How to Buy an iPhone 14 Cheaply | How to Get the Latest Model Used, Safely and Cost-Effectively

公開日: 2025年06月20日更新日: 2025年06月27日

For readers who want to get an iPhone 14 as cheaply as possible but find the latest model too expensive, or who are concerned about the condition of used items, this article explains how to make a smart purchase using four methods: carrier campaigns, refurbished products, used items, and trade-ins.

Four ways to get an iPhone 14 cheaply

Utilize carrier transfer and trade-in campaigns

Major carriers and MVNOs regularly offer significant discounts on devices, including the iPhone 14. Particularly noteworthy are measures to reduce the effective cost, conditioned on MNP (transferring with your existing number) or device returns. For example, Rakuten Mobile has offered up to 36,000 yen in cashback, and Y!mobile and ahamo also periodically offer devices at fire-sale prices.

These campaigns are usually bundled with a communication contract and may come with conditions such as continued use for a certain period, but they are an advantageous option when considering the total monthly cost.

Choose certified refurbished or reconditioned products

Apple Certified Refurbished products and reconditioned products from places like Back Market are characterized by their near-new quality and a price that is about 20-30% cheaper. Even relatively new models like the iPhone 14 are regularly available in the refurbished market and can be purchased with peace of mind as they come with a warranty.

As Apple's official refurbished products often run out of stock, it's wise to also check external vendors such as Back Market and Amazon Renewed.

Utilize the used market to aim for the lowest price

The price range for iPhone 14 in the used smartphone market varies depending on its condition, but generally, a 64GB model can be purchased from around 50,000 yen. Specialty stores like PRODIG, Iosys, Nicosma, and Musby clearly indicate the condition rank and battery health, and usually include a red-ROM guarantee.

By filtering with keywords like "unused item (S rank)" or "B rank beautiful item," you can select a reliable device with good cost performance. Since warranty periods may differ depending on the retailer, it is important to compare warranty conditions at the time of purchase.

Reduce net cost with a combination of used and trade-in

By trading in your current smartphone, you can effectively lower the purchase cost of an iPhone 14. PRODIG, in particular, offers clear trade-in prices and supports both online and in-store assessments. If you use the trade-in amount directly towards the purchase of a new device, you can change models while keeping your budget in check.

For example, by trading in an iPhone SE 2nd generation for 15,000 yen, you could potentially get an iPhone 14 for as low as 40,000 yen.

If buying used, check these points! How to choose with confidence

Maximum battery capacity

Battery degradation is a major factor when considering a used purchase. On an iPhone, you can check "Maximum Capacity" under [Settings] → [Battery] → [Battery Health]. A guideline of 80% or more is generally recommended, as anything below that will significantly reduce noticeable battery life. PRODIG clearly states the maximum capacity on its product pages, allowing you to check thoroughly before purchasing.

Presence of Red ROM Guarantee

"Red ROM" refers to a state where communication restrictions are placed on a device because its previous owner defaulted on installment payments. To prevent this, it is essential to purchase from a store that offers a "permanent Red ROM guarantee." PRODIG offers a Red ROM guarantee on all products, so you can rest assured in the event of any issues.

Distinguishing between SIM-free and carrier versions

A SIM-free iPhone 14 offers flexibility for use with MVNOs or overseas. While "SIM unlocked" used devices are safe, purchasing an un-unlocked carrier version will limit your freedom, so caution is advised. PRODIG clearly states the SIM status in its product titles and descriptions.

Operational check and cleaning indicated

When buying a used smartphone, it's important whether basic operational checks (camera, audio, Wi-Fi, Bluetooth, Face ID, etc.) have been performed. Furthermore, an indication that the exterior has been cleaned greatly impacts satisfaction upon arrival. PRODIG thoroughly inspects and cleans all products with specialized staff.

Benefits of buying from PRODIG and a secure purchase experience

PRODIG provides clear product information and comprehensive support for used smartphones, including the iPhone 14.

All products come with a Red ROM guarantee, operational check, and exterior cleaning.
Battery capacity and device condition are clearly stated.
Multiple product photos are provided to allow you to assess the condition before purchase.

Additionally, with a physical store in Akihabara, you can inspect the actual device or consult with staff directly before making an online purchase. This creates a reassuring environment, especially for those new to buying used smartphones.

Techniques for reducing replacement costs! Using trade-ins

To purchase an iPhone 14 cheaply, it's crucial to sell your current device smartly. PRODIG supports both online and in-store appraisals in Akihabara, and by keeping the following techniques in mind, you can aim for a high appraisal value.

Include original box, cables, and other accessories.
Complete initialization and iCloud deactivation.
Clean the exterior before requesting an appraisal.

Also, prices of older models tend to drop just before the release of new models (e.g., before Apple's new product announcement in September), so selling before then is the best timing.
