China eSIM: which provider actually works on arrival

For most phones, the dependable choice is an international eSIM bought and installed before you fly. Airalo, Holafly and Saily all sell mainland China data plans, and they differ on three things that decide your trip: where the data exits, whether hotspot works, and what the plan cannot do. A local SIM is cheaper per gigabyte, but it costs you a passport queue at the airport.

Do Airalo, Holafly and Saily work in mainland China?

Yes, all three sell data plans that connect to a mainland network, and all three expect you to install the plan before you fly and switch it on when you land. They are roaming products, not Chinese phone lines. Your data travels through the provider’s own network, you keep your home number, and you do not get a Chinese one.

That difference drives the rest of this comparison. A local SIM is a Chinese line on a Chinese network, so mainland restrictions apply, but SMS works and hotspot usually does. An international eSIM is a visitor’s line: no texts, no restrictions in most cases.

Check one thing before you compare prices: your phone must be carrier-unlocked and eSIM-capable. Mainland carriers only began commercial eSIM trials for phones in October 2025, after approval from the Ministry of Industry and Information Technology, so support still depends on the handset model. The full China eSIM guide covers arrival.

Which of the four options fits your trip?

The table compares the three international providers with a local SIM and a home-carrier roaming pass. Read the last column first: it names what each option does not tell you, which is where arrival-day surprises come from.

China connectivity options for a foreign visitor, as of October 2026.

Option	Plan model	Where the data exits	Hotspot	What it does not tell you
Airalo	Fixed data sold by gigabyte and by days	Its help center says no VPN is needed, which implies routing outside the mainland	Set per plan; check before buying	Whether your exact handset and plan match the routing in its help center
Holafly	Unlimited data sold by days	Its China page states a VPN is included for restricted apps	Sharing allowed, 1 GB a day on the China plan	How “unlimited” behaves after a heavy day of video or hotspot use
Saily	Data plans by gigabyte and by days, managed in the app	App-managed; confirm the route on the plan page	Plan-dependent; check inside the app	Which mainland network you will see, and what the app does if activation fails
Local SIM from China Mobile, China Unicom or China Telecom	Prepaid voice and data, bought in a store	Mainland network, so mainland restrictions apply	Normally allowed	The counter’s English, its stock that day, and the plan that is actually on sale
Home-carrier roaming	Your own plan, billed per day or per trip	Your home operator, usually outside the mainland	Follows your plan	The daily cap and the throttle that starts after it

None of these rows is a ranking. Plans change often, and a feature allowed this month may not be next. The provider’s own page is the only current source, which is why every link here goes to the provider.

Does a China eSIM get around mainland filtering?

Usually, but not because of anything clever the eSIM does. A travel eSIM is a roaming line: your traffic is handed to the provider’s home network before it reaches the open internet, so services that are blocked on a mainland connection often load normally. Providers describe this differently, and some plans route locally instead.

Two examples show how uneven the disclosure is. Airalo’s help center says its China eSIM needs no VPN, while Holafly sells a VPN with its plan. Those claims cover their own products, not every plan under the brand. Look for a sentence that says where the data exits.

Do not turn a data plan into a work plan. Video calls add latency, and routing can change between trips. The internet and apps guide covers the detail. If a call matters, carry a second option that does not depend on one provider.

Is hotspot allowed on a China eSIM?

Sometimes. Holafly’s China page says you can share 1 GB a day, and that the total depends on plan length: a seven-day plan shares about 7 GB. Airalo and Saily set rules per plan, so one package can allow tethering while another blocks it. A local SIM normally allows it.

This matters only if you travel with a laptop or second phone. A phone-only trip does not need hotspot, so filter on price and routing first. If you do need it, screenshot the plan’s hotspot line before you buy: it is the first thing support will ask for.

What does a China eSIM cost per gigabyte?

There is no single price. Fixed-data plans get cheaper per gigabyte as the bundle grows, while unlimited plans are priced by the day and hide their cost in the fair-use limit. The bands below are editorial estimates checked on 29 October 2026, not quotes. Confirm on each provider’s pricing page.

Typical price shapes for China data, editorial estimate as of October 2026.

