Trip.com vs Airalo vs Alipay eSIM: which one actually works in China

They all connect to the same three Chinese networks. What separates them is where your traffic leaves the network, how much of it you get per day, and whether you can set it up before you fly.

+86 number
Local SIM only

Every option below rides on China Mobile, China Unicom or China Telecom. None of them has its own towers. So the question is never “which network is better” — it is where your data goes once it leaves the radio.

This page compares four specific things people are actually choosing between. If you want the wider provider list, the China eSIM hub covers Holafly, Nomad and Klook alongside these.

The short answer

  • One to three weeks, China only: a Trip.com China listing that names Google Maps or ChatGPT support.
  • Already on Airalo, or multi-country: it works, but the China product is now unlimited-only on China Unicom with a daily throttle.
  • Cheapest, if you read the fine print: the Alipay eSIM shop, but only listings marked Roaming IP.
  • A month or more: a local SIM with your passport, plus a roaming eSIM on the second line.
How this guide was built: Network routing, plan structure and fair-use terms from provider product pages and published policies, checked 29 October 2026. Trip.com lists several different China eSIM products with different carriers and wording; prices change constantly, so this page says check the listing rather than quoting a figure we cannot stand behind. Traveller reports are labelled as anecdotes, not tests.

Why these four behave so differently

There are two kinds of connection, and the difference is invisible on the product page.

Roaming-style eSIM

Traffic is carried back to a gateway outside the mainland — usually Hong Kong or Singapore — before it reaches the open internet. To the Chinese network you look like a visiting foreign subscriber, so Google, WhatsApp and Instagram normally load without a VPN.

Trip.com, Airalo, Klook, Yesim, Holafly and Alipay listings marked Roaming IP.

Mainland internet

You get a mainland IP. Chinese apps are fast, Google and WhatsApp are blocked, and you are back to needing a VPN that has to survive deep packet inspection on a mobile network.

A local SIM, or a cheap Alipay listing without Roaming IP.

The trade-off nobody prints on the product page: the same routing that unblocks WhatsApp can make Chinese apps slower. Didi, Amap and WeChat see a request arriving from Hong Kong or Singapore, the data takes a longer path, and some services treat overseas IPs more cautiously. Add a daily speed cap and you get the “Amap won't load and I'm stuck at the metro gate” stories.

Most straightforward

Trip.com China eSIM

The default for a single-country trip. It installs by QR code or in-app, sits in the same app as your trains and hotels, and its mainland leg runs on China Mobile (CMCC, 5G), which has the widest coverage once you leave the big cities.

Read the listing, not the category page. The one we link is a combined mainland China + Hong Kong + Macau + Taiwan product: mainland on CMCC 5G, Hong Kong on CMHK 4G, Macau on CTM, Taiwan on Chunghwa (Taiwan needs real-name verification before you land). A mainland-only Trip.com product would be a different SKU at a different price.

Terms, as published on the listing: it binds to the first device it is installed on and cannot move to another; you get up to five uninstall-and-reinstall cycles on that same device; free cancellation until 00:00 one day before the pass expires; and the pass is valid for 60 days from the booking date.

Fine, not first choice

Airalo

Easy app, straightforward top-ups. For China specifically, the product changed: its China page now lists only unlimited plans, on China Unicom as the primary network, and Airalo's own fair-use policy slows unlimited plans to 1 Mbps after 3 GB in a 24-hour window.

That is workable for maps and messages. It is not workable for a laptop on hotspot or a few videos before lunch.

Reasonable if you already use Airalo for Japan or Southeast Asia and want one app for the whole trip.

Cheapest, if you read carefully

The Alipay eSIM shop

Not Alipay's own network. It is a shopfront inside the Alipay app selling plans from several sellers. Prices are low and many are unlimited.

The two words that matter: Roaming IP. With it, or with Google / WhatsApp named in the title, you get overseas routing. Without it you get mainland internet and no WhatsApp.

You need a verified Alipay account with a linked card first. Check hotspot terms — some sellers sell the same plan with and without.

Long stays

A local China Mobile or Unicom SIM

A real +86 number and domestic routing. You need your physical passport and must apply in person at a carrier-run service hall or an airport carrier counter; nobody can register it for you. There is a limit of five SIMs per carrier per person.

Google, WhatsApp and Instagram are blocked on it. The setup long-stay visitors settle on: local SIM for Chinese apps and calls, roaming eSIM on the second line for everything else.

Other options worth knowing

Do you actually need a Chinese number?

For a short city trip, usually not. Alipay registers with a foreign number, Didi runs inside Alipay or accepts foreign numbers, 12306 supports passport registration with an overseas number, and Amap works for navigation without an account.

