You'll use your phone for maps, translation, mobile payments, train bookings and contacting hotels. Arrive without a connection and even simple tasks can become frustrating. The good news is that you have three main options: a travel eSIM, international roaming through your home provider, or a local Chinese SIM card. Each has advantages, and the right choice depends on how long you're staying, whether you need a Chinese phone number, and which services you want to access. **Quick answer: What's the best way to get internet in China as a tourist?** For most short trips, a travel eSIM that explicitly covers mainland China or a suitable international roaming plan is the easiest option. A local Chinese SIM is worth considering for longer stays or when you need a mainland Chinese phone number. Check your phone's compatibility, data allowance and the plan's connectivity arrangements before departure. *Part of our China travel guide for foreigners.* ## eSIM vs roaming vs local SIM: quick comparison | Option | Best for | Main advantage | Main drawback | | --------------------- | ------------------------------------------- | ------------------------------------------------ | ---------------------------------------------------------------------------- | | Travel eSIM | Short and medium trips | Set it up before departure; no physical SIM swap | Requires a compatible, unlocked phone; plan features vary | | International roaming | Convenience and keeping your number | Uses your existing mobile account and number | Can be expensive without a suitable travel package | | Local Chinese SIM | Longer stays or a need for a Chinese number | Local number and operator-specific packages | Passport registration, in-person application and device compatibility checks | Remember that mobile data and a Chinese phone number are different things. A data-only travel eSIM can give you internet access without providing a Chinese number for calls, texts or local verification. --- ## Option 1: Travel eSIM An eSIM is a digital SIM profile that you install on a compatible phone. Depending on the device and carrier, you can use it alongside your existing SIM rather than physically replacing your home SIM card. The main advantage is convenience. You can usually purchase and install a travel eSIM before leaving home, then activate or enable it according to the provider's instructions when you're ready to use it. ### What to check before you buy Before purchasing a plan, check the following: - **Phone compatibility:** Confirm that your exact phone model and regional variant support eSIM. Availability differs between devices and markets. - **Carrier lock:** Your phone generally needs to be unlocked to use a travel eSIM from another provider. - **Mainland China coverage:** Check that mainland China is explicitly included. A plan covering Hong Kong or Macau does not automatically cover mainland China. - **Validity and activation:** Find out when the plan's validity period begins. It may start at installation, activation or first connection, depending on the provider. - **Data allowance:** Check the total data included, daily limits, speed restrictions and what happens when the allowance is used up. - **Hotspot support:** If you want to share your connection with a laptop or another phone, confirm that tethering is permitted. - **Network and connectivity arrangements:** Check the provider's explanation of network partners, routing and access to the services you need. ### Why routing matters in China Not all travel eSIMs behave the same way in mainland China. Mainland Chinese mobile networks are subject to internet restrictions that affect access to some overseas services. Certain international roaming and travel-eSIM arrangements route traffic through infrastructure outside mainland China, which may allow access to services that are otherwise blocked on an ordinary mainland connection. Other arrangements may behave differently. This means that two plans with the same data allowance can provide different experiences. A connection that successfully loads websites does not necessarily guarantee access to Google, Gmail, WhatsApp, Instagram or YouTube. If access to specific services matters to you, check the provider's current documentation and terms before purchasing. Don't assume that every travel eSIM bypasses mainland internet restrictions or that a VPN will always work. For more details, read our guide to VPNs and blocked apps in China. ### How to install an eSIM before your trip 1. Purchase a plan that covers mainland China and confirm its activation rules. 2. Connect to reliable Wi-Fi and install the eSIM using the provider's QR code, app or installation link. 3. Label the line clearly, such as “China data”. 4. Keep the eSIM's activation instructions and customer-support details somewhere accessible offline. 5. Check which line is selected for mobile data and whether the provider requires data roaming to be enabled on the travel eSIM. 6. Disable data roaming on your home SIM if you want to avoid unexpected roaming charges. Keep your home line active only if you need it and understand any applicable charges. 7. Follow the provider's instructions for when to turn on the eSIM and when its validity period begins. Do not delete an installed eSIM simply because it is not connecting. Some profiles cannot be reinstalled freely after removal. Contact the provider first. --- ## Option 2: International roaming If your home mobile provider offers a roaming package for mainland China, this can be the simplest option. Your existing phone number remains available, and you may be able to receive calls, texts and banking verification codes as usual, subject to your provider's terms. Before travelling, compare the cost of roaming against a travel eSIM and check: - Whether the package specifically covers mainland China. - Whether the price is charged per day, per data allowance or by usage. - The data limit and any reduced speeds after the limit is reached. - Whether calls and SMS messages are included or charged separately. - Whether hotspot use is permitted. - Whether the package must be activated before departure. - Whether receiving SMS messages or answering calls can incur charges. Roaming can be worthwhile for a short trip if the price is reasonable and keeping your home number accessible is important. For longer trips, compare the total cost rather than looking only at the daily rate. Also check how your provider handles international data routing. Roaming does not guarantee that every overseas app or website will work. --- ## Option 3: A local Chinese SIM card A local SIM can be useful if you're staying in China for several weeks or months, need a mainland Chinese phone number, or want to use services that require local phone-number verification. China's major mobile operators include China Mobile, China Unicom and China Telecom. Foreign visitors can apply for a mobile SIM using their passport at an operator's own service hall. China's telecommunications authorities