How can I get internet if I don't have an eSIM?
Without an eSIM, you have four real ways to connect in China: activating international roaming with your usual carrier, buying a physical Chinese SIM card upon arrival, renting a portable WiFi (pocket WiFi), or relying on free hotel and cafe WiFi. Each has a different cost in terms of money, time, and patience.
None of the four is bad in itself, but China has a peculiarity that makes your choice of method matter more than in any other destination: the Great Firewall blocks services you probably use every day, and that completely changes which solution is best for you. Before deciding, it's worth understanding this starting point.
How do I get internet in China?
Having signal in China is not the same as having access to "your" internet. The Chinese government filters traffic to foreign servers through a censorship system popularly known as the Great Firewall. This means that, no matter what connection you have—roaming, local SIM, portable WiFi, or hotel WiFi—many of the tools you use daily to communicate or find your way simply won't load.
Commonly blocked services include Google in all its versions (Search, Gmail, Maps, Drive), WhatsApp, Instagram, Facebook, X (formerly Twitter), and YouTube. In their place, China has its own ecosystem: WeChat for messaging and payments, Baidu Maps for location, and Alipay for almost any purchase, from a coffee to a subway ticket.
In China, having a full signal on your phone guarantees nothing: you can see four bars and still not be able to open WhatsApp to say you've arrived safely at the hotel.
The practical way to solve this is a VPN (virtual private network) that encrypts your traffic and routes it out of the country before the filter detects it. Without a working VPN, it doesn't matter what kind of internet connection you've subscribed to: you still won't be able to use your usual apps. And here's the fact that many travelers discover too late: app stores (App Store, Google Play) are also filtered within China, so if you try to download your VPN after landing, you probably won't be able to. Download and install it while you're still in your home country, before boarding.
| Service you normally use | Works without VPN in China? | What they use instead |
|---|---|---|
| Google (Search, Gmail, Maps, Drive) | No | Baidu, local search engines |
| WhatsApp / Facebook Messenger | No | |
| Instagram / Facebook / X | No | Weibo, WeChat Moments |
| YouTube / Netflix | No | Youku, iQIYI |
| Card/app payments from your country | Limited | Alipay, WeChat Pay |
| Calls and SMS over Wi-Fi (iMessage, native apps) | Yes, usually | — |
International roaming: the simplest option (and its fine print)
Activating roaming with your usual carrier is, on paper, the option with the least friction: you don't buy anything new, you don't change your number, your phone works as soon as you land. For a short or business trip where you prioritize simplicity, it can make sense.
The problem appears in the fine print. Many roaming plans charge per megabyte consumed outside your base package, and that charge isn't visible until the following month's bill arrives. Other plans do include data packages for travel, but it's worth checking two things before you leave: if China is actually included in the coverage (not all "international" plans cover Asia) and what the data limit is before the price per MB skyrockets.
Another practical limitation: roaming depends on your carrier having an agreement with a Chinese network, and the quality of that visited network is not always the best available in the city you're in. If you want to avoid surprises, comparing roaming with other alternatives—as we explain in our eSIM vs. roaming comparison—helps you decide based on facts, not habit.
Buying a physical Chinese SIM upon arrival
The second classic option is to buy a local SIM card as soon as you land, at the counters of carriers like China Mobile, China Unicom, or China Telecom, which are usually found in the international airports of Beijing, Shanghai, or Guangzhou. It's a well-known solution and generally offers good coverage because you're directly using the local network.
It has three frictions that are worth anticipating. First, China requires real-name registration: you'll need to show your passport and, in some cases, provide your biometric data (photo or fingerprint) at the counter, a process that can take a while if there's a queue. Second, your home cell number will be out of service while you use the Chinese SIM, so anyone who calls or texts your usual number won't be able to reach you. Third, when you leave the country, that SIM becomes useless and you usually discard it, so if your next destination isn't China, you start the process all over again.
