If you've shopped for a new smartphone over the last few years, or if you've tried to switch wireless carriers, you might have heard about unlocked phones. But what are unlocked phones, and what should you know about them before buying your next device?

"We are quite interested in looking at China's efforts and experience in combating corruption. It's a problem we are faced with in South Africa, and one we are tackling with a lot of vigor.Recently, the South African government introduced new measures to combat corruption. This is interesting, because it was immediately after a visit by our minister for public services, who met with the minister here who is responsible for anti-corruption measures.So this is one of the examples of the usefulness of this interaction between our leadership and the leadership of the People's Republic of China."

Despite the fact that each market rebound ended up as a V-shaped affair, each successive rally was carried out with less and less individual stock participation. Glaring divergences between winners and losers, large caps and small caps, preoccupied the commentariat for most of the spring and summer. Deflationary concerns from Europe and the Japanese technical recession further confounded analysts, as Treasury yields and inflation indicators in the U.S. were driven lower despite the improving domestic economy.

You should also find out if the carrier restricts any features to appear on only those phones they sell. Sometimes, carrier-locked devices get exclusive perks. AT&T, for instance, offers the option for voice-over-LTE and Wi-Fi calling only on handsets sold in the company's stores, not on unlocked phones. Say you brought a factory-unlocked Galaxy S10 Plus purchased separately to AT&T's network; even though AT&T offers the S10 Plus at the company's retail locations and on its website, you'll miss out on the special features, because you didn't buy the AT&T-specific model.

Who should buy an unlocked phone?

Early adopters. If you need to have the newest device as soon as it's released, then buying an unlocked phone is the way to go. You'll need to have the cash on hand to pay for the device up front, and you won't be able to take advantage of any carrier deals. But that's the price of having the latest and greatest tech before everyone else (5G phones notwithstanding, but more on that below).

Bargain hunters. From Alcatel to ZTE, several phone makers offer unlocked phones at very low prices. In fact, we've tested a number of 商业配套改建成酒店公寓 南京当代万国府ΜΟΜΛ涉嫌违规. One reason these phones are so affordable is that the manufacturers don't need to deal with carriers, and they can pass those savings on to you.

Frequent updaters. Buying an unlocked phone means you're free to upgrade when something new comes along. Even better, when you already own your current phone free and clear, you can resell it.

International travelers. Having an unlocked phone makes it easier to swap out your carrier's SIM card with a pay-as-you-go option for use on networks overseas.

Who should buy a phone from a carrier?

People who want to pay off a phone in installments. If you're looking for a deal on a brand-new flagship phone from Apple, Samsung, Google or any of the other major hardware manufacturers, your best bet is to go through a carrier. AT&T, T-Mobile, Sprint and Verizon all offer discounts, trade-in offers and other ways to entice you to buy a new phone (and sign up for monthly data plans). And if you decide you need your device unlocked later on, that's always your prerogative, so long as you meet the carrier's terms and conditions.

People who want to keep it simple. If you don't want the hassle of figuring out how to get your new phone up and running, going through a carrier is the wiser choice. You can get assistance with moving your SIM card over from your carrier (unless you purchase your new phone online), and many carriers will help you transfer your old phone's data over to your new phone.

5G early adopters. 5G devices are the lone exception to the general rule that early adopters should buy unlocked. These phones are still carrier-specific and likely will be for a while. So if you want superfast data speeds, you'll have to continue buying your device through a carrier for the foreseeable future. 

What should I do after I buy a phone?

Transfer your data. Most phones make it easy to transfer your old data, so you don't really need any extra help. For iPhones, all you need to do is sign in with your Apple ID to port over most of your contacts, apps and saved pictures. And for Android devices, you just log in to your Google account. You likely won't find it much of a hassle to switch data from your old handset if you go the unlocked route.

Delete some apps. You'll spend less time deleting unwanted apps and skins off an unlocked phone. Take an Android phone from Verizon, for example: It has a host of mostly redundant preinstalled apps, ranging from Verizon-branded apps and games to NFL Mobile and Slacker Radio. AT&T, Sprint and T-Mobile are bloatware offenders, too. (Good news if you prefer iPhones: Apple doesn't allow outside apps to come preinstalled on its phones.)

Still, even unlocked phones may feature some bloatware. An unlocked Galaxy Note 10 from Samsung comes with stuff you might not want, like the Samsung Gallery photo app and Samsung's Smart Home management app.

Buy insurance. You don't need to insure your smartphone, but if you've been known to shatter a screen or two, getting insurance is probably a good idea. When buying a phone through your carrier, you'll often get the option to add device insurance for a small monthly fee.
