Which Network Should You Choose for Your China Travel SIM?
If you’re preparing for a trip to China, choosing the right SIM card will ensure you stay connected to the Internet and can easily share your experiences. China has three major network providers offering SIM cards: China Mobile, China Unicom, and China Telecom. Each of these providers offers different features, coverage, and pricing, catering to various user needs.
1. China Mobile - Extensive Coverage, Even in Rural Areas

China Mobile is the largest network provider in China, offering expansive coverage from urban areas to remote rural regions. With the ability to seamlessly transition between 2G, 3G, and 4G-LTE, China Mobile ensures reliable Internet connectivity across various regions, including those with challenging terrains.
However, one limitation of this network is that its 4G service is not compatible with all phone models. China Mobile offers a range of plans suitable for both locals and international travelers, such as a popular package with 10GB of data and 50 minutes of national calls, priced around 12.78 USD.
2. China Unicom - The Ideal Choice for Travelers

With over 90 million users worldwide, China Unicom is the second largest network in China. Its SIM cards are highly compatible with most international phone models, making it an excellent option for foreign travelers.
China Unicom’s 4G network offers nationwide coverage with stable speeds, making it a great choice for travelers who need fast connectivity without worrying about device compatibility. The most popular plan is a 4GB package priced at about 22.90 USD, perfect for travelers needing moderate data with a focus on stability.
3. China Telecom - Designed for Chinese Phones

China Telecom is the third largest network provider, offering various promotions for new subscribers. However, its SIM cards only support 4G for domestic Chinese devices, making it unsuitable for international travelers. This network primarily caters to local users and those with phones manufactured in China. Although the pricing is flexible, ranging from 7.25 USD for 1GB to 26.11 USD for 6GB, the device limitations make it less ideal for foreigners.
In general, China Unicom is the best choice for foreign travelers due to its compatibility with most international phone models and its extensive nationwide coverage. China Mobile is a second option, offering reasonable pricing and widespread coverage across China.
What Types of China SIM Cards Are Available?

Currently, there are four types of China SIM cards available, each catering to different needs and lengths of stay:
1. 5-Day China SIM
The 5-day SIM is perfect for short-term travelers with high data needs. Once activated, it provides up to 200GB of 4G LTE data, ensuring seamless internet access throughout your stay. After 5 days, the connection automatically ends without any additional steps required.
2. 7-Day China SIM
Designed for travelers spending a week in China, this SIM card offers 7GB of high-speed data. Once the data is used up, the speed will be reduced but the connection will remain active. This SIM card is easy to set up and typically offered by trusted network providers.
3. 10-Day China SIM
Perfect for long-term travelers, the 10-day SIM offers 10GB of high-speed data, distributed at a rate of 1GB per day. This plan is ideal for continuous usage throughout your journey.
4. Permanent China SIM
The permanent SIM is ideal for those needing a long-term connection for work, study, or using apps like Douyin and WeChat. Travelers can contact the network provider or agents in Vietnam to register with a simple process requiring only a passport and personal documents.
Where to Buy a China Travel SIM?
To purchase a China travel SIM, you can choose to buy it in Vietnam or upon arrival in China.
1. Purchase a Travel SIM in China

You can buy a China SIM in Vietnam either directly or online. For in-person purchases, visit stores or agents selling China SIM cards in Vietnam. Staff will assist you with choosing the plan and activating the SIM. Make sure to bring your personal documents for registration.
Alternatively, if you don’t have time to visit a store, you can order the SIM online through e-commerce platforms like Shopee, Lazada, or Tiki. After placing your order and providing your personal details, the SIM will be delivered to your home.
2. Buying a China Travel SIM in Vietnam

If you prefer to purchase the SIM as soon as you arrive in China, head to the SIM kiosks at the airport or visit official network stores like China Mobile, China Unicom, or China Telecom. The process at the airport is straightforward, requiring only your passport for registration, and payment is made in cash.
At the network stores such as China Mobile, you will need to present your passport for SIM registration. However, many stores in China now only accept online payments, so you’ll need an Alipay account to complete the transaction.

1. Activate the China Travel SIM
Android Operating System:
- Turn off the phone and insert the SIM card into the SIM slot (preferably slot 1 if the phone has two slots).
- Power on the phone, turn off “Wi-Fi” and “Airplane Mode”.
- Go to the “Mobile Data” section and enable “Data Roaming”.
- Wait a few minutes for the SIM to detect the signal and activate. If you don’t receive the activation notification within 5-10 minutes, power off the phone and restart it.
iOS Operating System:
- Turn off “Wi-Fi” and “Airplane Mode”, enable 3G network, and activate data roaming.
- Power off the phone and insert the SIM card.
- Restart the phone and check the signal connection.
- Once the SIM is activated, turn on “Mobile Data” to start using it.
Note: Only activate the SIM when you start using it to avoid the SIM expiring before the intended time. The SIM’s validity period is usually 8, 15, or 30 days from activation.

You have two options to top up your SIM:
- At a convenience store or official SIM retailer: Provide your phone number and the amount you wish to top up. However, this method may take some time.
- Using Alipay or WeChat Pay: If you have a Chinese bank account or an Alipay/WeChat Pay e-wallet, you can top up online. Otherwise, you may need to ask someone in China for assistance.
Topping up your China SIM may be challenging and time-consuming. It's recommended to plan ahead based on your travel schedule and usage needs, so you can purchase a SIM with sufficient credit from the start.
Tips for Selecting a China SIM for Independent Travelers

Before deciding to purchase a China travel SIM, consider the following tips to help you choose the right product and make your trip more convenient and cost-effective.
- Choose a travel SIM instead of a local SIM: Travel SIM cards are easier to purchase, with simpler procedures and no restrictions on social media apps. In contrast, local Chinese SIM cards are more complicated, requiring paperwork and are hard to obtain without an Alipay account for payment.
- Choose a 4G data SIM over a voice SIM: If you only need internet access for browsing, sharing experiences, and staying connected on social media, a 4G data SIM is the ideal choice. A voice SIM is only necessary if you need to make calls to Chinese phone numbers.
- Opt for a prepaid SIM: Prepaid SIM cards are ideal for travelers as they are convenient, ready to use immediately without any hidden fees. This type of SIM is widely available and easy to use, eliminating any payment hassles.
- Choose China Mobile or China Unicom: China Mobile offers nationwide coverage, making it perfect for travelers exploring various regions, while China Unicom provides stable 4G speeds in urban areas, ideal for those staying mainly in large cities.
- Consider the price and validity period: China travel SIM cards range in price from 150,000 to 1,500,000 VND, depending on the plan and duration. Choose a plan that fits your data needs and length of stay to save costs.
China is not only famous for its stunning natural landscapes and rich cultural heritage but also serves as an exciting destination for Vietnamese tourists eager to discover new experiences. To make your trip more complete, a China SIM card is an essential tool to have.
