/buy-iphone/iphone-12) you can buy the unlocked phone for $30 more than regular price. (That's the same price as from Cricket)
A:AnswerSure, you better hurry...based on timing you should be able to get $350 trade credit which will be applied to your bill. It may take upwards of three months to sort out the changes but I just traded-in a iPhone SE (2nd Gen) and got $350 reduced from the payment plan...Yippie. You'll maybe may one normal payment then the rate will change once the changes catch up