For those traveling with more than one device or who only need to keep their original number active for WhatsApp, this friction is precisely what led many travelers to compare physical SIMs with eSIMs: you can read that detailed comparison between eSIM and physical SIM if you're interested in why.
Renting a portable WiFi (pocket WiFi)
Portable WiFi—also called pocket WiFi or MiFi—is a device about the size of a thick credit card that creates its own WiFi network and shares it with multiple devices at once: your phone, your tablet, your laptop, and the phone of anyone traveling with you, all connected to the same device.
It's usually reserved before the trip and picked up at an airport counter or received by mail at your home, and returned at the end of the trip (or sent back by mail with a prepaid envelope). It's a good option for groups or families, as it splits the cost of data among several devices instead of paying for a solution per person.
Its drawbacks: it's one more device to carry and not lose, it has its own battery that drains with continuous use, and if you move away from whoever is carrying it in their backpack, you lose signal. It also adds a logistical step—picking up and returning the equipment—that the other options don't have.
Free WiFi in hotels, airports, and cafes: when it works
Free WiFi seems like the most obvious and economical option, but in China it has peculiarities that are not always true outside the country. Many hotels require you to register your room number or even your passport before giving you the password, so it's not always "connect and go" as soon as you arrive. Large international chains tend to be more agile with this than boutique or local hotels.
Outside the hotel, public WiFi in cafes, shopping centers, or airports almost always requires a Chinese mobile number to receive a verification code via SMS, something you obviously don't have if you've just arrived. This makes "free" WiFi an unreliable option as a primary plan, and more reasonable as a complement once you've sorted out your mobile connection through another means.
The practical consequence: relying solely on free WiFi leaves you without internet on the way from the airport to the hotel, on the subway, walking down the street, or calling a ride on an app—precisely when you need it most in a country where you don't speak the language.
Comparison: all 4 non-eSIM options, side by side
Before deciding, this table summarizes what we reviewed in the previous sections so you can compare at a glance.
| Option | Works as soon as you land | Requires on-site process | Keeps your home number active | Ideal for |
|---|---|---|---|---|
| International roaming | Yes | No | Yes | Short trips, those who want simplicity |
| Physical Chinese SIM | No (requires queueing and registration) | Yes (passport, sometimes biometrics) | No, while in use | Long stays in a single country |
| Portable WiFi | No (reservation + pickup/return) | Yes (pick up and return device) | Yes | Groups or families with multiple devices |
| Free WiFi (hotel/cafe) | Depends (prior registration) | Variable | Yes | Complement, not primary plan |
What SIM card can I use in China?
If you choose the physical SIM route, in China you can use cards from the three major state-owned operators: China Mobile (the network with the most coverage in rural areas), China Unicom (good coverage-to-price ratio in cities), and China Telecom. All three sell tourist packages designed for visitors, valid for days or weeks with included data, available at the counters of major international airports.
One overlooked point: your phone must be unlocked (not carrier-locked) to accept a Chinese SIM, and it must be compatible with the frequency bands used by Chinese networks. If your phone is locked to a single carrier from your home country, no local SIM will work until you unlock it, something best resolved before traveling, not at the airport counter.
How to get "unlimited" internet in China?
The word "unlimited" in data plans—whether roaming, local SIM, or any other type—almost always comes with a fair use policy behind it: after a certain consumption (for example, after using several gigabytes at maximum speed in a single day), the operator reduces your connection speed even if it technically "doesn't cut out." This is standard industry practice, not an exception in China, and it's worth reading the plan's terms and conditions instead of just relying on the word "unlimited" in the advertisement.
In practice, for most trips—checking maps, sending messages, uploading photos, using translation apps—a data package of several gigabytes per week is usually sufficient without needing to look for "unlimited" plans. If your travel plan includes working online, making long video calls, or streaming content, then it's wise to calculate your actual consumption before choosing the package, instead of trusting a marketing label.
