If you're traveling to China, getting internet isn't as straightforward as in other destinations. Here, simply turning on your data isn't enough: the country filters a large part of the internet, and many of the apps you use daily—Google, WhatsApp, Instagram—simply won't load. In this guide, I'll tell you about all the ways to get internet in China as a tourist (your carrier's roaming, hotel Wi-Fi, a local Chinese SIM, and a travel eSIM), what gets blocked and what doesn't, and how to get your phone working normally so that your traffic leaves the country and you can continue using your usual apps without a struggle.
Internet in China: The Quick Answer
In China, the most reliable way for tourists to get internet is a travel eSIM that routes your data outside the country, allowing you to use Google, WhatsApp, and Instagram without a VPN. Roaming also bypasses the firewall but is expensive; hotel Wi-Fi and local Chinese SIMs are censored.
China's peculiarity is that the problem isn't coverage—there's excellent 4G and 5G everywhere—but censorship. The so-called Great Firewall blocks most Western services, so you might have five bars of signal and still not be able to open your Gmail or send a WhatsApp message. Therefore, before choosing how to connect, it's wise to understand what is filtered and what isn't, because each option behaves very differently against that wall.
Quick rule: if your data leaves China (roaming or eSIM that routes data out), your apps work; if your data travels through the Chinese network (hotel Wi-Fi, local SIM), it's filtered and you'll need a VPN. Everything else—price, convenience, and procedures—revolves around that single idea.
Why China is Different: The Great Firewall
The Great Firewall is the internet censorship system operated by the Chinese state. It doesn't block just one or two specific websites; it filters entire categories of services using various combined techniques—DNS poisoning, IP address blocking, deep packet inspection, and connection cutting. The result is that when you try to open a Western app, the request either never reaches its destination or is cut off halfway.
What's important for you as a traveler is to understand that it's not a malfunction of your mobile or your contract: it's the country itself that decides what passes and what doesn't. And the filter is applied depending on where your data travels. If your connection travels through Chinese infrastructure (your hotel's Wi-Fi, a SIM purchased there), you are inside the wall and subject to censorship. If your connection, however, leaves China and reaches the internet through another country, the wall has nothing to filter. This is the key that explains why some options let you use your apps and others don't, and why the solution doesn't always involve installing a VPN, which is also becoming increasingly unreliable in 2026.
Which Apps are Blocked (and Which Aren't)
The list of blocked items is long and covers exactly what a Western tourist uses most: searching on Google, opening Maps, sending a WhatsApp message, or uploading a photo to Instagram. This table summarizes the most common services, whether they are blocked on the Chinese network, and whether they work again when your data leaves the country (e.g., with an eSIM that routes data out):
| App or Service | Blocked on Chinese network? | Works if your data leaves China? |
|---|---|---|
| Google (Search, Gmail, Maps, Drive) | Yes | Yes |
| YouTube | Yes | Yes |
| Yes | Yes | |
| Yes | Yes | |
| Facebook and Messenger | Yes | Yes |
| X (Twitter) | Yes | Yes |
| Telegram and Signal | Yes | Yes |
| WeChat and Alipay | No (they are Chinese) | Yes |
| Bing and Apple iMessage | Work with nuances | Yes |
As you can see, practically the entire Google and Meta ecosystem falls on the blocked side. What does work inside China are local apps (WeChat for chatting and payments, Alipay, Baidu as a search engine, Amap or Baidu maps), which are very useful on the ground but don't replace your usual accounts. That's why the goal isn't to get by with Chinese apps, but to get your own apps to load again.
Your Operator's Roaming: Works, but Expensive
The first option, and the most convenient of all because you don't have to install anything, is to leave roaming activated and use your Spanish plan in China. And here's a useful surprise: when you're roaming, your data usually routes back to your operator's network in Spain before going out to the internet. Since that exit happens outside China, the Great Firewall doesn't intervene, and your apps—WhatsApp, Google, Instagram—tend to work normally.
The problem is the price. China is outside the European Union, so "roaming like at home" doesn't apply: rates are expensive. Without a specific travel add-on, browsing can cost a fortune for little usage; with an add-on, we're talking about €10-15 per day, which adds up significantly on a two-week trip. It's the option to pay for convenience, valid if you're going for two or three days, but difficult to justify for a long stay. Before choosing this route, it's worth checking how much the bill goes up in how much international roaming costs and carefully comparing it with the alternative in eSIM vs. roaming.
