3 Key Points When Choosing a Used Smartphone

While used smartphones offer attractive prices, choosing incorrectly can lead to immediate malfunctions or unsatisfactory performance. Here are three key points to avoid making a mistake.

Buy from a reliable seller

When purchasing a used smartphone, choose a seller with a strong sales record and high customer reviews.It is also important to check whether a warranty period is offered and if the condition of the device and whether it has been tested are clearly stated.Especially for online purchases, confirm the return and exchange conditions in advance.

Check battery performance and cosmetic rank

Since used smartphones have been used,it is essential to check for battery degradation, scratches, and dirt.

Some sellers display cosmetic ranks such as "A-rank" or "B-rank," and you may be able to check with photos. It is also essential to confirm whether the battery has been replaced and its maximum capacity.

Choose a model that suits your needs

Specifications and functions vary greatly depending on the model.If you perform demanding tasks such as gaming or video editing, a high-spec model is suitable, but if your main use is social media or calls, a mid-range to entry-level model is sufficient.

Also, check if features you use daily, such as mobile payment or water resistance, are included.

Checkpoints When Buying a Used Smartphone

To purchase a used smartphone with peace of mind, please check the following points.

• IMEI number and network usage restrictions

• SIM lock and SIM standard

• Is the battery level/condition clearly stated?

• Accessories and scratches/signs of use on the main unit

We will explain each point.

IMEI number and network usage restrictions

Before purchasing, check the IMEI number and make sure that the network usage restriction is "〇".If the usage restriction is "△" or "×", there is a risk that communication may become unavailable.

Even if you cannot check the IMEI number before purchasing, if the shop offers "network usage restriction guarantee" or "red ROM guarantee", you can purchase with peace of mind as you will be able to receive a replacement of an equivalent product or other support if a restriction is applied.

SIM lock and SIM standard

Always confirm SIM unlock status. If the SIM is locked,it can only be used with a specific carrier's network,which may prevent immediate use after purchase.

Also, it is essential to check if the SIM card you use matches the smartphone's SIM standard (nanoSIM, eSIM, etc.). Make sure your current SIM is compatible before purchasing.

Please refer to the following article for information on how to check and unlock SIM locks.

Is battery level/condition clearly stated?

Since used smartphones often have degraded batteries, when purchasing,make sure that the maximum battery capacity and condition are stated.

Ideally,choose a device with a battery condition of "80% or more" for peace of mind. Devices with a battery condition of less than 80% are more likely to experience symptoms such as the battery quickly draining within a day or slow charging speeds.

The following article explains more about battery level.

What is the battery level of a used smartphone? Also check the maximum capacity.

Accessories, scratches and signs of use on the main unit

The physical condition, such as whether there are noticeable scratches on the main unit and the condition of the LCD, is an important factor. Also,check if accessories such as chargers and earphones are included.

Carefully check the photos and product description, and choose a product with "actual images" to better understand its condition.

For websites where you cannot physically inspect the product, refer to the product rank.

"Unused" or "A-rank" products have minimal signs of use and are often like new smartphones.While the price may be higher, the peace of mind and satisfaction regarding quality will be greater, leading to less regret.

If you're buying a used smartphone, "PRODIG" is highly recommended!
