How to use your phone in China

I. Understanding about Mobile Network Standards in China

China mainly utilizes 2 major mobile network standards: GSM (global system for mobile communications) and CDMA (Code division multiple access). 

  • GSM: is the most widely used standard all over the world, which allows for both voice and data communication. It runs on different frequency bands, which are 900MHz and 1800MHz, usually known as 2G. In China, GSM offers good coverage of networks in both urban and rural areas.
  • CDMA: is less popular but still utilized by a number of cellular network operators in China. It runs on the frequency bands of 800 MHz and 1900 MHz. This technology is associated with 2G and 3G networks, and less compatible with the global standards.

=> So how do these standards impact phone compatibility? We answer below.

II. Quick Checklist of Using Cell Phone for Travelers to China

When traveling to another country, we rarely need to make analog voice calls on our phones. If you are like most travelers, you may need Internet access for staying connected, getting map directions, booking hotels, buying airfare or using a translator. 

Because WiFi is not always available and secured, getting connected to a Chinese network is important. 

First of all, you need to know a simple traveler’s checklist when it comes to using a phone in China. Read on to see more details!

1. Check Your Cell Phone’s Compatibility

If your cell phone is manufactured after 2015, then it may be compatible with China’s networks. However, if your mobile phone is of older models, it may not work with international bands. 

That is why you should check your phone’s frequencies. Make sure that it covers the international frequencies of 900 Hz and 1800 Hz. 

Below are the network frequencies / mobile bands available for tourists when traveling in China.

Frequencies typeBands
2G bandsGSM 900, GSM 1800
3G bandsUMTS 2100
4G bandsLTE 850 (5), LTE 2100 (1
5G bands5G 3500 (78)

You may want to know:

  • The newer and higher-end your cell phone, the higher chance it will work. If your phone is of GSM tri-band or quad-band, it will work in China. 
  • The North American dual-band will not work in China.
  • All iPhones (quad-band) and the latest models of Samsung Galaxy phones will also work (either tri- or quad-band)

2. Ask Your Home Network Carrier

Make a call or visit to your home network carrier and ask them what type of rates they are offering for international roaming. Make sure that you know the rates of voice calls, SMS texting and data usage, what it costs per Mb/Gb.
You can save money if you only use data. 

3. Check If You Cell Phone is “Carrier-unlocked”

Ask your network carrier if your cell phone is locked or unlocked. If you know a little bit about technology, you can do a self check of your phone’s IMEI number to see whether or not it is unlocked. 

If it is, you can buy Chinese SIM cards for tourists (either before departure or after landing in China).

If your cell phone is locked with the current carrier, you either need to use international roaming or rent a phone.

4. Do You Have a VPN?

It is advised to set up a VPN on your phone before you depart to China. 


The reason is that there are some services blocked in China and using a VPN will help you bypass the block. 

For example, if you cannot use Facebook and other Google services in China, look for a reliable VPN provider, download the app prior to departure. In case it does not help you, you may get your money back (this varies depending on the policy of each VPN provider)

5. Check Your Charger Plug

It is not strange when you get nervous about charging your cell phone when traveling in a new country. Fortunately, most mobile phones, laptops and tablets have a charger which supports the 220V service in China. But, it is necessary to double check to see if your current plug fits the electrical sockets of China. 

You have gone through the quick checklist on using a phone in China. 

Now you may wonder “Will my cell phone work in China?”

Let’s see the answer below!

III. Will My Mobile Phone Work in China?

Will my phone work in China

It depends. There are 02 issues to consider:

  • Can your device communicate with Chinese frequencies?
  • Your home provider’s plan is activated for international service or not. Many service providers, especially in the US, require international service to be activated. If you do not activate it before departure, your cell phone will not work in China or other international destinations.

Most of the time, your phone will work in China and you do not need to do anything. After landing in China, you just need to turn on your phone and it will automatically build up a connection and you will be charged with international roaming by your local mobile network provider. 

In some cases, you may need to modify your phone’s settings and switch on “data roaming”.

However, this is the most expensive option available. 

In fact, there are some other options to consider. The problem now is to choose the best one for you to use. 

There are many options available for you to use your mobile phone in China. We will review one by one in the section below.

2. Buy a Prepaid Chinese SIM Card (work with unlocked phones)

To use this option, you first need to make sure your cell phone is unlocked (as mentioned earlier).

Once you have an unlocked cell phone, you need to buy a Chinese SIM card. 

How to use: Insert a plastic SIM card into an unlocked mobile phone.

Where to buy: Buy it online before departure, at the airports, metro stations, train stations, convenience stores, hotels and cellular phone carriers’ stores. There are many mobile phone providers in the country: China Unicom, China Mobile and China Telecom. China Mobile’s 4G network runs on TDD-LTE – unique to China. China Telecom and Unicom’s 4G networks run on FDD-LTE – used by most countries. 

