Can Mobile Phones Purchased in China Use eSIM? A Complete Guide

Many travelers ask the same question before going abroad: “My phone was purchased in China. Can I install and use an eSIM?”

The short answer is: Some phones can, but it depends on the exact model, region of purchase, carrier support, and where you activate the eSIM.

As of August 2026, mobile eSIM services are available in mainland China. However, eSIM is still limited to selected approved devices, and support cannot be determined by the brand or series name alone.

What Is an eSIM?

An eSIM, or embedded SIM, is a digital SIM built into a mobile device. Instead of inserting a physical SIM card, users download a carrier profile by scanning a QR code or entering activation details.

Compared with a physical SIM card, an eSIM offers several advantages:

  • No physical card needs to be inserted or stored

  • Multiple mobile plans can be saved on one device

  • Travelers can purchase local or international data plans

  • An eSIM cannot be physically removed if the phone is lost or stolen

  • Manufacturers can reduce or remove the physical SIM-card tray

However, an eSIM is not simply an app or software feature. A phone must contain compatible eSIM hardware, and the feature must also be supported by the device manufacturer and mobile carrier.

Can Phones in Mainland China Use eSIM?

Yes, but only selected devices are currently supported.

China Mobile, China Unicom, and China Telecom offer mobile eSIM services for approved devices. Users generally need to take a compatible phone and valid identification to a designated carrier store to complete identity verification and activation.

Supported mainland China models include selected devices from Apple, Huawei, Samsung, OPPO, and HONOR. Examples include:

  • Apple iPhone Air and iPhone 17e

  • HUAWEI Mate 80 RS, Pura X Max series, and Pura 90 Pro Max

  • Samsung Galaxy S26 series, Galaxy Z Fold 8 series, and Galaxy Z Flip 8

  • OPPO Find X9 Pro Satellite Communication Edition

  • HONOR Magic8 Pro Air

This is not a complete list, and supported models may change frequently. Users should always check the latest information from the manufacturer and carrier before purchasing a phone or applying for an eSIM service. See the official guidance from Apple, Huawei, and Samsung.

Why Might a Phone Show “Add eSIM” but Still Not Work?

A phone must meet three requirements before it can use an eSIM.

1. Compatible hardware

The phone must contain an embedded eSIM chip and have an EID. The EID is a unique identification number for the device’s eSIM hardware.

2. Compatible software

The phone’s settings should include an option such as “Add eSIM,” “SIM Manager,” or “Scan to Add eSIM.”

3. Carrier approval

Even if the device contains compatible hardware, a carrier may reject activation if that exact model has not been approved or added to its supported-device list.

For this reason, a specification stating that a phone “supports eSIM” does not necessarily mean that it can activate an eSIM from a mainland Chinese carrier.

How Can I Check Whether My Phone Supports eSIM?

You can perform an initial check through your phone’s settings.

On an iPhone

Go to:

“Settings” → “General” → “About”

Look for an EID entry. You can also go to:

“Settings” → “Cellular” or “Mobile Data”

Check whether an “Add eSIM” option is available.

However, the presence of this option does not guarantee compatibility with mainland Chinese carriers. Only designated mainland China iPhone models can install eSIM profiles issued by mainland carriers.

On an Android phone

Go to:

“Settings” → “Mobile Network” → “SIM Manager”

Look for “Add eSIM,” “Scan to Add eSIM,” or a similar option. You may also find the EID under “About Phone.”

The same phone model may have different eSIM capabilities depending on whether it was sold in mainland China, Hong Kong, or another international market. Always verify the full model number rather than relying only on the product name.

Can a Mainland China Phone Use a Travel eSIM Abroad?

It depends on the device.

Some newer mainland China models can install an international or local travel eSIM after arriving outside mainland China.

For example, Apple states that the mainland China versions of the iPhone Air and iPhone 17e can activate an eSIM from a local carrier while traveling outside mainland China. However, an international carrier’s eSIM cannot be installed on these devices while they are physically located in mainland China.

Selected mainland China Samsung models have similar restrictions: users may install a local travel eSIM abroad, but cannot download an international carrier’s eSIM profile while in mainland China. See the official travel guidance from Apple and Samsung.

Before traveling, check the following:

  • Whether the mainland China version supports international eSIM profiles

  • Whether the eSIM can be installed before departure or only after arriving abroad

  • How many eSIM profiles the phone can store

  • Whether location services must be enabled

  • Whether the plan covers your destination and its local networks

If your phone can only install the travel eSIM after leaving mainland China, make sure you have access to Wi-Fi when you arrive.

Can an Overseas Phone Activate a Mainland China Carrier eSIM?

Usually not.

For example, Apple states that only designated mainland China iPhone models can install eSIM profiles from mainland Chinese carriers. Other iPhone models, including those purchased outside mainland China, cannot install these profiles.

However, an overseas phone with an international or travel eSIM may still connect to a partner network in mainland China if the plan includes roaming coverage there.

This is an international roaming service and should not be confused with activating a local Chinese mobile number.

What Is the Difference Between eSIM and International Roaming?

An eSIM is a type of SIM technology, while international roaming is a mobile service. They are not the same thing.

For example:

  • Using a Chinese carrier’s eSIM abroad with roaming enabled means using a Chinese number with international roaming

  • Purchasing a travel eSIM means adding a separate international or destination-specific plan

  • Using a physical SIM card abroad with roaming enabled does not require eSIM support

Many travel eSIM plans are data-only. They may not include a local phone number, voice calls, or SMS. Users should check the plan details before purchasing.

Conclusion

Mainland China has entered the mobile eSIM era, but restrictions still apply based on the phone model, sales region, carrier, and activation location.

The simplest way to check compatibility is:

Look for an EID, verify the phone’s full model number, and confirm support with the carrier or eSIM provider.

Travelers should pay particular attention to activation-location restrictions. Some mainland China phones can only download and activate an international travel eSIM after leaving mainland China.

As eSIM availability continues to expand, always refer to the latest guidance from the device manufacturer, mobile carrier, or eSIM provider before purchasing or activating a plan.