Hotel Wi-Fi: Free but Censored
Hotel, airport, or cafe Wi-Fi is free and usually has good speed, but it has an insurmountable underlying problem: it runs through China's internet infrastructure. The moment you connect to that local network, your traffic enters the Great Firewall completely and is filtered again. It doesn't matter if it's a five-star hotel: Google, WhatsApp, and Instagram will still not load.
It's a nuance that catches many people by surprise. A traveler who arrives with roaming or an eSIM and sees that everything is working, connects to the hotel Wi-Fi to save data... and suddenly their apps stop responding. It's not that the Wi-Fi is failing: it's that it has put you back behind the wall. To use your usual services over Wi-Fi, you would need a reliable VPN, something increasingly difficult in China. My practical advice: use hotel Wi-Fi only for what works there (Chinese websites, local information) and reserve your mobile data routed outside for everything else. If you were considering a pocket router, in eSIM vs. pocket Wi-Fi I break down both ideas in detail.
The Local Chinese SIM: Cheap, Requires Procedure, and Filtered
Buying a local SIM card from China Mobile, China Unicom, or China Telecom upon arrival sounds cheap, and in terms of data, it is. But it has two serious drawbacks for a tourist. The first is the procedure: China applies real-name registration, so you have to present your passport to activate the line, fill out forms, and sometimes struggle with the language at a carrier store. It's not something you can resolve in two minutes right after landing.
The second, and most important, is that a local Chinese SIM connects you to the internet within China. That is, your traffic travels through the national network and is subject to the Great Firewall just like hotel Wi-Fi: Google, WhatsApp, and Instagram are blocked. To use them, you would need a VPN, with all the uncertainty that entails today. So, the local SIM gives you abundant and cheap data, but it leaves you on the censored side of the wall, which is exactly what a traveler wants to avoid. If you want to see the complete face-off between this option and the digital one, I break it down in eSIM vs. local SIM.
The Travel eSIM: Why It's Recommended
The travel eSIM combines the best of the previous options and eliminates their drawbacks. Technically, it's a digital SIM that's already integrated into your mobile and that you activate with a QR code, without cards or procedures. But what makes it special for China is how it routes your data: the eSIM hooks into a Chinese antenna for signal, but your connection goes out to the internet through a foreign network—in Hong Kong, Singapore, or Japan, depending on the provider—before reaching the web. Your traffic never passes through the Chinese internet that the Great Firewall filters.
In other words: with a well-chosen travel eSIM, your phone is physically in Beijing, but your data "appears" in Singapore. The wall has nothing to filter, so WhatsApp, Google, Maps, and Instagram work as they would at home, without installing any VPN.
Added to this is that you keep your Spanish number active with Dual SIM (for bank SMS and calls), you install it from home in minutes, and it costs much less than roaming. It is, by far, the cleanest way for a tourist. If this is the first time you've heard of this format, it will be helpful to read what an eSIM is to understand how it works internally.
Comparison of All Options
With all four ways to connect placed side by side, the decision becomes much clearer. This table summarizes the approximate price, whether you experience censorship, whether you need a VPN, and how convenient each method is for a normal tourist trip:
| Option | Approx. Price | Apps Blocked? | Needs VPN? | Convenience |
|---|---|---|---|---|
| Your operator's roaming | High (€10-15/day or more) | No (traffic goes out to Spain) | Usually not needed | High, but expensive |
| Hotel or café Wi-Fi | Free | Yes, censored | Yes (and unreliable) | Medium |
| Local Chinese SIM | Low | Yes, censored | Yes | Low (passport and procedure) |
| Travel eSIM that routes outside | Medium-low | No (traffic goes out) | No | High |
The takeaway is straightforward: only two options free you from the wall without a VPN, roaming and eSIM, and of those two, the eSIM is much cheaper. Wi-Fi and local SIMs are useful for specific things, but they leave you at the mercy of censorship. Therefore, for most travelers, the winning combination is a travel eSIM for your daily data and hotel Wi-Fi only as backup for what does work there.
Coverage and Data in Beijing, Shanghai, and Xi'an
The good news is that in major Chinese cities, coverage isn't an issue: it's among the best in the world. In Beijing, you'll have strong 4G and 5G throughout the city, including tourist spots like the Forbidden City, Tiananmen Square, and the Temple of Heaven. In Shanghai, connectivity is equally good in the Bund, Pudong, the French Concession, or Yu Garden. And in Xi'an, both in the historic center and on the city wall, as well as in the Terracotta Warriors area, the signal is solid. A travel eSIM relies on these same local networks, so the speed is like that of any Chinese local, with the difference that your data leaves the country.
