Is Your Phone eSIM Compatible? Check Before You Buy

2026年7月12日

eSIM = no physical SIM card, no shipping, scan-to-install digital SIM

Please do not buy before confirming that your phone supports eSIM.

An eSIM is a digital SIM profile built into a compatible phone. It is not a plastic SIM card, and no physical SIM will be shipped. After payment, you receive an eSIM configuration or QR code and install it on a phone that supports eSIM.

Why compatibility matters before buying

eSIM activation depends on more than the package itself. Your phone model, sales region, carrier lock status, eSIM profile limit, installation environment, and the country or region supported by the plan can all affect whether the eSIM can be added successfully.

For iPhone users, do not judge only by names such as iPhone 14, iPhone 15, iPhone 16, or iPhone 17. Many iPhones sold in Mainland China do not support the regular add eSIM function. Hong Kong, Macau, US, European, and other regional versions may also differ. The most reliable check is your phone settings page.

Step 1: Check the add eSIM option

On iPhone, open Settings → Cellular or Mobile Data, then look for “Add eSIM” or “Add Cellular Plan.” On Android, open Settings → SIM cards and mobile networks, Connections, or SIM Manager, then look for “Add eSIM” or “Download SIM.” If this option is missing, do not place an order yet.

Step 2: Check EID

Open the dial pad and enter *#06#. If the screen shows an EID, the phone generally has eSIM hardware support. However, EID alone does not guarantee activation. You still need to confirm the add eSIM option, region version, and carrier lock status.

Step 3: Check carrier lock

On iPhone, open Settings → General → About → Carrier Lock. It should show “No SIM Restrictions.” If the device is locked to a carrier, it may fail to install or use another operator profile.

Simple decision guide

Result A: Usually OK to buy

Your settings show Add eSIM, the dial page shows EID, and carrier lock says No SIM Restrictions. Confirm the destination and plan rules before payment.

Result B: Do not buy yet

Your phone shows EID but does not show Add eSIM. This may be caused by regional version, system, or carrier restrictions.

Result C: Do not buy

No EID and no Add eSIM option usually means the current device does not support eSIM.

Before installation

Use stable Wi-Fi for first installation. Do not wait until you have no internet at the airport.
Display the QR code on a computer, tablet, or another phone, then scan it with the phone that needs the eSIM.
An eSIM QR code usually can be added successfully only once. Do not repeatedly scan, delete, or move it between devices.
After arriving at the destination, turn on data roaming according to the plan instructions.

After your phone passes the checks, you can buy the China eSIM through the main Taobao product link: China Mainland eSIM on Taobao. To compare more countries and data plans, visit the Taobao store. You can also visit ChinaCheckPick.com. If you need supplier background checks before a China business trip, see VerifyChinaX supplier verification service.

Important after-sales boundary

Customers are responsible for confirming device compatibility before ordering. If the phone does not support eSIM, has a carrier lock, the wrong regional plan was purchased, the QR code was deleted, the profile was repeatedly added, or instructions were not followed, the issue is normally not considered a product fault.

If the platform or plan itself appears abnormal, please provide the phone model, EID page, add eSIM page, error screenshot, and order information for checking. eSIM is not a VPN, and it does not guarantee that every overseas app will work in every network environment. Actual availability can be affected by plan routing, IP exit, local network, phone settings, operator policy, and app service policy.
