After purchase, battery capacity may be less than 80% when the product is delivered to you. (This is not covered by the Free Warranty) - The exterior of these handsets is inspected and then cleaned by specialists.

- If the serial number (IMEI) at the time of purchase and the serial number of the handset sent to us do not match, or the serial number of the handset sent cannot be identified, it will not be eligible for the Free Warranty.
- If a malfunction is confirmed, we will replace it with a handset of identical model, capacity, and color (replacement will be with another handset handled by SoftBank as a certified used product, not with a new item).
*Note that if this is difficult due to inventory shortages, etc., we will replace it with another model that we specify, or we will refund your money after the device is returned to us. - We cannot guarantee app usage fees or charges, even if they are due to malfunctions. Additionally, loss of data within the handset is also not eligible for warranty, so please back up your data regularly.

- Damage due to customer modifications or processing (including when performed on the product body or on the software)
- Damage attributable to natural disasters after purchase

- Handsets offered as SoftBank certified used products may not be equipped with the latest OS version in some cases. Please upgrade to the latest OS version yourself. Additionally, preset applications may have been deleted.
- Handsets offered as SoftBank certified used products are eligible for Apple Authorized Support. However, since we do not dissemble products for inspection, there may be cases where Apple Authorized Support cannot be provided because the previous owner has used non-genuine parts. We are not able to accept returns or provide replacements in such cases. Your understanding is appreciated.
- If you forget an Apple Account password that you have set yourself, you may not be able to make inquiries with Apple Support, and you may not be able to deactivate the activation lock.
