Two Hidden Prerequisites for eSIM

When buying a travel data plan, the worst experience is spending money only to find out your phone doesn't support it upon arrival.
Buying blindly can easily lead to losing connection.
Taking one minute to confirm device compatibility before purchasing is the only way to ensure a smooth trip.
How to Check
1.Dial for EID
Simply put, the key is to check for something called an EID.
EID (Embedded Identity Document) is the unique hardware identifier for an eSIM.
Whether you use an Apple or Android device, this is currently the most accurate physical hardware detection method recognized in the industry.
- Open the "Phone" or "Dialer" app on your device
- Type *#06# on the keypad
- A screen containing your device information will automatically pop up
If it includes a 32-digit number, it means your phone has built-in.
If no EID is displayed, and you only see IMEI and MEID, your device does not support it.
2.iOS / iPhone
If you prefer not to use the dial method, you can visually confirm through the iOS system settings.
Apple's system hierarchy is highly unified. The verification steps are as follows:
1. Go to Settings> Cellular(or Mobile Data).
2. Scroll down and look for a blue button that says Add eSIM or Add Cellular Plan.
If this button is present, your hardware supports it.
However, please note that Apple has strict regional sales policies. You can refer to the Apple Official eSIM Support Document for more technical details.
3.Android
The Android ecosystem is more fragmented, and menu paths vary slightly between brands. Here are the check paths for mainstream Android brands:
Samsung: Settings > Connections > SIM Manager > Check for "Add mobile plan" or "Add eSIM".
If you still have questions about Samsung phone compatibility, you can click How to Check if Your Samsung Phone is eSIM Compatible (2026 Updated) for more details.
Google Pixel: Settings > Network & internet > SIMs > Tap the "+" icon > Check for a "Download a new eSIM" option.
Android menu names vary by system version.
If you cannot find the corresponding option in the paths above, please use the dial *#06# for final confirmation.
Two Hidden Prerequisites for eSIM
Even if your phone displays an EID, it must simultaneously meet the following two conditions to use a travel eSIM normally.
This is a blind spot that many beginners easily overlook.
1. Must Be "Carrier-Unlocked"
If your phone is tied to a specific carrier (like AT&T, T-Mobile, or SoftBank) through a contract, it will have a Carrier Lock. Even with eSIM functionality, this type of device cannot add data plans from other network providers.
- How to check on iPhone: Settings > General > About > Find "Carrier Lock". If it says "No SIM restrictions", you are safe.
2. Avoid Hardware Restrictions in Specific Regions
Due to local regulations, phones sold in certain regions have the eSIM module physically removed at the factory:
- Mainland China: All iPhones manufactured for Mainland China do not support eSIM (they only support dual physical nano-SIMs).
- Hong Kong/Macau: iPhone 13 and newer Pro/Pro Max models do not support it, but some iPhone SE and mini models do.
If you are using a phone from these restricted regions, we recommend preparing a backup plan before traveling. You can refer to the methods discussed in Alternatives for Chinese Phones Traveling Abroad
