Can I just put my SIM into my new Samsung Galaxy S9?

Samsung Galaxy S9

Episode 1545

Patrick from California

Patrick bought a Samsung Galaxy S9 at Best Buy for Black Friday. Can he just drop his SIM card in or does he have to get it activated? Leo says he should just be able to drop his existing SIM into it and get started. Leo says that the FCC doesn't like carrier locks if the carrier isn't subsidizing the phone. So all he'll have to do is call the carrier and ask them to unlock it, if he needs to. But if he's a Verizon customer, it shouldn't be locked at all, and since he's not switching carriers, it should work if it uses the same SIM.

Mark from Thousand Oaks, CA

Mark ordered an iPhone X from Apple and he's worried about the order. He ordered an AT&T model, but his wife moving to Verizon. Can he swap it through the Apple store? Leo says that's probable. He'll definitely want to do that since the phones are locked to the carrier. The Verizon model would work with AT&T, but not the other way around. That's because Verizon's phone is unlocked, but have different radios in each. Leo suggests not even opening the box. He should just take the phone to the Apple Store and swap it out.

Can I use a Verizon phone on T-Mobile?

Apple iPhone 4

Steve from Glendora, CA

Steve was gifted an iPhone 4 and the carrier is verizon, while his carrier is T-Mobile. Leo says Steve can't use it because the iPhone 4 is a CDMA phone while T-Mobile uses GSM. So it's essentially apples and oranges. It's just not compatible. The new iPhones though are "world phones" and can use various SIMs. Leo says that's where it's going, especially for Verizon because they were ordered by a judge to stop locking their phones to a carrier.
