This article thoroughly explains the appeal of the iPhone SE 2nd generation SIM-free model, key points to check when buying used, its compatibility with low-cost SIMs, and its practical performance in daily use. We also introduce the benefits of purchasing from PRODIG for those who prioritize "peace of mind, affordability, and practicality" even with used smartphones.

The Appeal and Current Status of Used iPhone SE 2nd Generation SIM-Free

Market Price and Availability of Used SIM-Free SE2

In the used market, the iPhone SE 2nd generation is a very popular model, available from around 20,000 yen. Particularly, the 64GB model is often available for around 20,000 yen, and the 128GB model for under 30,000 yen, offering excellent cost performance.

There is also a relatively large supply of SIM-free models, and if you include carrier versions that have been SIM-unlocked, there are plenty of options. Although it was released in 2020, it still supports iOS 18, so there are no issues with daily use.

For those considering using it with a low-cost SIM or as a secondary device, it is a well-balanced choice with an affordable price and sufficient performance.

Differences Between Carrier and SIM-Free Versions (Unlock and "Red ROM" Risk)

iPhone SE 2nd generation devices sold by carriers may initially be SIM-locked. Many devices are now SIM-unlocked and resold as SIM-free, but verification is essential.

The main differences between SIM-free and carrier versions are as follows:

Carrier versions, in particular, carry the risk of "Red ROM." This occurs when the device's payment is outstanding, leading to network usage restrictions that can prevent communication.

Always check the network usage restriction status when purchasing.

Pre-Purchase Checklist for Used Devices (Peace of Mind)

How to Check for "Red ROM" / Usage Restrictions (Network Restriction Status)

You can easily check for "Red ROM" using a "Network Usage Restriction Checker." By entering the IMEI (serial number) for each carrier, you can check the status: ○ (clear), △ (pending), or × (restricted).

• ○: Payment complete, no restrictions

• △: Installment payments ongoing, no restrictions currently

• ×: Payment incomplete, communication restricted

Always check this status before purchasing a used device to avoid "Red ROM" risks. PRODIG clearly indicates network usage restrictions at the time of listing, so you can purchase with confidence.

Checking Activation Lock and Initialization Status

If the activation lock is not released, the previous owner's Apple ID will remain, making the device unusable. This occurs when the "Find My iPhone" feature is still on, and it also carries risks such as the device being stolen.

Before purchasing, always check:

• If the activation lock is released

• If the device has been completely initialized. All products at PRODIG are sold in an initialized and unlocked state, helping you avoid such issues.

Checking Battery Maximum Capacity and Degradation Criteria

The "maximum capacity" found in iPhone's "Settings > Battery > Battery Health" is a crucial check item when choosing a used device.

• 100%〜90%: Almost like new

• 89%〜80%: No issues for normal use

• 79% or less: Replacement recommended level

If the battery is degraded, it might not last a full day. PRODIG also clearly states the battery condition, which helps with purchase decisions.

Measures Against Malicious Apps and Remote Control Risks

Occasionally, used devices may still have malicious profiles or monitoring apps. To prevent this, it is desirable that the device has been reset to factory settings.

• Check for unfamiliar profiles in the Settings app

• Confirm that no profiles or VPN settings exist

At PRODIG, all devices are initialized to factory settings, with complete deletion of internal data and cleaning performed.

Savings with SIM-Free Operation

How Much Can You Save on Communication Costs with Low-Cost SIMs? Examples Included

One of the biggest advantages of using an iPhone SE 2nd generation SIM-free is the reduction in communication costs by combining it with a low-cost SIM. For example, while a carrier contract might cost 6,000 to 8,000 yen per month, you can operate with a low-cost SIM for as little as 1,000 to 2,000 yen per month.

【Comparison of Monthly Communication Costs】

As shown, there is potential to save tens of thousands of yen annually on communication costs, which is a significant benefit for cost-conscious users.

Cost Advantages for Sub-Devices or Dual-Phone Use

The iPhone SE 2nd generation is compact and lightweight, making it an ideal model for sub-devices or dual-phone use. It offers practicality in the following ways:

• Separate use as a work phone
  Separate business and private numbers for easier management.

• Communication device for travel/business trips
  Insert an international SIM and use it directly abroad. Also serves as a countermeasure against theft/loss.

• Simple smartphone for children or the elderly
  Simple basic operations make it excellent as a first smartphone.

With the device itself available from 20,000 yen, and maintenance costs kept low with a low-cost SIM, the cost of owning two devices is also reduced.

Practicality Check for Daily Use

OS Support and Future Usable Period

Despite being released in 2020, the iPhone SE 2nd generation currently supports the latest iOS 18 as of 2025. Apple typically provides 5-6 years of OS support, so it's safe to assume it will remain practical until at least 2026-2027.

Compatibility with iOS updates means that security and app compatibility remain up-to-date. This is a significant reassurance for those who want to use a device, even a used one, with peace of mind for a long time.

Performance Review for Practical Use: Camera, SNS, Videos, etc.

The iPhone SE 2nd generation is equipped with the A13 Bionic chip, equivalent to the iPhone 11, offering excellent processing performance. It handles daily tasks without issues:

• Daily apps like SNS, LINE, email: Smooth operation, no noticeable lag.

• Camera (12MP): Supports Portrait Mode and 4K video recording.

• Video streaming (YouTube, Netflix, etc.): Good visibility with the Retina display.

• Web browsing and online shopping: Fast page loading, comfortable experience.

While the display is a small 4.7 inches, it's actually convenient for those who prioritize ease of one-handed operation. If a large screen isn't a must-have, its performance and practicality are more than sufficient.
