Yes! most modern smartphones (iPhone, Samsung, Pixel, etc.) support eSIM functionality in mainland China, just as they would elsewhere. You can use your international or regional eSIM plan without swapping the physical SIM. However, there are some thing you have to consider about using mobile data in China, we’ll cover them today on this article.

Key features:
- Instant setup: Install your eSIM via QR code before your trip. Your plan activates as soon as you land and have mobile signals.
- No physical SIMs needed: Skip city-store visits and ID registration.
- Roaming bypass: Use local data deals without roaming charges from your home carrier.
- IMPORTANT: SIMs don’t bypass China’s internet firewalls. Whether you use eSIM or physical SIM, the Great Firewall still blocks major sites and apps, like Google, Facebook, WhatsApp, and Instagram
What is a VPN and why is so important for a traveler who is looking for internet in China?
A VPN (Virtual Private Network) is a secure tunnel between your device and the internet. It encrypts your internet traffic and routes it through a server in another location, hiding your IP address and protecting your data from surveillance, hackers, and internet restrictions.
In SIMPLE TERMS, when you use a VPN, websites and apps see the VPN server’s location instead of your physical location, allowing you to access content and services as if you were in another country. This is helpful for streaming, secure banking, and maintaining privacy on public Wi-Fi.
Why VPNs Are Important in China?
In China, the Great Firewall blocks many foreign websites and apps including Google, Gmail, WhatsApp, Instagram, Facebook, YouTube, and many news sites. Without a VPN, you will not be able to use these services, even if you have an eSIM with fast mobile data.
A VPN helps you bypass the Great Firewall, allowing you to access essential services like Google Maps for navigation, WhatsApp for messaging, and Gmail for work or travel confirmations. It also keeps your connection secure on public networks in cafés, airports, and hotels.
However, not all VPNs work in China due to strict internet controls. You need to choose a reliable, paid VPN with obfuscation technology, such as NordVPN, ExpressVPN, or Astrill. It is crucial to download and set up your VPN before arriving in China, as many VPN websites are blocked inside the country.
In summary, a VPN is essential for travelers to China who need access to Google services, social media, and a secure, unrestricted internet connection while using their eSIM or local network.
Unfortunately, China blocks many global services, including:
- Google Maps, Search, Gmail WhatsApp, Instagram, Facebook, Twitter YouTube, Netflix
As we mentioned before, to access these, you need a VPN (Virtual Private Network) with reliable obfuscation features to disguise traffic from the Great
Choosing the right VPN:
Use established providers known to work in China, such as:
- NordVPN (NordWhisper protocol)
- ExpressVPN
- Surfshark
- Astrill VPN
Install the VPN before you leave, since VPN websites are blocked once you’re in China
REMEMBER: The Great Firewall only applies in mainland China. Hong Kong and Macau still provide unrestricted internet
Why Simsolo is an excellent eSIM choice for China?
Simsolo offers a dedicated China eSIM with flexible plans and competitive prices. Here’s why they’re a strong option:
- Simple activation: QR code arrives instantly after purchase, letting you install before departure.
- Flexible data packages: Choose between fixed-size data or daily unlimited plans to match your usage.
- High-speed networks: Simsolo connects to trusted local telecom providers, like China Mobile or China Telecom.
- Hotspot support: Tether your laptop or tablet on the 4G/5G network.

4. What you can and cannot access with eSIM alone?
Without a VPN, your eSIM connection allows access to:
- Chinese apps like WeChat, Baidu, Taobao, and domestic mapping services.
- Local websites and services.
- Email and fintech apps that operate in China.
Remember, foreign apps remain blocked unless you use a VPN:
- WhatsApp, Gmail, Google Maps: Blocked without a VPN.
- Facebook, Instagram, Twitter: May be inaccessible.
- News outlets: Sites like New York Times or BBC online often blocked.
Some travelers report that eSIMs paired with roaming from a non-Chinese carrier may allow limited access, but this is unreliable and may incur high cost.
5. Combining eSIMs with VPNs
Here’s a practical setup for traveling in China:
- Before departure:
- Purchase and install your eSIM (e.g., Simsolo).
- Purchase and install a China-compatible VPN like NordVPN or Astrill.
- Upon arrival:
- Activate mobile data via the eSIM.
- Enable VPN before opening any apps.
This setup lets you use:
Maps, Google services , WhatsApp, Instagram, YouTube , Navigation apps without needing physical SIM or Wi-Fi
Hotspot/tethering: you can share the VPNed eSIM connection with your laptop, tablet, or travel companion.
Final tips
- Physical SIMs are sold at airports but require ID registration and may still block foreign apps without a VPN.
- Always connect to VPN when opening blocked apps—forgetting may prevent access.
- Occasionally the VPN might drop; if so, reconnect quickly.
