The Rise in Popularity of Refurbished, Used, and Carrier-Locked iPhones for Cost Savings and Quality Comparable to New
Weighing the Benefits and Risks: A Guide to Choosing the Right iPhone in Today's Market
Defining a Brand New iPhone
A Brand New iPhone is one that's 100% new, with original seals on the device and box untouched by anyone but the purchaser, featuring no scratches or external wear and a battery that's never been charged.

There are two main types of Brand New iPhones: the VN/A official products directly from the manufacturer, the premium and most authentic option with an official warranty in Vietnam, and the imported units, which are generally less expensive.
The imported units are less common, typically available right after new product launches and become scarcer over time due to their less attractive prices compared to other imported options.
What is a Refurbished iPhone?
Refurbished, also known as factory restored or reconditioned, are products returned to the manufacturer for various reasons, such as manufacturing defects. These are inspected, repaired, and repackaged before being resold. In Vietnam, Apple's iPhones are the most common refurbished smartphones.

Refurbished smartphones generally offer better quality than returned or used items. Buying used devices can leave you uncertain about internal tampering. However, refurbished smartphones are sold with original seals and official accessories from the manufacturer.
Origin and Warranty Policy for Refurbished Phones
When purchasing refurbished phones, prioritize buying from reputable shops. Pay attention to whether the device is officially refurbished by the manufacturer or by the store, and verify the type of warranty provided.

Refurbished iPhones are eligible for Apple's official global warranty. Thus, when buying a refurbished iPhone, ensure to check the device and IMEI number for activation status and warranty validity on Apple's website or in the device's 'About' section.
Differentiating Refurbished and Brand New iPhones
Currently, official iPhone distributors in Vietnam do not sell refurbished devices. Internationally, carriers like AT&T, O2, and Orange offer them, entering the Vietnamese market unofficially through imports or from China.

Most stores in Vietnam do not clearly inform customers about the refurbished status of these products, often presenting them as new to sell at higher prices. Therefore, buyers should carefully check the IMEI and warranty period on Apple's official website.
What Does Carrier-Locked iPhone Mean?
What Are Carrier-Locked iPhones?

Carrier-Locked iPhones are restricted to a single network carrier due to a usage contract, requiring an unlock code or a SIM adapter for use with other networks. These iPhones are typically less expensive than international models due to carrier subsidies.

One method to unlock these devices involves a SIM adapter, favored for its quick and low-cost solution. With an approximate cost of 100,000 to 200,000 VND, a SIM adapter allows normal phone functions. However, this method is often unstable and can lead to various issues, necessitating proper knowledge for effective use.
Understanding Used iPhones
Used iPhones, at 99% condition, exhibit minimal scratches, may have fewer charge cycles, and importantly, are priced significantly lower than new, sealed official models.

Making the right choice in purchasing these devices can lead to substantial savings, allowing for allocation of funds to other expenditures.

iPhones with Functional Issues (Missing FaceID, TouchID, etc.)
These are the most affordable yet highest-risk devices among used iPhones, best avoided due to potential complications.

Overview of Face ID and Touch ID Biometric Security Technologies

Loss of Face ID or Touch ID can be due to water damage or physical impacts. Apple's integration of Face ID with the front camera and sensor array means damage to any can impair Face ID functionality.
The quality of iPhones with damaged Face ID or Touch ID is unpredictable, as other components might also be compromised. It's advisable to avoid these unless experienced in device assessment.
