Best eSIM for China (2026): for visitors travelling to mainland China

Why China is different

Mainland China filters its domestic internet, often called the Great Firewall. Airalo's help center lists Google (including Gmail and Maps), Instagram, Facebook, X, YouTube and WhatsApp as generally inaccessible on local networks. That covers hotel, café and airport Wi-Fi as well as a SIM card bought locally.

A travel eSIM is international roaming. It uses a Chinese operator's radio network, but providers say the data is carried to an internet gateway outside mainland China before it reaches the web. Airalo's help center puts it like this: "your traffic is routed through secure gateways outside mainland China", so your phone "appears as an international roaming user." Nomad's says the same and adds two caveats: exit points "vary depending on your plan and provider," and the eSIM "isn't a VPN, so your traffic isn't encrypted the way a VPN encrypts it."

What each provider says about Google and WhatsApp

Here the providers genuinely disagree, which is why we quote them instead of summarising:

• Airalo says no VPN is required on its China, Asia regional and Global eSIMs.
• Nomad says Google, Gmail, YouTube, WhatsApp, Instagram and Facebook work on its China eSIM data without a separate VPN, and warns that running a third-party VPN at the same time "may interfere" with the connection.
• Holafly says its China eSIM comes "with VPN included at no extra cost."
• Yesim advertises a "Built-in VPN" that lets you use WhatsApp, TikTok and other services.
• Saily takes a more cautious line. Its China FAQ says you will need a VPN for WhatsApp and for signing in to Google, points to Saily's own virtual-location feature, and notes that China restricts VPN use to licensed providers.
• Ubigi and Maya didn't address this on the plan pages we read.

We don't give instructions for getting round local rules, and nothing here is legal advice. If reaching a particular app matters for your trip, pick a provider that says, in writing, that it works, and keep its help page handy.

Quick picks

Step 1: Size your plan for China

Expect to use more mobile data in China than elsewhere. Airalo makes the point itself: if blocked apps only work on your eSIM, everything you'd normally do over hotel Wi-Fi (maps, messages, photo backups, social media) runs on mobile data instead. As a rough guide, maps and messaging use hundreds of megabytes a day, while video and video calls can use several gigabytes. These are general estimates, not measurements.

Step 2: Compare published prices

Unlimited plans by trip length

Lowest listed price in the row — means no plan of that length was listed. Saily sells unlimited China plans for 5 to 30 days "from US$22.99"; its site wouldn't let us read the price for each length, so it isn't in the table. Maya's global plan is priced separately (see Maya). Official pages, checked 4 November 2026.

Fixed-data plans

Lowest listed price in the row Validity differs, so compare the small print as well as the price. Nomad's 10 GB and 20 GB plans were on sale; regular prices are $22 and $30. Airalo also lists shorter, cheaper versions (for example 3 GB for 3 days at $9.50). Ubigi also lists 10 GB for 7 days ($14), 25 GB for 30 days ($33), and a 20 GB monthly subscription ($16 a month, which it says can be cancelled after 3 months). Yesim also lists 30 GB for $45.60. Official pages, checked 4 November 2026.

Step 3: Check the fine print

• Networks. Airalo lists China Unicom. Nomad uses China Unicom for unlimited plans and China Unicom or China Telecom for fixed plans. Saily names China Telecom and China Unicom, Ubigi names China Telecom, and Holafly lists China Mobile (CMCC).
• Unlimited isn't always unlimited. Ubigi's unlimited plan gives 5 GB a day at full speed, then 2 Mbps. Holafly says a fair-usage policy can slow speeds for up to a day and limits hotspot sharing to 1 GB a day. Yesim says speeds may be limited under the operator's fair-usage policy. For the others, check the plan details before you buy.
• Activation windows. Nomad starts a plan automatically 60 days after purchase if you haven't used it. Yesim gives 90 days, Saily 180 days, and Ubigi 6 months. Ubigi plans start when you arrive.
• No Chinese number. These plans are data-only. Saily sells an optional US phone number with call and text plans. Nomad advises registering WhatsApp with your usual number before you travel, because its eSIMs don't receive SMS codes.

The seven providers

Hong Kong and Macau

Hong Kong and Macau are separate destinations for mobile plans, and the domestic filtering described above applies to mainland China. A plan sold as "China" won't automatically cover them.

Will your phone work?

• eSIM-capable and unlocked. Apple lists iPhone XS, XS Max, XR or later. Settings → General → About should say "No SIM restrictions" next to Carrier Lock (full checklist).
• Bought in mainland China? Apple says that in China mainland only the iPhone 18 Pro, 18 Pro Max, iPhone Duo, iPhone 17e and iPhone Air support eSIM, and Saily warns that devices made and sold in mainland China don't support eSIM. Many older mainland models use two physical SIM cards instead.
• Bought in Hong Kong or Macau? Apple notes that certain iPhone models sold there have two nano-SIM slots. Check for Add eSIM in your settings before you buy a plan.
• Install before you enter. Nomad and Saily both say you can't buy a new plan once you're in mainland China. Install it at home on Wi-Fi (install guide).

Paying with Alipay and WeChat Pay

Mobile payment is the norm in mainland China, and it runs on mobile data, which is one more reason to land with a working eSIM. Both apps now accept foreign cards. According to a Beijing district government guide, Alipay accepts Visa, Mastercard, Diners Club and Discover, and WeChat Pay accepts Visa, Mastercard, Diners Club and JCB.

• Fees. No fee on a single payment of RMB 200 or less. Above that, 3% of the whole payment, according to the same official guides.
• Your bank may say no. The National Immigration Administration's guide notes that some card issuers reject the request to link a card. Set the apps up at home and call your bank if linking fails.
• Limits. The National Immigration Administration's guide gives limits of US$5,000 per payment and US$50,000 per year for foreign cards. Check what the app shows when you add your card.

Entry rules: the 240-hour visa-free transit

China's National Immigration Administration says nationals of 57 countries, including the US, UK, Canada, Australia, Japan and South Korea, can transit visa-free for up to 240 hours (10 days). You need an ordinary passport and an onward ticket to a third country or region with a confirmed seat and date. You must enter through one of 65 designated ports in 24 provinces and stay within the permitted areas. Work, study and journalism still need a visa. Check the NIA's official page for the current country list, ports and areas before you book.

Before you fly

1. 1

   Check your phone

   Make sure it’s unlocked and eSIM-capable, and remember that most phones bought in mainland China aren’t (how to check).

2. 2

   Buy and install at home

   Install on Wi-Fi before departure; you can't buy new plans once you're in mainland China. Keep the line off until you land.

3. 3

   Set up payments and messaging

   Add your card to Alipay or WeChat Pay, and register WhatsApp with your home number while you can still receive SMS.

4. 4

   Switch on when you land

   Turn on the travel line, enable data roaming for that line, set it as your mobile-data line, and use it rather than hotel Wi-Fi for foreign apps.

5. 5

   Check entry rules

   Confirm visa or transit eligibility on official government sources. Visa services such as iVisa exist, but the official government site is always the authority.
