When planning a trip to China, staying connected is paramount. Whether it's for navigation, mobile payments, translation, or keeping in touch with family and friends, reliable internet access is indispensable. Traditional physical SIM cards require in-store purchase and real-name registration, while eSIM (embedded SIM) — a digital SIM card — is becoming the preferred choice for more international travelers. It's not only convenient and fast but can also help you easily access restricted international websites and apps within China.
What is eSIM? Why is it an Ideal Choice for China Travel?
An eSIM is a virtual SIM card embedded directly into your phone or other devices. It eliminates the need for physical swapping; you can activate cellular network services by scanning a QR code or downloading a profile in your device settings.
Advantages of eSIM:
- Instant Activation: Activate quickly by scanning a QR code before departure or upon arrival in China, saving you the time of queuing to buy a physical SIM card.
- No Physical Card Swap Needed: Keep your existing physical SIM card active while using the eSIM for data, enabling "dual SIM" functionality to receive calls on your original number.
- Bypass the "Great Firewall" (GFW): Many international eSIMs for China route data through servers outside mainland China (e.g., Hong Kong), allowing access to Google, WhatsApp, etc., without a separate VPN.
- Cost-Effective: Compared to international roaming, eSIM plans are typically more economical, offering flexible data options.
- Eco-Friendly and Convenient: Reduces the production and disposal of plastic SIM cards.
eSIM Device Compatibility
Not all phones support eSIM functionality. Before purchasing an eSIM, ensure your device is eSIM-compatible and "carrier-unlocked" (i.e., not tied to a specific carrier).
- Compatible Devices: Most newer iPhones (iPhone XS and later), Samsung Galaxy S20 and later, and Google Pixel 3 and later support eSIM. Note that US-version iPhones from 14 onwards are eSIM-only.
- Mainland China Phones: Phones sold in mainland China (regardless of brand) typically do not support international travel eSIMs.
- China Carrier Support: While Chinese carriers support eSIM, it's primarily for locals. International travelers should opt for third-party eSIM providers.

Choosing eSIM Plans via Alipay
Some international travelers can also purchase eSIM plans through specific services within the Alipay App. You can search for "eSIM" or "International Data" on the Alipay App homepage to find relevant service entry points. Be sure to carefully read the plan details to confirm if it supports use in mainland China and includes GFW bypass functionality.
Hong Kong eSIM Providers: The Advantage of Bypassing the "Great Firewall"
It is particularly recommended to consider Hong Kong (HK) based eSIM providers. The advantages of these eSIMs are:
- Bypass the "Great Firewall": As data traffic is typically routed through Hong Kong servers, these eSIMs can effectively bypass mainland China's "Great Firewall," allowing you to access international services like Google, WhatsApp, and Instagram without an additional VPN.
- Stable Network: Hong Kong operators generally have good cooperation with mainland Chinese operators, providing stable network connectivity.
You can inquire about eSIM products from major Hong Kong telecom operators (such as China Mobile Hong Kong, csl, or 3HK) through their official websites.
Internet Access in China and the "Great Firewall"
Internet access in mainland China is restricted by the "Great Firewall" (GFW). Many international websites and apps (such as Google, Gmail, YouTube, Facebook, Instagram, WhatsApp) are not directly accessible.
- eSIM Advantage: Many international eSIM services help you bypass the GFW by routing data traffic through servers outside mainland China.
- If eSIM Does Not Include VPN: If your chosen eSIM plan does not include GFW bypass functionality, you will still need a reliable VPN. It is crucial to download and install a VPN before your departure.
Practical Tips and Alternatives
Practical Tips:
- Download Essential Apps in Advance: Before arriving in China, be sure to download apps like Alipay, WeChat, Amap/Baidu Maps, and translation apps.
- Save eSIM QR Code: Screenshot and save the eSIM QR code to your device's photo gallery or print it out.
- Turn Off Background Data: To conserve data, you can turn off unnecessary background app data refresh.
Alternatives:
- Physical SIM Card: Purchase a local physical SIM card upon arrival, which requires real-name registration and usually does not come with built-in VPN functionality.
- International Roaming: Convenient but usually more expensive, and may not bypass the GFW.
- Portable Wi-Fi Device: Rent a "Wi-Fi egg," but be mindful of its battery life and VPN functionality.

eSIM offers unprecedented convenience and flexibility for international travelers heading to China. By planning ahead and choosing the right eSIM plan, you can ensure constant connectivity during your trip, enjoy the convenience of digital life, and easily access the international information you need.
