eSIM adoption is skyrocketing globally at an incredible pace. Whether you’re traveling abroad or looking to use a dual-SIM setup at home, eSIMs offer unmatched convenience.

Before you purchase your South Korea eSIM, it is crucial to verify if your device is actually compatible. This guide covers exactly how to check your phone's eSIM support for both iPhone and Android.

1. iPhone & iPad eSIM Compatible Models

To use an eSIM on an Apple device, you first need to ensure you are running iOS 12.1 or later.

Important Exceptions (Read Carefully):

Exceptions: Only certain iPhone SE (2nd gen) and iPhone XS models from HK/Macau may support eSIM.
Note: eSIM plans designed for smartphones cannot be used on iPads.

2. Android eSIM Compatible Models

Unlike iOS, Android does not have a single required OS version for eSIM, as compatibility depends on the hardware manufacturer.

(1) Samsung Galaxy eSIM Support

Korean Release Models: All Galaxy S23, S24, S25 series; Galaxy Z Flip 4-7; Galaxy Z Fold 4-7, SE; Galaxy A35/A54/A55 5G; Galaxy Tab S9 & S10.
International Release Models: All Galaxy Note 20; All Galaxy S20-S25 series; All Galaxy Z Flip & Z Fold series; Galaxy A34, A35, A54, A55 5G.

(2) Google Pixel & Others

Other Models: Motorola Razr/Edge/G; Huawei P40/Mate 40/Pura 70 Pro; Xiaomi 12T/13/14; Nuu Mobile X5.

3. How to Check eSIM Support on iPhone (Fastest Way)

The most reliable way to confirm compatibility isn't just looking at the model name, but checking your specific device settings.

(1) Method 1 (Settings):

step1. Go to Settings → General → About

(iPhone eSIM compatibility check: A blue circle highlights the "About" option in the Settings → General menu for device support verification.)

step2. Scroll down to find the IMEI number. If an IMEI number is listed under 'Digital SIM', your device definitely supports eSIM.

(Digital SIM confirmation: A blue box highlights the IMEI section under the Digital SIM category on an iPhone to verify eSIM activation capability.)

(2) Method 2 (Dial Code):

Simply dial *#06# on your phone and confirm the EID number listed.

(EID verification display: A smartphone screen showing the unique EID barcode and identification number used for embedded SIM registration.)

4. How to Check eSIM Support on Android Devices

If you aren't sure if your Android phone is a "Global" or "Regional" model, use these steps:

(1) Method 1 (Settings): Go to Settings → About Phone → Status Information. Look for an EID number.

(2) Method 2 (Dial Code): Open your dialer and enter *#06#. If an EID appears, your phone is eSIM-ready.

5. Crucial Step: Checking for Carrier Lock or Country Lock

Even if your phone supports eSIM hardware, it might be restricted by a Carrier Lock (SIM Lock). Your device must be "Unlocked" to use an international eSIM.

How to check for SIM Lock on iPhone:

step1. Go to Settings > General > About.

(Carrier lock status check: A blue circle highlights the "About" section in iPhone settings to verify network provider restrictions and SIM status.)

step2. Scroll down to "Carrier Lock" (or "Network Provider Lock").

(Unlocked device status: A red box highlights the "No SIM restrictions" confirmation to ensure the smartphone is compatible with third-party eSIM profiles.)

If it says "No SIM restrictions," you are ready to install any eSIM.

6. Frequently Asked Questions (FAQ)

Q1. How can I quickly check if my phone supports eSIM?
A: The fastest way is to dial *#06# on your phone. If an EID number appears on the screen, your device is eSIM-compatible.

Q2. Why is my eSIM not working even if my phone is compatible?
A: Your phone might be Carrier Locked. Ensure your settings show 'No SIM restrictions' before installing an international eSIM.

Q3. Do iPhones from China support eSIM?
A: Generally, iPhones purchased in Mainland China, Hong Kong, and Macau do not support eSIM as they are designed with dual physical SIM slots.

7. Conclusion

Before you order an eSIM service for your next trip, always double-check these three things:

Is my model on the compatibility list?
Does my device have an EID number?
Is my phone Carrier Unlocked (No SIM restrictions)?

Once these are confirmed, you can enjoy a high-speed, hassle-free connection in Seoul!
