What is an eSIM?
eSIM stands for "embedded SIM." It's a digital version of the traditional SIM card. Unlike physical SIM cards, eSIMs are embedded directly into the device. This means users can activate a cellular plan without inserting a physical card.
The convenience of eSIM technology is undeniable. With eSIM, you can switch between different mobile carriers with ease. It eliminates the need for multiple SIM cards, offering users flexibility and freedom. For globetrotters, the ability to manage mobile plans in different countries seamlessly is a significant advantage.
Does China support eSIM?
Yes, but with limitations.
As of 2025, mainland China has limited support for eSIM, and it primarily applies to smartwatches and IoT devices rather than smartphones. Major Chinese carriers like China Mobile, China Unicom, and China Telecom currently do not provide eSIM services for mobile phones in most provinces.
However, Hong Kong, Macau, and Taiwan support eSIM for mobile phones, and many international travelers take advantage of this by using cross-border or international eSIM services.
Can I use eSIM in China?
Yes.
China does not ban the use of eSIMs, so if your device already has one installed, you can still stay connected by using international eSIMs from providers like ByteSIM. Their travel eSIMs connect through local Chinese networks via roaming or partnerships, providing reliable 5G/4G/LTE speeds and solid coverage. They work with most unlocked, eSIM-compatible smartphones, including iPhones, Samsung Galaxy models, and Google Pixels. Please note that most (basically all) Chinese phones do not support eSIM, no matter whether it's OPPO, Xiaomi, or iPhone.
How to Get an eSIM in China
While China’s domestic support for eSIM remains limited, international travelers can absolutely use eSIM through third-party providers. With easy activation, no paperwork, and instant connectivity, eSIM is the smart choice for visiting China in 2025.
Whether you're traveling for business, leisure, or studying abroad, an eSIM for China is a convenient, secure, and reliable option.
Purchase a tourist SIM card
China’s three primary mobile service providers are China Mobile, China Unicom, and China Telecom. All three offer tourist-friendly data packages, and physical SIM cards can typically be purchased upon arrival at major airports across the country.
Keep in mind that using a local SIM from any of these carriers may come with network-level limitations, meaning access to certain websites or apps could be restricted.

FAQs about China eSIM
How much data do I need when traveling in China?
The amount of data you’ll need largely depends on your travel habits and phone usage. Roughly 3-5 GB per week (Maps, music streaming, and regular social media updates) is enough. You can also refer to this guide to estimate how much data you will need.
Can you keep your phone number with eSIM?
Yes. Actually, eSIM will not affect other settings. You can choose eSIM as Mobile Data and primary SIM card as Default Voice Line to receive calls and messages.

No. Most eSIM plans are data-only. You won't receive a phone number along with your eSIM plan, but you can still use WhatsApp, Google, and Skype as usual.
