iPhone 8 Latest Trade-in Market Price and System in 2025

Although several years have passed since its release, the iPhone 8 still enjoys strong popularity and a steady demand in the used market. It is often used as a secondary device, for children, or for business purposes, and it is not uncommon for devices in good condition or with large storage capacity to be purchased at a solid price.

The purchase price varies greatly depending on the "storage capacity," "carrier (SIM-free or not)," and "condition of the device." Below is a summary of the market prices as of June 2025.

Reasons for Market Price Differences (Capacity, Condition, SIM Lock)

Differences in purchase prices are mainly determined by the following factors:

• Capacity difference: The 256GB model can fetch up to approximately ¥2,000 more than the 64GB model.

• Presence of carrier lock: SIM-free devices have a wider range of uses and higher popularity, so their purchase price tends to be higher.

• Device condition: Screen cracks, frame scratches, and battery degradation can lead to a reduction in value.

• Presence of accessories: Having original boxes, charging cables, and other accessories may result in a higher appraisal.

By understanding these elements and objectively assessing the condition of your device, you should be able to receive a satisfactory appraisal.

Specific Checkpoints for Selling at a High Price

Reliable Purchase Methods and Recommended Stores

There are three main ways to sell your iPhone 8: in-store trade-in, mail-in trade-in, and on-site trade-in. Each method has its own advantages and disadvantages, but for a hassle-free experience, it's important to choose a method that suits your lifestyle and a trustworthy provider. Here, we introduce representative trade-in methods and recommended providers.

Importance of Data Deletion Support and Initialization Assistance

The biggest concern when selling an iPhone is "data handling." If the device is not properly initialized, there is a risk of personal information leakage. Reputable buying services may explain the data deletion process or perform it on your behalf during the pre-purchase verification.

PRODIG carefully checks for activation lock and iCloud. Even first-time sellers can entrust their devices with peace of mind.

Process for a Smooth and Secure Trade-in

To confidently sell your iPhone 8, it's crucial to follow a few steps. Especially for first-time sellers, simply knowing what to prepare can alleviate anxiety.

How to Use Pre-Appraisal (LINE/Online Appraisal)

In recent years, many buying services offer "pre-appraisal services" via LINE or their websites. You can get an estimated purchase price by simply answering a few questions or sending photos.

By getting appraisals from multiple services and comparing prices, you can potentially get the highest appraisal. This is especially effective for busy individuals or those who want to know the market price before visiting a store.

Steps for complete data erasure (iCloud sign-out, Activation Lock deactivation)

Before selling your device, always perform the following operations:

1. Sign out from "Settings > Apple ID > iCloud"

2. Turn off "Find My iPhone"

3. Perform "Erase All Content and Settings"

This will deactivate the Activation Lock, allowing the next user to use the device smoothly. Be aware that devices with an active iCloud login may not be accepted for purchase.

Payment and Device Handover Process After Purchase

At PRODIG's Akihabara store, you can bring in your device, have its condition checked, and receive an appraisal value on the spot. If you agree to the appraisal, immediate cash payment will be made.

The process from drop-off to payment is very smooth, making it ideal for busy individuals.
