The short answer
eSIM routes your data through Hong Kong or another overseas server. You get a non-Chinese IP. Google, WhatsApp, Instagram, Gmail all work with zero configuration. It's the easiest path to getting online in China.
VPN encrypts your traffic and tunnels it through an overseas server. Works on Wi-Fi and cellular. Faster speeds for streaming and video calls. But the Great Firewall actively tries to block VPNs, so reliability fluctuates.
The best answer for most travelers in 2026: use both. eSIM as your primary data connection (bypasses the firewall on cellular), VPN as backup for Wi-Fi and when eSIM data runs low.

When you install a travel eSIM from Airalo, Holafly, or Ubigi, your phone connects to a local Chinese tower for signal but routes all data through an overseas server, typically in Hong Kong, Singapore, or Japan. This means your IP address is non-Chinese.
From the Great Firewall's perspective, your traffic looks like it's coming from Hong Kong. Google, YouTube, WhatsApp, Instagram, Facebook, Gmail, Twitter, Reddit, Wikipedia all load normally. No app installation, no configuration, no login. It just works.
The trade-off: eSIM data is more expensive than local Chinese SIM data, and speeds are slower because traffic makes an extra hop through the overseas server. Video calls and large downloads may lag.
How VPN works in China
A VPN creates an encrypted tunnel between your phone and a server outside China. All your traffic, whether on Wi-Fi or cellular data, flows through this tunnel. The firewall can't read the contents, so it can't block specific sites.
VPNs work on any connection: hotel Wi-Fi, cafe Wi-Fi, local Chinese SIM data, airport Wi-Fi. This is their biggest advantage over eSIM, which only covers cellular data.
The challenge: China's firewall actively detects and blocks VPN traffic. Premium VPNs use obfuscation (disguising VPN traffic as normal HTTPS) to evade detection. But the cat-and-mouse game is ongoing. Even the best VPNs have downtime.

The winning combo: eSIM + VPN
Here's what experienced China travelers do in 2026:
- Install a travel eSIM (Holafly or Airalo) before departure. This handles your cellular data. All Western apps work immediately on arrival.
- Install ExpressVPN on your phone and laptop. Use it when connected to Wi-Fi (hotels, cafes, airports) where eSIM doesn't apply.
- Buy a local Chinese SIM (China Unicom, ~$15) for a +86 phone number if you need SMS verification for Chinese apps like Alipay, DiDi, or 12306.
This three-layer approach covers every scenario: eSIM for cellular data with firewall bypass, VPN for Wi-Fi, and a local SIM for Chinese app verification.