The eSIM: the option almost nobody searches for by name
If you've made it this far looking for how to get internet in China "without an eSIM," it's probably because you weren't sure what an eSIM was or thought it was complicated to set up. It's worth learning about it, even if just to rule it out with real information: it is, simply put, a digital SIM card integrated into your own phone, which you activate by scanning a QR code before traveling, without going to any counter or queuing upon arrival.
Compared to the four options we've seen, it solves the friction of each: it doesn't depend on your home carrier's roaming agreement, it doesn't require you to register your passport at a Chinese counter, it's not an extra device to carry or return, and it doesn't depend on a cafe or hotel giving you a password. It keeps your WhatsApp number active with your usual physical SIM in the second slot of your phone, while data browsing goes through the eSIM. Most mid-range and high-end phones from recent years are compatible; you can check the complete list in our eSIM compatible phones guide.
If you've never installed one, the process is simpler than it seems and takes only a couple of minutes by following a QR code; we explain it step-by-step in how to install an eSIM, and if you want to understand the concept from scratch, start with what is an eSIM. For China specifically, the PuraSIM eSIM for China activates in approximately 1 minute, gives you 180 days from purchase to activate it when you decide, and if something doesn't work, you have 24/7 support in all languages via email and WhatsApp—the same WhatsApp you'll continue to use from your usual physical SIM.
Frequently asked questions
How can I get internet if I don't have an eSIM?
With international roaming from your carrier, by buying a physical Chinese SIM upon arrival, by renting a portable WiFi, or by using free hotel and cafe WiFi. Each option has a different balance of cost, convenience, and procedures.
How do I get internet in China?
First, you choose how you'll connect (roaming, local SIM, portable WiFi, eSIM, or free WiFi), and then you install a VPN before traveling, because without it you won't be able to use Google, WhatsApp, Instagram, or YouTube within the country, regardless of the type of connection you've arranged.
How do I get unlimited internet in China?
Check the fair use policy of any plan that claims "unlimited": almost all of them reduce speed after a certain daily consumption. For most trips, a package of several gigabytes per week is usually sufficient without needing to look for unlimited plans.
What SIM card can I use in China?
Physical cards from China Mobile, China Unicom, or China Telecom, purchased upon arrival with your passport, or an eSIM activated before traveling if your phone is compatible. In both cases, the phone must be unlocked from its carrier.
Do I need a VPN if I travel with an eSIM to China?
Yes. The VPN and the type of internet connection are different things: the eSIM (or any other connection) gives you internet access, but the Great Firewall still filters services like Google or WhatsApp unless you use a VPN, no matter how you connect.
Is free hotel WiFi in China sufficient for the whole trip?
It serves as a supplement within the hotel, but not as a primary plan: many require registration with a passport or room number, and it doesn't cover you on your commute, on the subway, or on the street, which is where connection is most needed in a country with a different language and alphabet.
Can I continue using my WhatsApp number in China?
Yes, as long as your phone has an active data connection by some means and you have installed a VPN before traveling, as WhatsApp is blocked by the Great Firewall without it. With an eSIM, your physical SIM with your original number can remain in your phone without being deactivated.
How long does a portable WiFi battery last in China?
It varies depending on the model and usage, but it drains with continuous use, so it's advisable to carry a portable charger if you're going to be out of the hotel all day.
Conclusion: what to choose based on your trip
If your priority is simplicity and you don't mind the price of roaming, activate it from home. If you're staying for weeks in China and need the best possible local coverage, a physical SIM outweighs the airport process. If you're traveling in a group and want to split the cost of data among several devices, portable WiFi makes sense. And if you're looking to activate your connection before leaving home, without queues, without registering your passport at a counter, and without losing your WhatsApp number while browsing, the eSIM solves all four frictions at once.
Whatever you choose, don't leave it until the last minute: install your VPN before you travel, because once in China you won't be able to download it.
