How to Change Your Device to a Used iPhone Yourself!
If you're looking to get an iPhone at an affordable price, a used iPhone is a great option.
However, many people are anxious about questions like, "Can I switch to a used iPhone and use it?" or "Is it difficult to set up and transfer data myself?"
In reality, if you understand the necessary steps, you can smoothly switch without going to a carrier store.
This article will explain in detail the benefits of using a used iPhone, the specific steps for changing models, and important considerations.
We will also introduce methods for backing up and transferring data that are useful when changing models yourself, so please read to the end and learn how to smartly utilize a used iPhone.
How to use a used iPhone
First, let's look at how to effectively use a used iPhone.
Utilizing with a low-cost SIM
When you get a used iPhone, the most valuable way to use it is often by combining it with a low-cost SIM. You can acquire a device significantly cheaper than regular carrier lineups, and by using a low-cost SIM that reduces monthly fees, you can save on total communication costs.
Especially with a SIM-free used iPhone, the advantage is that you can choose any low-cost SIM provider you like.
However, if you purchase a used device that still has a SIM lock, you may need to unlock the SIM separately, so please check the device's condition before purchasing.
Use as a secondary device
You can also use a used iPhone as a secondary device, separate from your main smartphone.
For example, it's ideal if you want to separate your work and personal numbers, or if you want a dedicated device for social media or gaming.
Some iPhones also support dual SIM, so you might be able to operate two lines on one device.
Furthermore, a secondary device doesn't always need to be the latest model, and an older iPhone can still serve its purpose well.
Because used iPhones are available at an affordable price, they can be easily adopted as secondary devices.
Use only when connected to Wi-Fi
For those who have already switched smartphones but still want to use iPhone apps and features, using a used iPhone as a Wi-Fi-only device is another option.
Even without a cellular contract, you can access the internet, social media, music, and video apps as long as there's a Wi-Fi environment.
Reusing a used device is also useful for using an old iPhone as a tablet replacement or setting it up as a device for children.
How to change to a used iPhone
Here's how to change to a used iPhone yourself.
The basic steps are similar whether you're migrating from iPhone to iPhone or from Android to iPhone, so please refer to these instructions.
Purchase a used iPhone
First, acquire a used iPhone. You can purchase one at used sections of electronics retailers, online stores, specialty shops, or auction sites.
Here are the points to check:
- SIM lock status (whether it's SIM-free)
- Risk of "red ROM" (whether usage is restricted)
- Battery degradation status
- Scratches or damage to the exterior or screen
To use it with peace of mind, it's recommended to choose a shop that offers a warranty or a return policy for a certain period.
Back up data from your old smartphone
Before changing models, be sure to back up your old smartphone's data.
You can back up the entire iPhone using iCloud or iTunes (PC), or perform manual backups for individual apps.
If you're migrating from Android to iPhone, the common method is to save photos and contacts to the cloud using Google services and then re-download them to the new iPhone.
Replace the SIM card
Transfer the SIM card from your old smartphone to the used iPhone while both are powered off. If the SIM card size (nano, micro, standard) doesn't match, you'll need to go to a carrier store or low-cost SIM service to change the size. Once you insert the SIM card into the used iPhone and turn it on, it should be able to communicate if recognized correctly.
Perform initial setup
After starting up your used iPhone, perform the initial setup including language settings, Wi-Fi settings, and Apple ID login. Connecting to Wi-Fi first is convenient, as it allows for smooth OS updates and app installations. Registering Touch ID or Face ID at this stage will also enhance convenience later on.
Migrate backup data
Next, we will explain the steps for migrating backup data.
Please note that the procedure varies depending on whether you're migrating from iPhone to iPhone, or from Android to iPhone, and other combinations.
When migrating from iPhone to iPhone
[Using iCloud backup]
- On your old iPhone, go to "Settings" → "Apple ID" → "iCloud" → "iCloud Backup", enable it, and tap "Back Up Now" to back up the latest data.
- During the initial setup of your new iPhone, select "Restore from iCloud Backup" and log in with your Apple ID.
- Backup data will be automatically downloaded, and apps, photos, and settings will be restored.
[Using iTunes (PC) backup]
- Connect your old iPhone to your PC and back it up with iTunes (encrypting it also protects passwords and health data).
- Connect your new iPhone to the same PC and transfer the old iPhone's data by selecting "Restore Backup".
When migrating from Android to Android
[Utilizing Google Account]
- On your old device, go to "Settings" → "Accounts" → "Google," enable synchronization, and back up contacts and photos to Google Drive/Google Photos.
- Log in to the same Google account on your new device, enable synchronization, and data will be automatically restored.
When migrating from iPhone to Android
When migrating from iPhone to Android, the method varies depending on the type of data.
For photos, it's convenient to use cloud services like iCloud or Google Photos.
Contacts can be migrated by exporting them from iCloud in vCard format and then importing them into Android.
Additionally, for apps, you need to check if an Android version exists and download them individually.