What to buy: 2 options: data only or data + voice + SMS

Registration process: require personal information like passport/ID card. 

3. Rent or Buy a WiFi Pocket

For those who cannot use the above methods, take this option into consideration. 

That way, you can have your own portable WiFi hotspot. 

WiFi Pocket or Mobile WiFi (MiFi) is a device connecting to the Internet via a wireless local area network (WLAN). It contains a SIM card and allows users to connect to the local 4G network and access the Internet while traveling. This acts as a hotspot which mobile devices can connect to the Internet. 

It works with both phones, tablets and laptops. You can also share with other devices (be it your own or your friends). However, this option does not allow you to make analog calls/SMS, but via apps like Skype, FaceTime,…

How to use: log in with the given account and password, then connect to the Internet.

Where to buy: search and rent them online and you can pick them up at the airport upon arrival or have them delivered to your hotel where you will stay. There are shops offering Mobile WiFi renting service at the airports in Shanghai or Beijing.

Price: pay either by the day or month

Registration process: no need

4. Use eSIM for Tourists

This is a new way to stay connected while traveling. It works similarly to a physical SIM card but does not require you to insert anything into the cell phone. You just need to pay for the plan you choose, receive an email with details of your plan, download the eSIM info by scanning a QR code or import information manually. That way, you can stay connected after landing in China. No SIM card delivery, no SIM registration,…

How to use: require an unlocked, eSIM-compatible mobile phone. Just buy it online, scan QR code to install and activate. No need to remove the main SIM card. Check out our list of eSIM compatible devices HERE.

Where to buy: buy it online in your hometown before departure (most recommended) or after arrival in China, from eSIM providers like Chinaesim.com, Gigago, Airalo, Holafly, Nomad, etc.

What to buy: data-only (no analog calls or SMS), but still make calls or send texts through apps.
Price: vary by provider and plan. Oftentimes, it is more expensive than physical SIM card plans but it is worth every penny. 

Registration process: no need to register your personal info.

Bonus feature: some China eSIM providers (like Chinaesim.com or Gigago.com) offer eSIM without the need of VPN so you can use the Internet in China without restrictions. It is super convenient!

5. Use Free WiFi in China

The most economical way to stay online during your trip, but coming with low security. Some can be connected directly without a password and some need. The speed is often slow for this type of Internet connection. 

Where to get it: from train stations, airports, hotels, restaurants, cafes, famous attractions, parks,…

Price: free (but in fact, sometimes, you need to pay a small fee for buying something (ex. At a coffee shop) in order to have password for free WiFi

Note: Many public WiFi networks in China require text verification. You may be required to submit a Chinese phone number to get a security code via text to use the WiFi.


If you need to use your cell phone on the go for getting directions, booking hotels, translations, or using social media, you should use a Chinese SIM/eSIM.

V. Tips when using your home cell phone in China

  • Check the rates that you will be charged per phone call / text message.
  • Roaming charges may bite your pocket without you even knowing and even when you do not make any calls or send any text messages. For example, if your phone gets a call, even when you do not answer it, you will still be charged.
  • Be careful with data roaming charges when using apps or services such as email through your cell phone. Now and then, data refreshes may happen periodically without your notice. Thus, you should check your phone’s settings to allow for manual refresh or warrant it either on the airplane mode or completely off to avoid any unwanted charges.
  • If you use your cell phone or LTE/3-4G – enabled device, you are advised to get a local China SIM card/eSIM.


Which mobile networks operate in China?

The major networks are China Mobile, China Unicom, and China Telecom. China Mobile is the largest.

What wireless technologies are used?

2G is mostly GSM, 3G is mostly WCDMA/HSPA on China Unicom and TD-SCDMA on China Mobile, 4G/LTE is mostly FDD-LTE on China Unicom/Telecom and TDD-LTE on China Mobile. Check your phone’s network compatibility.

How do I get a local SIM card? 

Go to an official carrier store with your passport. Prices and required registration have increased over time. Consider a Hong Kong or international roaming SIM to bypass registration.

Will my non-Chinese phone work?

Maybe – check network compatibility above. 2G usually works but performance varies, 3G/4G depends on bands supported. Consider renting a local phone if yours is incompatible.

How do I access blocked websites?

Use a reputable VPN app before and during your visit. Basic VPN use is tolerated but recent regulations have increased blocking and surveillance of VPNs.

Can I call international numbers? 

Enable an IDD prefix like 12593 for reasonable rates. Consider VoIP calling over WiFi as moblie rates are high.

Are there any other restrictions? 

Follow regulations around SIM registration and content. Be aware of state surveillance of communications and online activities. Local mobile apps like WeChat are widely used.
