It's common to replace your smartphone periodically. Do you have a smartphone lying around your house that you'd like to trade in or sell, but are worried because you're storing it at home without using it, you don't know where to get the best deal, or the process is too complicated?
In this article, we'll explain the difference between trading in and selling your smartphone, as well as what to keep in mind when applying for a trade-in. We'll also introduce a convenient and economical way to sell your smartphone and exchange it for gigabytes, so if you're struggling to find a use for your unused smartphone, be sure to check it out.

With the release of new smartphone models, the value of older models can decrease. That's why you'll want to trade in or sell the smartphone you have lying around your house as soon as possible.
To find out how best to use your smartphone, let's first clarify the difference between trading it in and buying it.
Smartphone trade-in basically refers to a service that allows you to receive a discount on the purchase price on the condition that you purchase a new model. Recently, trade-in services are being offered not only by major smartphone carriers, but also by various stores such as electronics retailers.
Trade-ins are suitable for the following people:
・ I'm planning to buy a new model
・ I want to keep the cost of purchasing a smartphone low.
・ I always buy my smartphone from the same store
The basic condition for trading in a smartphone is that you "purchase a new model," so if you meet this condition, you should first consider a trade-in service.
Recently, there are trade-in services that not only offer discounts on the purchase price of a smartphone, but also exchange it for points that can be used for various shopping purposes.
Smartphone buyback literally means "a service that buys back your smartphone." Unlike trade-ins, the purchase of a new model is not a condition of use.
The following people are suitable for purchasing:
I have no plans to purchase a new model
・ I want to make effective use of the smartphone lying around my house
However, when deciding where to sell your smartphone, you may be wondering where you can get the best deal.

Here, we will answer the question, "Where can I trade in or buy my smartphone?" Whether you can trade in or buy your smartphone will depend on the condition of your current smartphone and whether you plan to purchase a new model.
According to a survey by MM Research Institute, people have different ways of using their unused smartphones, but first let's organize the places where you can trade them in and buy them.
(Reference): Status of the smartphone you used previously

For iPhones, you can trade in your smartphone at the official Apple Store (official website) or your carrier. For Android phones, some manufacturers offer trade-ins on their official websites, but you'll generally need to use the trade-in service offered by your carrier.
When trading in your iPhone, the benefits vary depending on whether you trade in at an official Apple store or with a carrier.
The advantage of trading in your iPhone at an official Apple Store is that you may be able to purchase a new model at a lower price.
This is because the selling price of the iPhone is generally lowest at the official Apple Store.
■ Comparison of iPhone sales prices at the official Apple Store and major carriers
| Sales price (tax included) | Discount measures, etc. | |
|---|---|---|
| Apple Official Store | 149,800円 | none |
| au | 175,860円 | 22,000 yen discount for new contracts and switching from other companies |
| SoftBank | 175,860円 | 31,680 yen discount for new contracts for those aged 5 to 22 |
| docomo | 174,130円 | 2% d points awarded |
*All prices are for the iPhone 14 Pro 128GB (information as of April 2023)
As such, the standard selling price of an iPhone is lowest at the official Apple Store, so if you trade in your current iPhone, you may be able to purchase a new model at a lower price.
However, the official Apple Store does not accept trade-ins for the iPhone 6 series or iPhone SE (first generation).
The benefits of trading in your smartphone with each carrier, including major ones, include the fact that it is compatible with a wide range of models and that you can feel secure because it is a service provided by a major carrier.
The trade-in service at the official Apple Store only supports iPhones, and is only available for iPhone 7 and later models. On the other hand, the smartphone trade-in services offered by various carriers are only available for iPhone 6 and later models, and Android devices are also eligible for trade-in.
If you want to trade in an iPhone 6 series, iPhone SE (first generation), or Android, it's a good idea to use one of the carriers.
The places where you can buy your smartphone are mainly second-hand shops with second-hand goods licenses. Recently, Geo, Iosys, and Tsutaya have started offering trade-in services. Let's check the differences between them and telecommunications companies that offer trade-in services.
The advantage of second-hand shops such as GEO and Iosys is that you can sell your smartphone without having to buy a new model.
If you don't plan on buying a new smartphone or would like to make use of your old smartphone, we recommend using a smartphone buyback service.
The advantage of using the purchase service of a used smartphone shop is that popular models may be appraised at a high price.
The trade-in prices at official Apple stores and trade-in services provided by various carriers are determined by the model's release date. On the other hand, the buy-back services offered by second-hand smartphone shops are determined by the model's popularity, so depending on the model, you may be able to get a higher price than the market rate.

There are three things to keep in mind when trading in your current smartphone for a service that can convert it into a "discount on the purchase price" or "points." Researching trade-in benefits can be difficult, so it's important to check in advance whether you can apply for a trade-in.
The smartphone trade-in service requires you to upgrade your model (purchase a new model).
Therefore, you cannot "keep the smartphone you are currently using and trade in your old smartphone to receive points." If you are not planning on purchasing a new smartphone right away, consider applying for a buyback service.
The perks offered by smartphone trade-in services vary depending on the provider, so deciding where to trade in your phone can be a difficult task. Which perks are the best deal varies from person to person, so we recommend that you decide based on the perks you value most and the things that you find attractive.
The main trade-in benefits are as follows:
● Discount on the purchase price of a new model
● Point program and exchange
● Exchange for gift cards
The same trade-in store may have multiple offers, and the appraisal criteria for the smartphone you trade in may differ depending on the offer. Therefore, researching trade-in offers can take time.
For those who are busy with work, housework, childcare, etc., it would be nice to have an online trade-in service. However, some trade-in services only accept trade-ins in-store, so it's important to check whether the process is available online.
