Can you access the internet in China as a foreign visitor?
You can get online in China as a foreign visitor, though you need to plan ahead to reach certain apps. Home to more than a billion internet users, China has the largest online population in the world — and the infrastructure to match, with high-speed 5G in almost every major city. That connectivity is driven primarily by three main network giants: China Mobile, China Unicom, and China Telecom.
However, having a good signal is only part of the equation. The real challenge is the Great Firewall, which blocks apps you might use daily, like Instagram, Google, and WhatsApp. A travel eSIM for China usually lets you access all of your favorite apps. However, you need to set it up before you travel because you’ll probably be unable to install it once you’re inside China. As an alternative, you can also use local apps like WeChat to stay in touch and Alipay for payments.
Why your usual apps stop working on Chinese networks
China’s Great Firewall works like a digital checkpoint, inspecting internet traffic and blocking access to foreign search engines, social media, and chat apps. China uses this filtering system to support domestic platforms and regulate web content. Because of this checkpoint, some apps won’t open unless you install a travel eSIM profile, set up a VPN, or arrange international data roaming before you leave.
Apps and sites that don’t load in China
When you connect to the internet in China, the Great Firewall stops many popular foreign platforms from loading. Blocked services include Google Search, Gmail, Google Maps, Google Translate, YouTube, WhatsApp, Instagram, Facebook, and X.
You can still stay connected with family and colleagues despite specific apps being restricted. Most Western apps have a Chinese counterpart you can turn to. For example, you can use WeChat instead of WhatsApp for messaging and Alipay instead of Google Pay for payments. And if you use an iPhone, built-in tools like Apple Maps and iCloud usually keep working during your trip.
How data routing affects what you can access
Several of your go-to apps won’t load on hotel Wi-Fi or with a local Chinese SIM card because both connections filter your internet traffic. However, a travel eSIM works differently. The eSIM connects to local 4G and 5G towers, but your provider routes your traffic through servers outside of China. This international path is what allows you to avoid the restrictions on overseas search engines, messaging, and social platforms while on an eSIM data plan.
Still, device configurations can vary, so test your connection as soon as your plane lands. If mobile data doesn’t kick in right away, open your cellular APN settings and check that your phone points to the correct network gateway.

To choose the best connection method for you, think about what’s most important for your trip. Do you need a Chinese phone number? Will you be sharing your connection with friends or family? Or do you simply want the most affordable way to get online for a week?
A travel eSIM: The option most visitors should start with
On a trip to China, you’ll want mobile data for keeping up with friends, posting online, or checking work emails. A travel eSIM gives you the data and keeps your usual foreign search engines, messaging, and social platforms accessible.
Keep in mind that travel eSIMs typically don’t include a local Chinese phone number. For longer stays, a local number is useful because you often need one to receive SMS verification codes for ride-hailing and food delivery apps.
How Saily’s eSIM plans for China work and how much they cost
Using a Saily eSIM data plan is one of the simplest ways to get mobile data in China, letting you set everything up online before you even pack your bags. Saily covers more than 200 destinations, so you can pick a dedicated plan for China or go with a regional plan for Asia and Oceania.
Saily’s fixed data plans for China start at US$4.49 for 1 GB over seven days. For longer visits, you can select a 30-day package with 3 GB, 5 GB, 10 GB, or 20 GB of data. If you’re on video calls for work every day or uploading travel footage, an unlimited data plan ensures you won’t run out of mobile data. Unlimited plans start at US$22.99 for five days, with options extending up to 30 days.
The Saily eSIM app keeps the setup simple — you download the app, choose a data plan, and install your eSIM profile, all without leaving your house. The data plan activates automatically upon landing, so you can get back online before you even step off the plane. You can also share your connection with fellow travelers using a personal hotspot. Additionally, to protect your browsing, the Saily eSIM app includes built-in security features like an ad blocker and web protection.
What a travel eSIM won’t do for you
Travel eSIM plans provide simple connectivity in China, but most operate as data-only services, meaning they don’t include a traditional phone number for regular calls and texts. You can keep your primary SIM active alongside your travel eSIM if your phone supports dual SIM functionality. Just keep in mind that your home carrier might charge steep rates for calls and texts abroad.
Also, an international phone line isn’t a substitute for a local Chinese number. Many domestic apps and public Wi-Fi networks send SMS verification codes that only reach local numbers. If you need local platforms during your trip, picking up a temporary physical SIM card at the airport is a practical alternative.
Buying a local SIM card in China
For vacations lasting a month or more, getting a Chinese SIM card can be a practical choice. As your trip goes on, you’ll likely want local apps for food or transport, and those apps require a Chinese number for text verification. Major networks like China Mobile, China Unicom, and China Telecom offer short- and long-term plans, though you’ll need to register with your passport when you buy the SIM card.
Where to buy a local SIM card and what the registration involves
If you decide to purchase a local SIM card, you can find carrier counters at major international airports, including Beijing Capital, Shanghai Pudong, and Guangzhou Baiyun. You’ll need your physical passport so the carrier staff can scan it. They might also photograph you to verify your identity. Registration takes roughly 15 to 30 minutes, and kiosks are typically open during primary flight hours, though operating times vary by carrier and airport. Most counters accept international credit cards, but keeping local cash on hand is always a smart backup.
