How to buy a used iPhone 15 cheaply: A complete guide to getting one safely and affordably

"I want to get the latest iPhone 15 at a good price, but a new one is expensive and I'm a bit uneasy about used ones..."

For you, this article thoroughly explains how to safely and affordably purchase a used iPhone 15. We comprehensively cover carrier programs, previous-generation sales, reliable purchasing sources, checkpoints, and timing tips!

 


Summary of how to buy a used iPhone 15 cheaply

There are multiple ways to get a used iPhone 15 cheaply. Each option has different characteristics, such as cost, flexibility, and warranty availability. Before considering a purchase, it's important to know which method suits you best.

Carrier Certified / SIM-Free Combination Purchase / Previous-Generation Sales / Return Programs

Carrier-certified used devices offer peace of mind regarding warranty and maintenance, but their prices tend to be somewhat higher. On the other hand, purchasing with a low-cost SIM card can reduce monthly costs, making it practically more affordable to use. Also, immediately after the launch of a new iPhone model, the previous model, the iPhone 15, tends to drop in price as an older generation, so sales at this time should not be missed. In addition, return programs offered by carriers like docomo and au are another way to use an iPhone 15 at a lower cost, on the premise of returning it after a certain period of use.

Comparison of advantages and disadvantages of each method (cost, flexibility, usage restrictions, etc.)

Each method has its pros and cons. Carrier-certified used devices are reassuring but tend to be more expensive. SIM-free bundles can save on costs, but careful attention to communication quality is required. Aiming for an older model offers significant price advantages, but requires careful timing. Return programs allow for cheap usage, but the drawback is not being able to keep the device. Compare these and consider the option that best suits your usage style.


Recommended purchase sources and feature comparison

When purchasing a used iPhone 15, it is important to choose a trustworthy seller. By comparing prices, warranty availability, stock status, and the possibility of physical inspection, you can make a safe and affordable purchase.

Iosys / Nico Suma / Geo Online / Apple Certified Refurbished / PRODIG

Well-known purchasing sources each have their own characteristics. Iosys and Nico Suma have a wide range of inventory and prices, while Geo Online offers attractive benefits such as point rewards. Apple Certified Refurbished products offer high quality assurance and peace of mind, but prices are slightly higher. PRODIG handles products that have been tested for operation, cleaned, and come with a "red SIM" guarantee, and you can also inspect the actual product at their physical store in Akihabara.

Comparison of inventory volume, price range, warranty content, and transparency of battery status

The availability of warranties and the clarity of descriptions vary among retailers. PRODIG, in particular, clearly indicates the rank and condition, and you can check the battery status in advance. Additionally, the stable inventory volume is an advantage, as it means you won't miss out on a purchase opportunity.

Reliable Purchase Checkpoints

When purchasing a used iPhone, there are points you should check to alleviate any concerns. Here, we introduce typical risk avoidance measures and verification methods.

How to check for red ROM, network restrictions, and battery degradation

A "red ROM" refers to a smartphone with communication restrictions due to unpaid device fees. To avoid this, confirm that the "network usage restriction" is set to "○". Additionally, battery status can be checked by going to "Settings" → "Battery" → "Battery Health", and devices with a maximum capacity of less than 80% may require battery replacement. If the condition is not clearly stated on the sales website, it is advisable to refrain from purchasing.

Why rank notation, actual product photos, and operational warranty contribute to peace of mind when purchasing

The "rank notation" on a sales website is an important source of information for judging the condition of a product. It is safer to choose a store with clear standards, such as A-C ranks or "excellent condition/good condition/with defects." If actual product photos are provided, you can check the extent of scratches and dirt beforehand. Also, the presence or absence of an operational warranty needs to be confirmed to reduce the risk of potential malfunctions after purchase.


Timing and tips for smart shopping

In the used smartphone market, prices fluctuate and campaigns are held. By taking advantage of these, you can make even more advantageous purchases.

Times when prices tend to drop, such as immediately after a new product announcement, at the end of the fiscal year, or during bonus seasons

Immediately after Apple's new product announcements (around September each year), at the end of the fiscal year, and during bonus payment periods, prices in the used market tend to fall. Especially for recent models like the iPhone 15, a price drop is likely to occur with the release of a new model, so it is recommended to aim for purchases during such times.

Methods to reduce the actual burden, such as sales, campaigns, and point rewards

E-commerce sites periodically offer sales and campaigns. PRODIG also sometimes has sales, so it's a good idea to check their official website and social media. Additionally, combining credit card point rewards and cashless payment benefits can further reduce your actual expenses.