Plan shape	Typical band	What drives the per-gigabyte cost
3 to 5 GB, 7 days, data-only eSIM	About USD 5 to 15	The smallest bundles carry the highest per-gigabyte rate
10 to 20 GB, 15 days, data-only eSIM	About USD 15 to 30	Whether hotspot is included and which network it roams on
30 days, unlimited or 20 GB or more	About USD 25 to 45	Fair-use speed limits and the daily sharing allowance
Local prepaid SIM from a Chinese carrier	Lowest cost per gigabyte	In-person registration and what the counter sells that day
Home-carrier roaming pass	Usually charged per day	Your operator’s daily add-on and its cap

The pattern is simple: per-gigabyte cost falls as the bundle grows, so a light user pays more per gigabyte. A week of maps and messaging fits the first row. Add hotspot or photo backup and you move down. Judge the number against the China travel budget.

What happens at the airport if you land without data?

SIM counters sit in the arrivals halls at Beijing Capital, Beijing Daxing, Shanghai Pudong and Guangzhou Baiyun, and they sell tourist plans. Expect a passport check, a real-name step and a queue. Airport Wi-Fi is no rescue: many public networks text the login code to a Chinese number you do not have.

Real-name registration is a legal requirement, not shop policy. You show a document, the operator records it, and the SIM activates against your identity. That rule is also why nobody can buy a local SIM for you in advance.

Under the Ministry of Industry and Information Technology’s telephone user real-name registration rules, a carrier must check a valid identity document and record the user’s real identity before it activates a mobile phone line. A foreign citizen’s passport is listed as one of the accepted documents. Close paraphrase of Ministry of Industry and Information Technology Order No. 25, promulgated 16 July 2013 and in force since 1 September 2013.

Two practical notes. A local SIM needs a physical tray, so a dual-SIM phone keeps your home line in slot one. And if you land after midnight, check the counter’s hours first; the Beijing destination guide covers both airports.

How do you install an eSIM before the flight?

Do the job at home, a week before departure, on your own Wi-Fi, with the provider’s instructions open. It takes fifteen minutes and spares you the task nobody wants to attempt in an arrivals hall.

1. Confirm the phone is carrier-unlocked and supports eSIM. On iPhone this is under Settings, General, About; on Android it is usually under Network or SIM settings.
2. Fix your dates before you buy. The plan must cover every day of the stay, and trip length comes from your entry rule, which the China visa application steps explain.
3. Buy the plan and install the profile while on home Wi-Fi. Name it something you will recognize, such as China data.
4. Screenshot the QR code, the activation instructions and the support contact. If the plan fails on arrival, the provider’s site may be unreachable.
5. Leave the line switched off until you land, and never delete the profile. A deleted eSIM usually means buying a second plan.
6. Keep your home SIM active for texts. Card and app codes arrive by SMS, and the payments guide explains which setups need one.

On landing, switch the China line on, set it as the data line, enable roaming for that line only, and wait three minutes. If nothing happens, restart the phone. That fixes most first-connection failures.

Should you use your home carrier’s roaming add-on instead?

For a trip of five days or less, or any trip where you need your own number for calls and texts, roaming is hard to beat. You turn on data roaming and keep your number. You pay per day, often with a cap, and hotspot follows your plan.

Roaming also solves the verification problem, because SMS keeps working. That is worth real money if you book trains, pay by QR code or receive bank codes. The trade is daily cost, and some carriers exclude China from regional passes.

Size the trip first. A ten-day route uses more data than a city break, and the China itineraries show how much moving a normal trip involves. For a one-week visit, an eSIM for data plus a live home SIM for texts fails least often.

FAQ

Which China eSIM works best on arrival?

No single provider wins for everyone. For a short data-only trip, a fixed-data plan is enough. For heavy use with a laptop, choose a plan that states hotspot terms, such as Holafly’s 1 GB a day. If you need texts, keep your home SIM active.

Do these eSIMs come with a Chinese phone number?

No. Airalo, Holafly and Saily sell data plans, and a data plan cannot receive SMS on a Chinese number. That matters because some public Wi-Fi portals and app sign-ups send a code by text. Verify those accounts before you fly.

Can I install a China eSIM after I land?

Technically yes, if you can get online and have the QR code. In practice, airport Wi-Fi often wants a Chinese number for its login code, which is the problem you are solving. Install at home.

Will the eSIM work in Hong Kong or Macau?

Usually not on a mainland China plan. Holafly’s China page says you need a separate eSIM for Hong Kong and Taiwan. If your route crosses a border, buy a multi-destination plan and check each place is listed.

Why is a local SIM not the default choice?

It is the cheapest per gigabyte and the only option that gives you a Chinese number and SMS. The costs are time and certainty: you register in person with your passport, you queue, and some handset models cannot load a local eSIM at all.