What China’s major carriers charge for physical SIM cards
The cost of a local SIM card from China Mobile, China Unicom, or China Telecom depends on the point of purchase. Tourist packages sold in airports run from ¥200 (US$28.00) to ¥300 (US$42.00). But if your itinerary takes you downtown, you can visit a city center carrier store to find standard local rates ranging from ¥50 (US$7.00) to ¥150 (US$21.00). Wherever you buy your local SIM card, ask for a national data package so you are able to get online even when you cross provincial borders.
Keep in mind that standard Chinese SIM cards only deliver local data while you remain within mainland borders. If you’re going beyond the mainland, you might need a Hong Kong SIM card or an Asia-wide plan.
Using your home carrier’s roaming in China
Using international roaming typically routes your mobile traffic through servers outside mainland China. Because of this setup, your standard back-home messaging, search, and social platforms generally work as they do at home. Standard roaming packages from major carriers cost between approximately US$3.50 and US$12.00 a day, making roaming a convenient choice if you’re only staying for two or three days.
The main benefit of roaming is its simplicity — you don’t need to buy SIM cards, download apps, or set up secondary data plans. The trade-off is the higher daily cost, which varies by network operator:
Connectivity option | Estimated daily cost | Estimated weekly cost |
|---|
US carrier roaming | ~US$12.00 | ~US$84.00
|
|---|
UK carrier roaming | ~US$6.72-9.40 | ~US$47.04-65.80 |
|---|
Australian carrier roaming | ~US$3.50-7.00 | ~US$24.50-49.00 |
|---|
Saily eSIM data plan for China (1 GB/seven days) | US$0.64 | US$4.49 |
|---|
Saily eSIM for China (unlimited data/
seven days) | US$4.28 | US$29.99 |
|---|
Renting pocket Wi-Fi in China
Renting a pocket Wi-Fi device in China gives you a portable personal hotspot wherever you go in the country. You can reserve a device online to pick up on arrival, have it delivered to your hotel, or rent one at an airport kiosk.
Daily prices usually sit around US$4.00-11.00, which is great if you want to share one connection across a group. Watch out for extra costs at checkout, like refundable security deposits, delivery fees, or damage insurance.
To keep your regular search, social, and messaging tools accessible, look for a rental package that routes traffic through an international server rather than a domestic network.
Staying connected with public Wi-Fi and hotel internet
While free Wi-Fi is common in Chinese airports, hotels, and cafes, using it as an international visitor comes with a few hurdles. Most public networks require a local Chinese phone number for a verification text code, and the domestic routing leaves certain apps and websites restricted. Given those limits, it’s best to treat public and hotel Wi-Fi as a backup rather than your primary connection.
Why public Wi-Fi requires a Chinese phone number to log in
When you connect to public Wi-Fi in China, you’ll encounter an SMS verification screen. These verification texts frequently fail to reach foreign numbers. Having a local Chinese mobile number ensures you receive the access codes and ties your session to your verified identity. Think of this step as a routine identity check before you can get online.
What to keep in mind when using shared networks in China
If you’re wondering whether Chinese public Wi-Fi is safe, the short answer is that it carries the same security risks as open Wi-Fi anywhere else in the world. Casual browsing or checking map directions is usually fine, but you should avoid accessing sensitive accounts like mobile banking over open networks.
The simplest way to protect private logins is to avoid public hotspots. Relying on your personal eSIM data connection lets you skip untrusted networks altogether, while the Saily eSIM app provides added protection through built-in security features like an ad blocker and web protection.
VPNs in China: What to know before your trip
If you plan to use a local Chinese SIM card or rely on your hotel’s Wi-Fi, you’ll need a VPN to access your blocked home-country apps and websites. Download and set up your chosen VPN app before you travel because VPN download links are often blocked once you reach mainland China. Keep in mind that network filters actively monitor these connections, so performance and reliability can vary.
How much data you’ll need in China
How much mobile data you need comes down to your trip length and daily routine — whether you’re streaming videos or sticking to light browsing. You can easily estimate your gigabyte needs using an online data usage calculator. In a destination where you don’t speak the language, you might rely on your phone more — translating phrases, checking directions, hailing rides — and all of that burns through data faster than it would at home.
Which connectivity option should you choose?
Choosing between a Saily eSIM plan, a local Chinese SIM card, international roaming, or pocket Wi-Fi comes down to your itinerary and priorities. If you want to enjoy the full benefits of an eSIM — like budget-friendly data, built-in security features, and access to your everyday communication, media, and navigation apps — a Saily travel eSIM data plan makes a dependable starting point.
When comparing an eSIM vs. a physical SIM, keep in mind that a local Chinese SIM card gives you a Chinese phone number, but routes your traffic across a domestic network. Because of that domestic routing, the blocked overseas platforms you rely on back home won’t load.
For trips lasting over a month where a local phone number is essential, a physical Chinese SIM card makes practical sense. Roaming works well for short two- or three-day visits, while pocket Wi-Fi suits groups sharing one connection. Pick the option that best fits your travel style for a smooth, connected journey.