How much data do you need? For normal tourist use—maps, messaging, some social media, and looking up places—plan for about 500 MB to 1 GB per day. For a typical trip of 7 to 14 days, a 10 to 20 GB plan is the sweet spot; if you'll be streaming a lot of video or tethering your laptop, move up a tier. In the eSIM for China guide, I go into more detail about plans and consumption.
How to Get Everything Ready Before You Fly
Here's the most important advice in this entire guide, and the one most people skip: buy and install your eSIM before landing in China. It sounds obvious, but there's a trick. Once you're inside the country, app stores and many websites for activating services are blocked, so an eSIM you haven't prepared might be one you can't finish setting up. Install it at home using your Wi-Fi, calmly, and turn it on when you get off the plane, already connected.
The process is simple: choose your plan for China based on the number of days and GB, receive the QR code by email in minutes, scan it from your phone's settings, and leave the eSIM installed (without activating it yet). Upon landing, activate its data, and if you use Dual SIM, turn off data roaming for your Spanish line to avoid extra charges. With that, you'll leave the airport with Google Maps open and WhatsApp working. That small act of preparing everything from home is the difference between enjoying a connected trip or being stuck behind the wall looking for Wi-Fi that won't help you either. You can get it sorted today with the eSIM for China.
Frequently Asked Questions
Does WhatsApp work in China?
On the Chinese network, it's blocked, so with hotel Wi-Fi or a local SIM, it won't load. But if your data leaves the country—with roaming or a travel eSIM that routes data out—WhatsApp works completely normally, without the need for a VPN, for chatting, calling, and sending audio messages.
Does Google (Gmail and Maps) work in China?
The entire Google ecosystem is blocked inside China: search, Gmail, Maps, Drive, and YouTube. It works again as soon as your connection leaves the country. With an eSIM that routes data out, you open Google Maps and your email just like in Spain, without tricks or complicated configurations.
Do I need a VPN to use the internet in China?
Only if your data travels through the Chinese network (hotel Wi-Fi or local SIM). If you use roaming or a travel eSIM that routes traffic outside, you don't need a VPN. Additionally, by 2026, many consumer VPNs have stopped working in the country, so it's not advisable to rely on them.
Can I install the eSIM once I'm already in China?
It's best not to risk it. Inside China, app stores and several activation websites are blocked, so you might not be able to download or configure anything. The strong recommendation is to buy and install the eSIM from home, using your Wi-Fi, and turn it on upon landing, already ready.
Will hotel Wi-Fi let me use Instagram?
No. Hotel, airport, or cafe Wi-Fi runs through Chinese infrastructure and is subject to censorship, so Instagram and other Western apps will remain blocked. Use it only for services that do work in China and rely on your mobile data routed outside for everything else.
How much data do I need for a week in China?
For normal tourist use, estimate between 500 MB and 1 GB per day, which means about 5 to 10 GB for a week. If you're going to use a lot of video, constantly use maps, or share your connection with a laptop, it's better to go for 10-20 GB to be safe.
Is a local Chinese SIM useful for using my usual apps?
For abundant and cheap data, yes; for your Western apps, no. A local SIM connects you within China, so Google, WhatsApp, and Instagram are blocked unless you use a VPN. Added to that is the passport procedure for real-name registration. For a tourist, it rarely pays off.
Does my operator's roaming work in China?
Yes, and it usually bypasses censorship because your data goes out to the internet through your Spanish network. The problem is the price: China is an expensive zone, and without a travel add-on, the bill can skyrocket. It works well for two or three days; for longer stays, an eSIM is much more cost-effective.
Conclusión
Having internet in China has a nuance that doesn't exist in other destinations: signal isn't enough, you have to bypass the Great Firewall. Of the four ways to connect, hotel Wi-Fi and local SIMs leave you censored; roaming frees you from the wall but at a high price; and a travel eSIM that routes your data out gives you the best of everything: your usual apps working without a VPN, your Spanish number active with Dual SIM, and a very reasonable cost. Get it ready from home and land connected, with Maps, Gmail, and WhatsApp ready from the first minute. Once you've decided, take a look at the eSIM for China and forget about the wall for the entire trip.
