Can you use Google, LINE, Facebook and Instagram in China, and which connection should you pick
An app-by-app table for China (Google, LINE, Facebook, Instagram, YouTube, WhatsApp) on hotel WiFi, a local SIM or a roaming-based travel eSIM, then how to choose between an eSIM, a Chinese SIM, Thai roaming and pocket WiFi.
Risposta rapida
- In China, foreign apps such as Google, Facebook, Instagram, YouTube, WhatsApp and sometimes LINE are commonly blocked or unreliable on local networks (a Chinese SIM or hotel WiFi). Some roaming-based travel eSIM plans route traffic through a foreign network, so these apps often open, but it depends on the plan and nobody can guarantee it, so read the plan page.
- Is an eSIM a good idea for China? For people who want to keep using their usual Thai and foreign apps, a roaming-based eSIM is often the most convenient since you can install it ahead and skip Chinese SIM registration. If you need a Chinese number or local services, a Chinese SIM may matter more.
SIM or eSIM for China: the overview first
The question "SIM or eSIM for China" really has two layers. The first is whether your phone supports eSIM. The second is which route your data takes to the internet, because that decides whether Google, LINE or Instagram open, not whether the plan is a plastic SIM or an eSIM.
China's local networks filter some foreign content, so a Chinese SIM and hotel WiFi commonly hit the same limits. Some travel plans work as roaming, meaning data travels back out through a network outside China, so the result differs, but the technical details and stability depend on each plan and can change over time.
App-by-app table: Google, LINE, Facebook, Instagram, YouTube, WhatsApp
The table shows general tendencies, not guarantees. Real status changes, so test the apps you depend on before you fly, and remember that reaching an app is a separate matter from local law or each app's own terms.
| App | Hotel WiFi / Chinese SIM | Roaming-based foreign eSIM |
|---|---|---|
| Google (Search, Maps, Gmail) | Commonly blocked or unreliable | Often opens, depends on the plan |
| LINE | Behaviour varies; messages may be slow or fail | More likely to work normally, not guaranteed |
| Facebook / Messenger | Commonly blocked | Often opens, depends on the plan |
| Commonly blocked | Often opens, depends on the plan | |
| YouTube | Commonly blocked | Often opens; video uses a lot of data |
| Messages or calls may fail or be unreliable | Often works, depends on the plan |
General tendencies, not guarantees
Does Google work: Google in China and with a China eSIM
Google services such as Search, Maps, Gmail and Drive are commonly unavailable on local networks. With a roaming-based eSIM the result often differs, but nothing is guaranteed and some services can still be slow. The safe approach is not to depend on Google alone.
- Download offline maps and save place names in Chinese before you fly. See our offline maps guide.
- Install a translation app and a map app that suit your use in China, and create accounts before you leave, following each app's own terms.
- Screenshot your hotel address in Chinese in case the connection drops.
LINE and WhatsApp: do they work in China
For Thai travellers LINE matters most, but its behaviour in China is not constant. At times plain messages work while photos, video or calls are slow, and at other times problems are bigger. WhatsApp is similar, so do not rely on a single app for important things like pickups or contacting family.
- Set up a backup channel such as SMS or a normal call with family, but check your home SIM's roaming terms first.
- Share your hotel address and itinerary with someone at home before you fly, rather than hoping messages will always go through.
- If you need OTP codes from a Thai bank, plan ahead before flying. Read our SMS OTP abroad guide.
Facebook, Instagram and YouTube: do they work in China
These foreign social and video platforms are the group most commonly unreachable on local networks. If you plan to post during the trip, shoot and save first, then upload when you can connect or after leaving China. With a roaming-based eSIM they often open, but streaming video uses a lot of data, so turn on data-saving options and use accommodation WiFi for big files.
Is an eSIM good for China: pros and cons of each option
| Opzione | Adatto a | Attenzione a |
|---|---|---|
| Travel eSIM (roaming-based) | People who want to keep using Thai and foreign apps, install ahead and avoid Chinese SIM registration | Phone must support eSIM and be unlocked; data only, no phone number; app behaviour depends on the plan |
| Chinese SIM / local China eSIM | People who need a Chinese number or local services | May involve identity registration, and foreign apps are commonly limited as on local WiFi |
| Thai roaming | People who need their usual number for calls and OTP | Check terms and charges with your operator; bill-shock risk if not set up carefully |
| WiFi tascabile | Groups sharing one connection | Pickup and return, charging and one more device to carry; app behaviour depends on the provider |
China eSIM or roaming: how to choose
Roaming on your main SIM keeps your usual number and lets you receive SMS and OTP, but prices and terms vary widely by operator, so check your own roaming offer and set usage limits. A travel eSIM has no phone number, but you avoid surprise bills because you buy a plan in advance.
- If you need OTP or calls on your usual number, keep your main SIM and switch roaming on only as needed, using the eSIM for data.
- Read more in our guides on eSIM versus roaming and avoiding roaming bill shock.
China eSIM or pocket WiFi, and eSIM or local SIM
Pocket WiFi wins when several people share one connection, but you must plan pickup and return and carry another device. An eSIM is simpler for solo travellers or couples whose phones both support it. A local SIM suits long stays or when you need a Chinese number, but accept the registration steps and that foreign apps are commonly limited as on other local networks.
Steps to choose and prepare before flying to China
- 1Check your phoneUse the device checker to see whether your phone supports eSIM and is unlocked. Some market variants differ.
- 2List the apps you truly needSplit into "must have" (contacting home, maps, banking) and "nice to have" (social, video), and choose the connection that covers the first group first.
- 3Read the plan pageCheck coverage, validity and any app notes, and check the live price before you buy.
- 4Installa prima di volareInstall the eSIM while you have WiFi and switch it on at your destination. See our install guide.
- 5Test apps and prepare backupsOpen your key apps, download offline maps and translation packs, and note your hotel address in Chinese.

FAQ
Should I use a SIM or an eSIM in China?+

Does Google work with a China eSIM, and in China generally?+
On local networks Google is commonly unavailable. Some roaming-based eSIM plans often open it, but it is not guaranteed and can change, so keep offline maps as a backup.

Behaviour is not constant. At times messages work while photos or calls are slow. Test before you fly and set a backup channel with family.
Do Facebook and Instagram work with a China eSIM or in China?+
On local networks they are commonly unreachable. A roaming-based eSIM may open them depending on the plan. If unsure, save photos and post later on WiFi outside China.
Does YouTube work with a China eSIM?+
It depends on the plan and the network your data travels through. If it opens, video uses a lot of data, so use the data calculator and lower video quality.