When migrating from Android to iPhone
[Using the "Move to iOS" app]
- Install the "Move to iOS" app on your Android device.
- During the initial setup of your new iPhone, select "Migrate from Android" on the "Data Migration" screen.
- Enter the displayed code on your Android device to start data migration.
Check the operation after setup is complete
After completing all data migration and initial setup, perform a series of operational checks, including calls, internet communication, camera, and app launches.
If it works without problems, the model change to a used iPhone is complete.
If there are any issues such as the SIM not being recognized or communication not being possible, recheck the APN settings and SIM unlock status.
Points to note when purchasing a used iPhone
While used iPhones are cheaper than new ones, there are some risks and points to be aware of.
Here, we have summarized the items you should check before purchasing.
Check the physical condition
Damage such as a cracked screen, scratches on the frame, or cracks in the back glass can later affect its operation or appearance.
When purchasing, carefully check product photos or the actual item to ensure there are no major external issues.
Check memory capacity
iPhone storage capacity is fixed and cannot be expanded later.
Models with small capacities like 16GB or 32GB are highly likely to run out of storage quickly if you store many photos and apps.
You can use it comfortably if you choose 64GB or more, depending on your usage.
Check the IMEI number
It is important to check the IMEI number (a unique identification number for the device) and verify on the carrier's website whether network usage restrictions are imposed.
If there is an outstanding balance, there is a risk of communication being blocked, resulting in a "red SIM" status.
It would be counterproductive if you can't use the device after purchasing it, so be sure to check in advance.
Perform a water damage check
iPhones have an internal water damage indicator, and if it turns red, it indicates water damage.
Since it's not possible to tell from the exterior alone, it's safer to have it checked at a shop or confirm that it's clearly explained.
Check network usage restrictions
As mentioned above, if the IMEI number is marked with "△" or "×", it is likely under restriction or may become restricted.
Before purchasing, enter the IMEI on the carrier's website and check if it is marked with "○".
Check Activation Lock
An iPhone with Activation Lock (locked by Apple ID) cannot be unlocked without the previous owner's Apple ID password.
When purchasing from a used shop or individual, always confirm that "Activation Lock has been disabled".
Check warranty details and period
Some shops offer their own warranties even for used items.
It's reassuring to understand the warranty period and coverage, such as whether they will handle initial defects or delivery issues, before making a purchase.
Advantages of using a used iPhone
A used iPhone is cheaper than a new one.
If you don't insist on a brand new device, owning a used iPhone offers various benefits.
Here, let's organize the advantages unique to used items.
Advantage ① Low purchase price
You can get them at half the price of the latest models, or sometimes even for 10,000 yen, significantly reducing initial costs.
Even for high-end models, if they are one or two generations old, they can offer excellent value for money.
Advantage ② Easy to purchase the device only
The flexibility of purchasing only the device online or from a used shop, without going through a carrier store, and inserting your preferred SIM is a major plus.
Switching to a low-cost SIM can also reduce communication fees.
Advantage ③ High resale value
iPhones are highly popular in the used market and tend to be bought at relatively high prices.
Compared to Android, their resale value is higher, which can potentially reduce your expenses when upgrading to a new phone.
Advantage ④ Good compatibility with low-cost SIMs
If you have an unlocked used iPhone, it has high compatibility with various low-cost SIMs, allowing you to keep your monthly communication fees low.
Additionally, the setup process is clear and user-friendly, making it safe even for first-time users.
Advantage ⑤ You can purchase after checking reviews and reputations of the model
Since a certain period has passed since its release, there are plenty of real-world usage experiences and reviews available.
Being able to grasp issues and battery life beforehand is an advantage unique to used products.
Disadvantages of using a used iPhone
Of course, there are risks and disadvantages unique to used items. By fully understanding them before purchase, you can prevent problems.
Disadvantage ① Possibility of "red SIM" status
If the previous owner failed to pay for the device or if it was a stolen device, it will be restricted by the carrier (red SIM).
There is a risk that communication will be stopped after purchase, so checking the IMEI number is essential.
Disadvantage ② Accessories may not be included
Often, devices are sold without the box, earphones, or charging cable.
You may incur additional time and cost to purchase necessary accessories separately.
Disadvantage ③ Battery may be degraded
With used iPhones, the battery may be degraded depending on the previous owner's usage.
If the maximum battery capacity is less than 80%, problems such as sudden shutdowns are more likely to occur. Check the battery condition as much as possible before purchasing.
[Finally] Enjoy a fulfilling smartphone life with a used iPhone
Switching to a used iPhone is not difficult if you understand the process yourself.
If you properly replace the SIM card and perform a backup and data migration, you can switch without visiting a carrier store.
However, you need to be aware of the disadvantages unique to used phones, such as the risk of "red ROM" (blacklisted phones) and battery degradation.
Even so, the benefits are significant, and the appeal of a used iPhone lies in its ability to make smart smartphone choices due to its excellent cost-performance and high resale value.
Especially because iPhones often receive long-term iOS updates even for older models, they maintain strong popularity in the used market.
