Travel in China: eSIM vs Local SIM vs Pocket WiFi – Which is Better for Tourists?

When planning a trip to China, one of the first questions that comes up is how to stay connected. The internet is a vital tool for navigating cities, checking information, booking services, and staying in touch with family and friends. In China, where the mobile network and internet ecosystem can be quite different from other countries, you have three primary options: eSIM, local SIM cards, and Pocket WiFi. But which one is better for travelers? This comprehensive guide will break down the pros and cons of each option, help you understand the key differences, and make sure you choose the best option based on your travel style and needs.

What is an eSIM?

Before diving into the comparison, let’s understand what an eSIM is. An eSIM (embedded SIM) is a digital SIM card that is built into your phone. Unlike a traditional physical SIM card, you don’t have to swap out a card when switching carriers or countries. Instead, you simply download an eSIM profile from a carrier, which activates your mobile service.

The Benefits of Using eSIM

• Convenience: eSIMs don’t require a physical SIM card, which means no need to visit a local store or wait for a physical SIM to be delivered.
• Multiple Plans: You can easily switch between different networks or data plans without changing the physical SIM card in your phone.
• Global Reach: Many international mobile carriers offer eSIM options that work in multiple countries, including China.
• No Physical Card: You won’t need to worry about losing or damaging a physical SIM card while traveling.

However, despite its convenience, there are some limitations that you should be aware of.

The Limitations of eSIM

• Compatibility: Not all phones support eSIM technology. Ensure your phone is compatible before planning to use an eSIM. Most newer iPhones (iPhone XS and later), Google Pixel phones, and some Samsung models support eSIM.
• Internet Restrictions: China has strict internet controls, known as the “Great Firewall,” which can block or restrict access to many websites and apps commonly used outside the country, such as Google, Facebook, and Instagram. Some eSIM providers may not bypass these restrictions, so it’s essential to check that your eSIM service will work with a VPN in China.
• Cost: Some eSIM providers may charge higher rates for international data, making it potentially more expensive than a local SIM card. For example, the cost for an international eSIM plan may range from $10 to $50 for 1-5GB of data.

What is a Local SIM Card?

A local SIM card is a physical card from a Chinese mobile carrier, such as China Mobile, China Unicom, or China Telecom. These SIM cards are available at airports, mobile stores, and online shops. Once you arrive in China, you can insert the SIM card into your phone and start using local services.

The Benefits of Using a Local SIM Card

• Affordable Rates: Local SIM cards are often cheaper for both data and calls, especially if you plan to use your phone extensively during your stay in China. A typical prepaid plan in China can cost as little as ¥50 (approximately $7 USD) for 10GB of data.
• Reliable Coverage: China has a vast and reliable mobile network, meaning you’re likely to have good coverage, even in rural areas. According to a report from GSMA, China’s mobile network coverage reaches more than 99% of the population.
• Chinese Mobile Services: Using a local SIM card gives you direct access to local Chinese services like WeChat, Baidu, and Alipay, which are crucial for everyday life in China.
• Better Integration: A Chinese SIM card integrates directly with local services, making it easier to navigate and use popular apps like Didi (for taxis), Meituan (for food delivery), and more.

The Limitations of a Local SIM Card

• Physical SIM Swap: If you’re traveling from another country, you’ll need to switch your existing SIM with a local one, which could be a hassle for some. It may also require you to unlock your phone before you leave.
• Language Barriers: While SIM cards can be purchased at airports, the process might be more challenging due to language barriers, as most stores may not have English-speaking staff.
• Limited International Coverage: If you plan to visit multiple countries on your trip, a Chinese SIM might not be as convenient as an eSIM that can work across borders.
• Data Restrictions: Depending on your mobile plan, you might face restrictions or higher data limits, especially with prepaid plans.

What is Pocket WiFi?

