Does eSIM work in China?

Yes, if your phone supports eSIM and is not locked to one operator, and the eSIM plan includes China. Simbye lists iPhone XS and XR and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. A vendor blog (Jetpac) says phones sold in mainland China are mostly limited to physical SIMs, so check a phone bought in China separately.

Do I need a VPN with an eSIM in China?

It depends on where your eSIM sends your data. eSIMDB says some travel eSIMs exit through Hong Kong, so the Great Firewall does not apply. Simbye says Google, WhatsApp and Instagram are blocked on local connections in mainland China and its China eSIM runs on China Mobile there. We have not tested any eSIM from inside China, so we cannot say which one needs a VPN.

Do I need to register for a SIM card in China?

For a local Chinese SIM, yes. Wise says China requires real-name registration for anyone activating a SIM and you may need to show your passport. Simbye says buyers of a local SIM sign up at the counter with a passport, and that its eSIM needs no registration. We have not checked this in person.

Can I buy an eSIM after I land in China?

It may not work. In OONI tests from China (1 September to 5 October 2026) airalo.com did not load in any of 6 tests, airhubapp.com in none of 7, and nomadesim.com in none of 5. For several other stores, including Simbye and Holafly, OONI has no tests in that period. Buy and install your eSIM before you leave.

Does Airalo work in China?

Airalo's website did not load in OONI tests from China: 0 of 6 tests loaded between 1 September and 5 October 2026. That is only the store website. We did not test whether an Airalo eSIM connects in China or where it sends your data.

Which eSIM is best for China?

We cannot name a tested best yet. We have not tested any eSIM from inside China. The thing to look for is a plan that says clearly where your data exits (for example Hong Kong) and which network it uses in mainland China. Simbye is one option we list, with its limits explained above, not a tested pick.

How much is a Simbye eSIM for China?

On 6 October 2026, as shown to us from a connection in Germany, Simbye listed 1 GB for 7 days at 2.95 euros, 5 GB for 30 days at 9.95 euros, 10 GB for 30 days at 19.95 euros, 20 GB for 30 days at 23.95 euros and 50 GB for 180 days at 47.95 euros. The page title shows 'from $2.99', so the store may show dollars in your country.

eSIM for China (October 2026): Roaming vs Local SIM

Short answer (6 October 2026): an eSIM can work in China, but we cannot yet tell you which one gets you past the firewall, because we have not tested any from inside China. What decides it is where the eSIM sends your data. A third-party site says some travel eSIMs send data out through Hong Kong, so blocked apps work. A local Chinese SIM does not do that. What we can show is which eSIM store websites load from China, using OONI measurements by volunteers in China, 1 September to 5 October 2026. Most of the stores OONI tested did not load.

Do eSIM stores load from China?

OONI probes in China tried each store’s website. “Loaded / total” is the count of normal loads out of all tests. Click a number for the raw data. Last checked 6 October 2026. Our full method and labelling rule are on the what is blocked in China page.

OONI measurements from probes in China, 1 Sep to 5 Oct 2026. Last checked 6 Oct 2026.
Service	Result	Loaded / total tests	Note
Airalo (eSIM store) airalo.com	Blocked	0 / 6
Holafly (eSIM store) holafly.com	Too few tests	0 / 0	No OONI measurements in the period for this hostname (also none for www or esim subdomains).
Simbye (eSIM store) simbye.com	Too few tests	0 / 0	No OONI measurements in the period for this hostname (also none for www).
Airhub (eSIM store) airhubapp.com	Blocked	0 / 7
Nomad eSIM (store) nomadesim.com	Blocked	0 / 5

What this means: Airalo, Airhub and Nomad eSIM store websites did not load in any test. For Holafly and Simbye, OONI has no tests in the period, so we cannot say either way. A store website that does not load does not prove the eSIM itself fails once installed. It does mean you should buy and install before you travel.

Roaming eSIM or local SIM

	Roaming or travel eSIM	Local Chinese SIM
Where your data may exit	Depends on the plan. eSIMDB says many low-cost China eSIMs exit through Hong Kong.	On a Chinese network, so the same blocks as the OONI table
Registration	Simbye says its eSIM needs none	Real-name registration; Wise says you may need your passport
Set-up	Install before you fly	Online before travel or in China; Wise lists several options
Phone number	Usually data only (Simbye’s China eSIM has no number)	Yes
Status	We have not tested where any exits	Blocked sites in our table apply

Sources: eSIMDB, Simbye, Wise (all opened 6 October 2026). The Hong Kong claim is from eSIMDB, a commercial comparison site. Treat it as a claim, not a measurement. It also says apps such as ChatGPT may still have their own restrictions on a Hong Kong IP address.

What to check before you buy

Where does the data exit? Look for a plain statement such as “data routed via Hong Kong”. If the page does not say, assume it may be on the local Chinese network.
Which network does it use in mainland China? Simbye names China Mobile (and China Mobile Hong Kong, 3 Hong Kong and CTM in Hong Kong and Macao).
Is your phone eSIM-capable and unlocked? Simbye lists iPhone XS and XR and later, Samsung Galaxy S20 and later, Pixel 3 and later. Jetpac says phones sold in mainland China are mostly limited to physical SIMs.
Do you need a number? Data-only eSIMs cannot receive SMS codes. Keep your home SIM active for those.
When does the plan start? Simbye says validity starts at your first connection at the destination.
Install and test at home on Wi-Fi, then keep the phone in aeroplane mode until you land.

What the Simbye page says (opened 6 October 2026, shown to us from a connection in Germany, so prices appeared in euros):

Plan	Data	Valid	Price
1	1 GB	7 days	2.95 euros
2	5 GB	30 days	9.95 euros
3	10 GB	30 days	19.95 euros
4	20 GB	30 days	23.95 euros

Maths: 5 GB works out at about 2 euros per GB, 10 GB at about 2 euros per GB, 20 GB at about 1.20 euros per GB and 50 GB at about 0.96 euros per GB. Between the 10 GB and 20 GB plans you pay 4 euros more for 10 GB extra.

What the page also says, and what it does not:

It covers mainland China, Hong Kong and Macao, with one plan. In mainland China it runs on China Mobile, not China Unicom.
It says: “Google, WhatsApp and Instagram are blocked on local connections in mainland China, but not in Hong Kong and Macao. We will not promise you they work everywhere on the road.” This is Simbye’s own warning, and it suggests that you should not assume the plan gets you past the firewall.
It does not say where your data exits. We have not confirmed this with Simbye. We will ask them, and until they answer, check the plan details yourself.
It says the eSIM needs no registration and has no phone number.
We did not check Simbye’s refund policy for this page.

How we checked

Store websites: OONI aggregation API, probes in China, 1 September to 5 October 2026, opened 6 October 2026. These are remote measurements by volunteers, not our tests. We did not test from inside China ourselves.
Simbye: we opened the China plan page in a browser on 6 October 2026 and read the plans, network list and FAQ answers.
Other claims: from the sources listed below, each opened on 6 October 2026. The eSIMDB and Jetpac pages are written by companies that sell or compare eSIMs.
Not done: no eSIM was installed or used inside China by us.
