Best eSIM for China (2026): Set It Up Before You Land

By PabloEasy mode⏱ 10 min✔ Last verified October 2026

Short answer: The best eSIM for China is a travel eSIM that you buy and install before you fly. It uses a Chinese mobile network for signal but routes your data abroad, so Google, WhatsApp, Instagram and Gmail keep working. Pick the plan by trip length and how much you use your phone. Expect roughly $4–20 for a short trip and $30–75 for a month. Prices come from provider plan pages (see Sources) and change often.

Before you start

You need three things:

1. A phone that supports eSIM. iPhone XS or newer and most recent Pixel and Samsung flagships do. On iPhone, look for an EID under Settings → General → About.
2. An unlocked phone, not tied to your home carrier.
3. Wi-Fi at home (or in Hong Kong during a layover). Many providers’ eSIMs can’t be downloaded once you’re inside mainland China.

How to pick the right plan

Start with your trip, not the brand.

You are…	Choose	Typical price
Short trip, light use (maps, messages)	1–5 GB for 7 days	~$4–15
1–2 weeks, normal use	10–20 GB for 15–30 days	~$15–30
Heavy use, video calls, hotspot	Unlimited, day-based	~$4/day, $30–75/month
Business traveler needing calls	eSIM with voice minutes, or keep home roaming	varies

Then check these five things on the plan page:

• Network. Look for China Unicom and/or China Telecom. Plans on both switch to the stronger signal.
• Daily cap. Many “unlimited” plans slow down after a daily limit (e.g. 1–5 GB/day). Read the fair-use line.
• Hotspot. Some unlimited plans restrict tethering.
• Top-ups in the app, so you don’t need a new eSIM if you run out.
• Refund policy if it doesn’t connect.

Going to Hong Kong or Macau too? They are often sold as separate destinations. Pick a “China + HK + Macau” plan if you’re visiting all three.

Where to buy

Commonly used for China: Airalo, Yesim, Holafly, Nomad, Jetpac, Saily and Ubigi. They use the same basic approach. The differences are price per GB, network choice, daily caps and support. Prices change often, so compare on the day you buy. (Airalo and Yesim are affiliate links.)

Official sites: airalo.com and yesim.app. You buy, install and top up Airalo in its app, called Airalo.

Quick pick

Don’t want to compare? Airalo’s China eSIM is the most widely used option. Install it before you fly, and Google, WhatsApp and Instagram work on mobile data from the moment you land. (Affiliate link — same price for you.)

Our approach

We’re testing these on the ground and will publish a tested ranking. Until then, choose a plan that names China Unicom and/or China Telecom, fits your trip length, and has a clear refund policy.

Step by step

1. Check your phone supports eSIM and is unlocked (see above).
2. Buy the plan on the provider’s site or app, at home, on Wi-Fi.
3. Install the eSIM before you enter mainland China.

4. When you land, turn on the eSIM line and enable data roaming for it.
5. Set it as your default data line and turn off automatic data switching.
6. Turn off Wi-Fi when you need blocked apps. Hotel and café Wi-Fi are Chinese networks, so Google and WhatsApp won’t work on them. The list of blocked apps follows Freedom House, Freedom on the Net 2025: China.

Do you need a Chinese number?

Usually not. Alipay, WeChat, Didi and 12306 all accept international numbers for verification. A few local apps and restaurant queue systems want a +86 number. A dual-SIM setup solves that: local SIM for the number, eSIM for data. A local SIM needs passport registration in a store, and blocked apps won’t work on it.

If it doesn’t work

Problem	Why	Fix
Can’t download the eSIM in China	Many providers block installs from inside mainland China	Install before you cross, or during a Hong Kong layover
Google or WhatsApp won’t load	You’re on Wi-Fi, which is a Chinese network	Turn Wi-Fi off and use eSIM data
No data	Data roaming is off, or the wrong line is default	Enable roaming on the eSIM line and set it as default data
Data slows down	Daily cap on an “unlimited” plan	Check the fair-use line; top up in the app if needed
Won’t connect at all	Phone locked, or plan not for your area	Check the unlock status and plan region, then use the provider’s refund policy

FAQ

Is using a travel eSIM legal in China?

Yes. You’re using a licensed international roaming service, the same way your home carrier’s roaming works.

Can I make normal phone calls?

Most travel eSIMs are data only. Use WhatsApp, FaceTime or similar for calls, or choose a plan with voice minutes.

Is a travel eSIM better than a local SIM?

For blocked apps, yes. A local SIM gives you a Chinese number but blocked apps won’t work on it. A travel eSIM is the easiest option. Home roaming also works but is often expensive.