published updated guidance for foreign applicants in April 2026\. Applicants must attend in person with valid identification, and the operator's published rates and package conditions apply. Before visiting a shop: - Bring your original passport. - Make sure your phone is unlocked. - Check that your handset supports the relevant network technology and is compatible with the operator's SIM. - Confirm the shop accepts applications from foreign passport holders. - Compare available data, call-minute and validity packages. - Ask how to top up your balance and manage the account. Official guidance says the phone should support 5G or VoLTE. Compatibility can depend on your exact handset, so don't assume that a phone working in your home country will support every Chinese network feature. You can check official operator service-hall locations through their customer-service channels: - China Telecom: 10000 - China Mobile: 10086 - China Unicom: 10010 A local SIM often makes more sense for an extended stay, but it is not automatically the cheapest choice for every visitor. Compare the actual package price and the effort involved with a travel eSIM or roaming plan. ### Will a local SIM give you access to every app? No. A local SIM provides a connection to a mainland Chinese mobile network; it does not remove the restrictions that apply to some overseas services. If access to particular international apps is important, check your connectivity options before choosing a local SIM as your only connection. --- ## Which option should you choose? **For a week in Beijing and Shanghai:** A travel eSIM or a suitable roaming package is usually the easiest choice. **For two weeks across several cities:** A travel eSIM with sufficient data is convenient. Roaming can be a useful alternative or backup, depending on your provider and budget. **For a month or longer:** Compare local Chinese SIM packages with longer-duration travel eSIMs. A local SIM is especially useful if you need a mainland Chinese number. **For work or frequent travel:** Consider your data usage, hotspot requirements, access to overseas services and the importance of keeping your home number reachable. You may prefer a combination of services rather than relying on one connection. **For the least setup:** Choose a roaming package from your home provider, confirm the total price and make sure mainland China is covered. If your phone supports two active lines, you may be able to keep your home number available for calls or SMS while using a travel eSIM for data. However, simultaneous operation depends on your exact phone model, regional variant and carrier support. Check the manufacturer's documentation before relying on this arrangement. --- ## Before you land: checklist - Confirm that your phone is unlocked and supports your chosen SIM or eSIM. - Verify that your plan covers mainland China, not just Hong Kong or Macau. - Check activation timing, data allowance, roaming settings and hotspot restrictions. - Install your eSIM in advance if the provider permits it. - Save the provider's support details and activation instructions offline. - Disable data roaming on your home line unless you intend to use a roaming package. - Download offline maps and translation packs. - Save your hotel address in Chinese. - Set up your payment apps and verify that you can sign in. - Keep an alternative way to contact your accommodation if your connection fails. --- ## Troubleshooting ### No signal after landing First, confirm that the relevant SIM or eSIM line is enabled and selected for mobile data. Check whether data roaming needs to be enabled for that line, as required by the provider. Then try toggling airplane mode, restarting the phone and allowing it to select a network automatically. If the connection still fails, check the provider's supported networks and coverage details or contact its support team. ### Data works, but some apps won't load This may be caused by mainland internet restrictions, the provider's routing arrangements, an app-specific issue or a service outage. Test another website, check the provider's guidance and use appropriate alternatives where necessary. Do not assume that a working data connection guarantees access to every overseas service. ### The eSIM won't install Check that you're connected to reliable Wi-Fi and follow the provider's installation instructions. Confirm that the phone is compatible and unlocked. If installation still fails, contact the provider before deleting a partially installed profile or purchasing another plan. ### Speeds are slow Check your signal strength, data allowance and any speed restrictions in the plan's terms. Try moving to an area with better reception and restarting the connection. If the problem continues, check whether the local network is congested or contact the provider. --- ## FAQ ### Do I need a Chinese phone number to travel in China? Not usually. A travel eSIM or international roaming plan can provide mobile data without a Chinese number. Some local services may require a mainland Chinese number for registration or verification. ### Can I use my home SIM in China? Yes, if your provider supports roaming in mainland China and your plan or account permits it. Check the rates and coverage before departure. ### Will an eSIM let me use Google and WhatsApp? It depends on the plan's connectivity arrangements and how it routes traffic. Some travel eSIMs may allow access to these services, while others may not. Check the current terms for the exact plan you intend to buy. ### Is a local SIM cheaper than a travel eSIM? It can be, particularly for longer stays, but not always. Compare the actual package price, data allowance, validity period and any additional costs before deciding. ### Can I buy an eSIM after I land? Often, yes, if your phone is compatible and you can get online to purchase and install a plan. Buying and installing it before departure is usually more convenient, especially if you want a connection as soon as you arrive. ### Can I use two SIMs at once? Many phones support two active lines, but the available combinations vary. Some support one physical SIM and one eSIM, while others support two eSIMs. Device model, region and carrier restrictions can affect availability. ### Does a travel eSIM give me a Chinese phone number? Not necessarily. Many travel eSIMs are data-only. Check whether the specific plan includes a phone number, voice calls or SMS before purchasing. --- ## Final thoughts For most short visits to China, a travel eSIM or international roaming package is the easiest way to get connected. A local Chinese SIM is worth considering for longer stays or when you need a mainland Chinese phone number. The important thing is to choose a plan that suits your phone, itinerary, budget and connectivity needs. Confirm the coverage and activation rules before departure, prepare offline alternatives and keep your provider's support details handy. A few minutes of preparation can save a lot of frustration when you arrive.
