How to Buy an eSIM for China: A Step-by-Step Guide (With VPN Considerations)
To buy an eSIM for China, confirm your phone is unlocked and eSIM-compatible, choose a provider, and purchase and install the plan before departure. After landing, activate it with data roaming. Some international eSIMs may bypass China's internet restrictions, but VPN access varies by provider.
To buy an eSIM for China, you need to purchase and install it online before you depart, since new eSIMs cannot be installed once you're already inside mainland China. Getting this order right matters more than which specific provider you choose.
Your phone needs to be unlocked and eSIM-compatible, and depending on where it was bought, especially if it's a mainland Chinese iPhone, that alone might rule out most models.
Once that's settled, the bigger question most travelers actually care about is whether Google and WhatsApp will work without a VPN, and that depends more on your provider's routing than on the eSIM itself.
Working through how to buy eSIM for China properly, in the right order, is what actually determines whether any of that works once you land.
Step 1: Confirm Your Phone Qualifies
Your phone needs to be fully carrier-unlocked, and it needs native eSIM support. If your iPhone was bought in mainland China, only the iPhone 17e and iPhone Air currently support eSIM there; every other mainland-bought model ships with two physical SIM trays instead and can't use eSIM technology at all.
Hong Kong and Macau support a wider range of models, though still not every one. If your phone was bought outside mainland China, Hong Kong, or Macau and is unlocked and eSIM-compatible, it will work normally.
Step 2: Choose a Provider
Airalo, Nomad, and Klook are among the more established options for China, each connecting through China Unicom or China Telecom depending on the plan, with pricing generally starting around $4 for a small data allowance and scaling up from there.
Jetpac also offers a China eSIM, data-only like the others, with WhatsApp working normally even after your data pack runs out, and hotspot sharing with no data cap.
Step 3: Buy and Install Before You Fly
Select your plan and pay for it while you still have a normal internet connection. You'll get a QR code by email, and scanning it under your phone's cellular settings adds the eSIM profile.
Label the line something you'll recognize later, and leave data roaming switched off for now. Installing the profile isn't the same as activating it, and that distinction matters once you land.
Step 4: Activate After You Land
Once you're in China, switch to the new eSIM as your primary data line and turn on data roaming specifically for it. Turning off data on your home SIM at the same time avoids accidental roaming charges from your own carrier.
What About the VPN Question
Some international eSIMs route data through servers outside mainland China, which can let Google, WhatsApp, and Instagram work without a separate VPN.
This isn't guaranteed across every provider or plan, and independent testing has found at least one major provider's China connection routed through a domestic Chinese network instead.
Jetpac's eSIM for China keeps Google blocked, the same as it would be on any connection inside the country, while WhatsApp works normally. A pre-installed VPN is worth having as backup regardless of which provider you choose, which is really the safest way to think through how to buy eSIM for China without assuming every plan behaves the same way.
One Local Number Caveat
Most travel eSIMs, Jetpac included, don't come with a Chinese phone number. Alipay and WeChat Pay both work fine with a foreign number linked to a foreign card, so daily payments aren't a problem.
Booking train tickets through the official 12306 platform and registering for on-train Wi-Fi do typically require a +86 number, so a physical SIM from a China Unicom or China Telecom counter is worth considering if your trip depends on either.
