Worried about buying a used smartphone online? Checkpoints for a successful purchase and recommended sites

Used smartphones offer excellent cost performance, and if chosen wisely, you can acquire high-performance models at a great price. However, many questions and concerns arise, such as "I'm a bit uneasy about buying online," "What is a 'red-locked' phone?", or "What if it's broken?"

This article will address common concerns and risks associated with buying used smartphones online, provide checkpoints to avoid them, and explain how to identify reliable online stores. Furthermore, in the latter half, we will introduce the reassuring aspects of "PRODIG," a used smartphone specialty store with a physical location in Akihabara.

Common Concerns and Issues with Used Smartphones Purchased Online

Red-locked Phone Risks and IMEI Check

A "red-locked" phone is a device with communication restrictions imposed by the carrier, often because the previous owner defaulted on installment payments. Before purchasing, check the IMEI number and verify the network usage restrictions on each carrier's official website.

Difficulty in Assessing Battery and Internal Condition

Even if a device looks clean externally, the battery, motherboard, or other internal components may have deteriorated. It is crucial to check if the battery capacity (e.g., 80% or higher) is clearly stated on the product page.

Risks of Water Damage, Repair History, and Malicious Apps

With unofficial sellers or peer-to-peer transactions, it can be difficult to detect water damage or motherboard issues. Check if the device has been tested for functionality, factory reset, and if a clear inspection process is documented.

Remaining SIM Lock and Activation Lock

iPhones with an unresolved SIM lock or a remaining Apple ID (Activation Lock) may be unusable. Always confirm that "unlocked" is explicitly stated.

Risks of No Warranty or No Returns

Flea market apps and auctions often offer no post-purchase warranty. A lack of support in case of a "red-locked" device or initial defects can lead to regret.

Checklist for Safely Purchasing Used Smartphones

【Key Check Items】

• Disclosure of IMEI number and presence of red-locked phone warranty

• Numerical display of battery health (80% or higher)

• Indication of Activation Lock being released

• Presence of return policy and initial warranty
