The Growing Interest in Refurbished, Used, and Carrier-Locked iPhones: Saving Significantly with Comparable Quality to New Devices
Beyond the Cost Advantage: Understanding the Potential Risks of Refurbished iPhones to Make an Informed Purchase Decision
What is a Brand New iPhone?
This term refers to iPhones that are 100% new, with the original device and outer box seals intact. The device has no scratches or external damage, and the battery charge cycle count is zero.

Brand new iPhones come in two types: official VN/A products and imported units. VN/A models, being directly from the manufacturer and officially warranted in Vietnam, are the most sought-after and expensive among iPhone options due to their authenticity.
The second type consists of imported devices. These are rare, mainly appearing shortly after product launches but declining over time due to their less competitive prices compared to other imported goods.
What Defines a Refurbished iPhone?
Refurbished, also known as factory restored or reconditioned, refers to products returned to the manufacturer for reasons like hardware defects during production. These are thoroughly inspected, repaired, and repackaged before being resold. In Vietnam, refurbished smartphones are most commonly associated with Apple iPhones.

Refurbished smartphones, notably superior to returned or used items, offer more reliability. Unlike purchasing used devices from shops or individuals, where internal hardware tampering is a risk, refurbished smartphones are sold with original seals and official accessories.
Origin and Warranty Policies
For refurbished phone purchases, prioritize reputable stores. Pay attention to whether the device is manufacturer-refurbished or store-refurbished and whether it includes an official manufacturer's warranty or only a store-provided warranty.

Apple still offers official global warranties for its Refurbished iPhones. Therefore, when buying a refurbished iPhone, ensure the device and its IMEI number match, haven't been activated, and are still eligible for warranty via Apple's system at https://checkcoverage.apple.com/ or in the device's 'About' section.
Distinguishing Between Refurbished and Brand New iPhones
In Vietnam, official iPhone distributors do not sell refurbished devices. Globally, only a few carriers like AT&T, O2, and Orange offer such products, which enter the Vietnamese market unofficially, either through personal imports or from China.

Most Vietnamese stores do not disclose the refurbished status of these products to customers, often marketing them as new to sell at higher prices. Therefore, buyers should thoroughly check the IMEI and warranty period on Apple's official website.
What is a Carrier-Locked iPhone?
Carrier-Locked iPhones, also known as network-locked iPhones, are devices that can only operate with a SIM card from a specific carrier due to a usage contract. To use a different mobile network, users must unlock the phone with a code or use a SIM adapter. These iPhones are often cheaper than international versions because they are subsidized by the carrier.

There are two main methods to unlock a Carrier-Locked iPhone: The first involves unlocking it to use internationally, which can be costly and not supported by all carriers. Therefore, it's important to know how to check if an iPhone is carrier-locked for safety.

The second method involves using a SIM adapter, preferred for its quick and inexpensive solution. For about 100,000 to 200,000 VND, you can buy a SIM adapter to unlock the phone for normal calls. However, this method can be unstable and may introduce errors, requiring users to know how to properly use the SIM adapter.
What Are Used iPhones?
Used iPhones, often in 99% new condition, show minimal wear, may have gone through few charging cycles, and most importantly, are sold at a significantly lower price than brand-new, sealed official units.

Choosing wisely when buying this type of device can lead to considerable savings, freeing up budget for other expenses.
Used iPhones can be either carrier-locked or international versions, so buyers need knowledge to select the best devices. Especially with used purchases, it's crucial to choose reputable sellers offering warranties and good after-sales service.
iPhones with Certain Malfunctions (missing FaceID, TouchID, etc.)
These are the cheapest but also the riskiest types of iPhones available, and it's generally best to avoid purchasing them.

Face ID and Touch ID are biometric security technologies using iris and fingerprint scanning for facial recognition and fingerprint unlocking on iPhones. Each iPhone is equipped with only one Face ID or Touch ID sensor, making it difficult to replace or repair if damaged.

Loss of Face ID or Touch ID functionality can result from water damage or physical impacts. Apple designs the Face ID sensor with the front camera assembly, light sensor, and proximity sensor, so damage to any of these components can result in Face ID failure.
The quality of iPhones with malfunctioning Face ID or Touch ID is unpredictable, as other components may also be affected. It's advisable to avoid these devices unless experienced in testing and evaluating their condition.
