Find the answer “Will my phone work in China?” then learn 04 methods on how to use your phone while traveling China.
Understanding how to use your phone in China is important for travelers because the rules of telecommunication services in China are strict. The Chinese government applies rigorous control over internet access and communication services, which can significantly impact how your phone functions during your visit.

In this article
I. What you need to know about mobile network standards in China
It is common to know that GSM and CDMA are mobile network standards in many countries, including China.
- GSM (global system for mobile communications): This is the most widely used standard worldwide that allows for both voice and data communication.
- CDMA (code division multiple access): is less popular but still utilized by a number of cellular network operators in China.
However, it is noted that these standards are outdated technology and they are primarily associated with 2G and 3G networks. While these still exist in China, they are being phased out in favor of 4G LTE and 5G networks.
Most modern smartphones are designed to work with multiple network standards, including both GSM and CDMA descendants.
For travelers these days, the more important factors are:
- 4G LTE and 5G compatibility
- Frequency band support for these newer networks
- Unlocked status of the phone
- International roaming activation
II. Quick checklist of using cell phone in China for travelers
To ensure a smooth experience with your mobile phone in China, follow this checklist:
1. Check 4G LTE and 5G compatibility
China has extensive 4G LTE coverage in urban and suburban areas. As of 2023, 5G is available in all prefecture-level cities and is continually expanding to smaller cities and towns. Major urban centers such as Beijing, Guangzhou, Shanghai, and Shenzhen have comprehensive 5G coverage.
To ensure optimal connectivity in China, you should:
- Verify that your phone supports 4G LTE at minimum
- For the best experience, especially in major cities, a 5G-capable device is recommended
- Check if your phone supports the specific 4G and 5G bands used in China (e.g., Band 3, 8, 41 for 4G; Band n41, n78, n79 for 5G)
2. Check frequency band compatibility
Your device must support and communicate with the frequency bands used by Chinese network carriers.
- For 4G: Look for support of bands 1, 3, 8, 38, 39, 40, and 41
- For 5G: Ensure compatibility with bands n41, n78, and n79
You should check your phone’s specifications or consult the manufacturer’s website for this information
3. Check unlocked status of your phone
An unlocked phone is essential for using local SIM cards or certain international roaming services:
- Verify that your phone is not locked to a specific carrier. If it is unlocked, you can buy Chinese SIM cards for tourists (either before your trip or after arrival in China).
- If your phone is locked, contact your home network provider to request unlocking. If not contacted, you either need to use international roaming or rent a phone for China.
- Some carriers may have specific requirements (e.g., the phone being fully paid off) before they will unlock it.
4. Check international service activation
Find out whether or not your home provider’s mobile plan is activated for international service use.
You should contact your service provider before your trip and request activation of international roaming.
Be aware that many service providers, particularly in the US, require users to activate international service before traveling. Without this activation, your phone will not function in China or other foreign countries.
Note: the costs associated with international roaming because calls, texts and cellular data can be expensive. Therefore, you should consider alternatives like a local SIM card, an eSIM for affordable data and call rates during your trip in China (we will discuss further below).
5. Check whether or not you need a VPN
If it is advisable to install a reliable VPN to bypass the Chinese Great Firewall before arriving in China.
The reason is because there are some services, websites, and apps blocked by the Chinese government and using a VPN will help you bypass this restriction.
For example, Facebook and Google are two services blocked in China. If you want to use them, you need to find a reliable VPN provider, download the app before departure. If the VPN does not work, you will be refunded (research the policy of the VPN provider you choose).
Tip: Now you have another alternative to access blocked services in China without using a VPN, which is covered by a China tourist eSIM. This is also one of the ways to use your phone in China, which will be mentioned below.
6. Check if your charger and plug work in China
Most mobile phones, laptops, and tablets have a suitable charger which is compatible with the 220V service in China. However, it is important to check if your charger’s plug is compatible with Chinese electrical sockets. China primarily uses Type A and Type I outlets. If your plug does not fit it, you will need to bring an appropriate adapter.
Always double check your charger’s voltage range and plug type before your trip to ensure you can keep your devices powered throughout your stay in China.
III. Will my mobile phone work in China?
The answer to whether or not your phone can work in China will depend on 06 crucial factors, mentioned earlier. However, in most cases, the answer is YES. Your phone WILL WORK in China with minimal effort on your part.
After landing in China, your phone should automatically connect to a local network. In some cases, you may need to switch on “data roaming” manually in your phone’s settings to ensure connectivity.
While international roaming is convenient, it is typically the most expensive option for using your phone abroad.