Where a +86 number still matters: Meituan and Dianping, bike-share apps, food delivery where the rider calls you, and public Wi-Fi that sends its login code by SMS.

Set it up at home, in this order

  1. Check the phone. It must be carrier-unlocked and support eSIM. Mainland China iPhones mostly do not, and cannot install a foreign eSIM while inside the mainland.
  2. Set up Alipay and WeChat with your home number, including passport verification and card linking. You cannot buy an Alipay eSIM without this.
  3. Buy the eSIM before you fly. Install it on Wi-Fi at home if you want to test that it loads, and leave the line switched off. Trip.com's own instructions suggest installing after arrival instead, so the usage period does not start early — either works if you keep the line off until you land.
  4. On landing: set the eSIM as the mobile-data line, enable roaming for the eSIM only, and turn off mobile data switching so your home plan is never used.
  5. Keep your home line on for SMS with its data roaming off — bank and Alipay codes arrive there, not on the eSIM.
  6. Install a VPN anyway. The eSIM only changes routing on mobile data; hotel Wi-Fi is mainland internet. Our VPN guide covers that case.

Troubleshooting the four things that go wrong

No data at all after landing.

Confirm data roaming is on for the eSIM line, then toggle airplane mode for ten seconds. If it still will not connect, check the APN; the Trip.com mainland listing publishes cmhk. Restart after changing it.

Didi, Amap or WeChat are slow but WhatsApp is fine.

Overseas routing, a daily cap, or both. Check today's usage against the plan threshold, try manually selecting another network in carrier settings, and download offline maps for your cities.

Western apps stopped working on hotel Wi-Fi.

That is expected. Hotel, cafe and airport Wi-Fi is mainland internet. Turn Wi-Fi off to return to the eSIM routing.

SMS codes are not arriving.

Most travel eSIMs are data-only, so the code goes to your home number instead. Keep the home line enabled with data roaming off, and check before you fly whether your carrier blocks international SMS while roaming. Some China products do bundle a Hong Kong number for calls and SMS — the inclusions list on your listing will say.

What traveller threads are saying

Late-October threads on the China travel subreddits keep circling the same three points: Airalo drew the loudest warnings about sluggish Didi and Amap; Trip.com drew the most positive mentions, usually followed by someone asking which of its several China listings actually unblocks Google; and the “eSIM plus VPN versus local SIM” debate ended where it always does — eSIM for short trips, local SIM for long stays.

These are anecdotes from other travellers, not tests. Networks vary by city and by hour, and we have not reproduced them.

FAQ

Which China eSIM keeps WhatsApp and Google working?

One that routes your data outside mainland China before it reaches the internet, usually via Hong Kong or Singapore. Check the listing for a line naming Google, WhatsApp or ChatGPT support, or for the words Roaming IP in an Alipay listing. A local China Mobile or Unicom SIM does not do this.

Do I still need a VPN with a travel eSIM?

Not on mobile data if the eSIM routes abroad. You still need one for hotel, cafe and airport Wi-Fi, which are mainland internet, and for any laptop work. Our VPN guide covers what actually holds up.

Why are Didi, Amap and WeChat slow while WhatsApp is fine?

Because the traffic is leaving China and coming back. Chinese apps see an overseas IP, take a longer path, and some treat it more cautiously. A daily speed cap makes it worse. Check how much data you have used today, download offline maps, or add a cheap local SIM for Chinese apps.

Is a 30-day unlimited plan really unlimited?

No. Airalo throttles unlimited plans to 1 Mbps after 3 GB in a 24-hour period, and other providers cap similarly. That is enough for maps and messages but not for video or a laptop on hotspot. Read the fair-use policy, not the plan name.

Can a foreigner buy a China Mobile SIM at the airport?

Yes, in person with your physical passport at a carrier-run service hall or an airport carrier counter. Registration is real-name and usually includes a photo check. Nobody can register a SIM on your behalf, and there is a limit of five SIMs per carrier per person.

Do iPhones bought in mainland China work with travel eSIMs?

Mostly no. Apple lists only a few mainland China iPhone models with eSIM hardware, and those cannot install a non-mainland carrier eSIM while you are inside mainland China. Use a physical roaming SIM or pocket Wi-Fi instead.

Research notes & sources

No operator paid for inclusion. Some booking links earn a commission at no extra cost to the reader. Details change — confirm with the official source before you travel.

Buy this before you fly

One eSIM, installed on home Wi-Fi

Whatever you pick, install and test it before departure. Arriving without working data means relying on airport Wi-Fi you may not be able to open.
