Due to its lower price compared to other versions, iPhone Lock is gaining increasing attention. However, few truly understand what iPhone Lock is. How to easily check iPhone Lock and whether you should buy it. Follow this article to learn more about this issue!
1. What is iPhone Lock?
iPhone Lock is an Apple phone sold with an exclusive contract with a carrier. Therefore, iPhone Lock can only use the SIM of a specific carrier. When inserting a SIM from another carrier, the phone cannot be used. However, using a locked iPhone from abroad may encounter some issues such as weak signals, battery drain, overheating, faulty contacts, messages, inability to use mobile data, difficult software updates, etc. On the other hand, locked iPhone models are significantly cheaper than genuine or international iPhone models.

2. Easy Ways to Check iPhone Lock
To identify whether the phone you're using or planning to purchase is an iPhone Lock, you can apply the following checking methods:
2.1 Checking with the Camera
This is a method to check for iPhone lock applied by the Korean or Japanese market for export. In these countries, they respect the privacy rights of individuals and discourage the use of cameras for spying. Therefore, even if you have muted the volume button located in the top left corner, the camera sound remains on. So, to quickly check for an iPhone lock, you can try turning off the volume button and taking a picture.
2.2 Inserting a different carrier SIM card into iPhone
To understand what iPhone Lock is, you can check by inserting a SIM card from a different carrier into the device. In this case, you use 2 SIMs from 2 different carriers. If after insertion, the device receives signals and displays signal bars, then it is not an iPhone lock. But if either one of the SIMs fails to receive a signal, your phone is an iPhone locked to a carrier.

2.3 Verify iPhone lock using IMEI number
Another simple way to check iPhone lock, even for those not tech-savvy, is by verifying the IMEI number. There are 2 methods to check the iPhone IMEI:
- Method 1: Dial *#06# on the Phone app and call. The IMEI number will be displayed on the screen.
- Method 2: Go to Settings > General > About and check the IMEI number of the device.
Once you have the IMEI code, access the website checkcoverage.apple.com, enter the IMEI number and Captcha code, then press Continue, and all information about the device will be displayed.
2.4 Verify with ICCID code
ICCID (also known as SIM confirmation code) is a code pre-assigned by the manufacturer for each device, facilitating convenience in cases requiring device inspection. Therefore, you can check if your iPhone is locked by going to Settings > General > About > ICCID. If the first 4 digits of your ICCID are 8984, then it's an international version. Otherwise, it's an iPhone lock.
2.5 Using the SIM check feature on IOS 14
You can also determine what iPhone lock is by using the direct SIM check feature on IOS 14. Simply go to Settings > General > About. Under Carrier Lock, if your device shows SIM locked, it's an iPhone lock.
2.6 Seeking Apple's Assistance
For the most accurate check, you can call the Hotline 1800 1127 during office hours (from 9 am to 6 pm, Monday to Friday). This call is completely toll-free, and you can freely discuss your issues with support staff. If you're not fluent in languages, don't hesitate because Apple provides Vietnamese-speaking staff to assist you.
Alternatively, you can leave your information and schedule an appointment through the following steps:
- Visit the Apple homepage > select Support.
- Choose Apple Repair > Start a repair request.
- Select iPhone.
- Choose App and Feature > select Content not playing as expected.
- Schedule a call and provide the complete serial, IMEI, MEID numbers of the device.
- Choose the time you want to be contacted and leave your personal information, finally press Continue and wait for the system to confirm completion.

Seeking assistance from Apple employees is also a reliable method to check for iPhone lock.
3. How to Convert iPhone Lock to International iPhone?
There are 2 ways to unlock iPhone lock to international iPhone:
3.1 Purchase Unlock Code
You can purchase a code to unlock the iPhone. However, the cost of buying the code is very high, adding up to a total value that may even exceed that of an international phone, not only wasting time but also losing the advantage of the cheap price that the locked iPhone brings.
3.2 Using SIM Interposer
SIM interposer is a thin adhesive copper piece placed over a regular SIM card, enabling it to function like a carrier-sold SIM. However, using a SIM interposer often leads to issues such as battery drain, overheating, weak signals, corrupted contacts, phone account verification errors, software update glitches, etc.
