You want to get a great deal on a smartphone, but
"I'm worried about buying online" or "I'm concerned that a used item might be broken."
For those in their 20s and 30s facing such concerns, this article thoroughly explains the points and precautions for safely purchasing a smartphone online.
This content is a must-read, especially for those considering their first online purchase or a used smartphone. We will also introduce the features and support system of the reliable online store "PRODIG" to help turn your anxiety into confidence.
Pros and Cons of Buying a Smartphone Online

Pros: Cheaper and More Convenient
Online purchases often mean lower costs compared to physical stores, so you can often get the same model at a lower price. Additionally, you can purchase without time or location constraints, and attractive benefits like campaigns and point rewards are also appealing.
Cons: Uncertainty of Not Being Able to See the Actual Product
The biggest concern is buying without being able to touch the actual device. This is even more so for used items, leaving questions like "Does it work properly?" or "How good is the battery life?" To alleviate this anxiety, it's crucial to purchase from a trustworthy website.
Checklist for Safely Purchasing a Smartphone Online

Check for SSL/HTTPS
Since you'll be entering personal and credit card information during purchase, always check that the site's URL starts with "https://". Sites with a lock icon are encrypted and secure.
Check the Reliability of the Online Store
Other points to check include whether there is a physical store, if the operating company's address and contact information are clearly stated, and if there is a "Display based on the Act on Specified Commercial Transactions." PRODIG has a physical store in Akihabara, and clear company information is posted on its website.

Payment Method Security
It's more secure if you can choose from various payment methods besides credit cards, such as PayPay, Apple Pay, Google Pay, and deferred payment. Using PayPal or deferred payment allows you to pay after the product arrives.
Avoid Purchasing on Public Wi-Fi
Purchasing using free public Wi-Fi carries a risk of personal information leakage. If absolutely necessary, use a VPN app.
Precautions When Purchasing a Used Smartphone
Red ROM / Network Restriction
Red ROM refers to a state where communication is restricted, for example, if the previous owner failed to pay the device's cost. Before purchasing, confirm that the "network usage restriction is O (allowed)."
Check SIM Lock / Band / SIM Size
You need to check if it's compatible with your carrier. A SIM-free device can work with a wide range of mobile carriers.

Check Activation Lock
For iPhones, if the previous owner's Apple ID remains, you won't be able to use it. It's essential to check that it has been initialized and "Activation Lock is off."
Battery Condition / Exterior Rating
Used items may have degraded batteries. PRODIG clearly states operation checks, cleaning, and condition ratings, allowing you to choose with confidence.