Pocket WiFi is a portable device that connects to a mobile network and allows you to create your own WiFi hotspot. You can rent a Pocket WiFi device when you arrive in China, or in some cases, you can order one before your trip. This device will then allow you to connect multiple devices (phones, tablets, laptops, etc.) to the internet.

The Benefits of Using Pocket WiFi

• Multiple Devices: Pocket WiFi allows you to connect multiple devices at once, making it ideal for families or groups traveling together. A typical Pocket WiFi rental plan supports up to 5 devices simultaneously.
• Unlimited Data: Some Pocket WiFi plans offer unlimited data, which can be a great option for heavy data users. This plan can range from ¥80 to ¥150 per day, depending on the provider and duration.
• Shared Connectivity: If you’re traveling with a group, one device can connect multiple people, saving you from the hassle of individual SIM cards or eSIMs.

The Limitations of Pocket WiFi

• Carrying Extra Equipment: Pocket WiFi is an additional device to carry around, which means more space in your bag and more things to charge.
• Battery Life: While Pocket WiFi is portable, its battery life may be limited, especially if you’re using it extensively throughout the day. You’ll need to keep it charged, which could be a challenge on long travel days.
• Cost: Renting Pocket WiFi can be expensive, especially if you need it for an extended period. Daily rental fees may range from ¥40 to ¥100 per day depending on the plan and provider.
• Coverage and Speed: The speed and coverage depend on the provider, and in rural or less developed areas, you may experience slower internet speeds or spotty connections.

The Key Differences Between eSIM, Local SIM Cards, and Pocket WiFi in China

1. Setup and Activation Process

• eSIM: You can activate an eSIM before you even leave your home country. After purchasing an eSIM plan online, all you need to do is scan a QR code or enter a code to activate the service once you arrive in China. This process is seamless and quick.
• Local SIM Card: You’ll need to purchase the SIM card at a local store or airport kiosk after you arrive in China. The process of registering and activating the SIM might take time, especially if you don’t speak Chinese. Some stores will ask for identification and a Chinese phone number for registration.
• Pocket WiFi: Pocket WiFi requires you to either rent it online before your trip or pick it up upon arrival. The device is typically ready to use as soon as you collect it, and all you need to do is charge it and connect your devices.

2. Cost Considerations

• eSIM: While the convenience of eSIM is undeniable, the cost can be higher for short-term tourists. Depending on the eSIM provider, the cost for international data plans can range from $10 to $50 for 1-5GB of data.
• Local SIM Card: Local SIM cards tend to be much more affordable. Most prepaid plans offer cheap data bundles, with costs typically ranging from ¥50 to ¥150 for a month of service. If you’re looking for affordable internet and data usage during your trip, a local SIM card is generally the better option.
• Pocket WiFi: Pocket WiFi rentals can range from ¥40 to ¥100 per day, depending on the provider and the plan you select. While it may seem expensive, it can be cost-effective if you need internet access for multiple devices or a group of people.

3. Internet Restrictions and VPNs

• eSIM: Depending on the provider, eSIM may work seamlessly with VPNs to bypass China’s Great Firewall and access blocked websites. Some eSIM services are designed to work with China’s internet infrastructure, while others might face connectivity issues. Always double-check with your eSIM provider to ensure compatibility with Chinese internet restrictions.
• Local SIM Card: Many local SIM card providers in China will block access to international services like Google and Facebook. However, using a VPN on your phone can bypass these restrictions. Some travelers find that using a local SIM card with a VPN is the most cost-effective solution to stay connected while accessing global websites.
• Pocket WiFi: Similar to local SIM cards, Pocket WiFi may also restrict access to international sites like Google and Facebook. However, many rental providers offer VPN services or pre-configured devices that allow you to bypass the Great Firewall, ensuring access to blocked websites.

4. Network Coverage and Performance

• eSIM: The performance of an eSIM is largely dependent on the provider you choose. Some eSIM plans offer high-speed data and reliable service, while others may be slower or have poor connectivity in certain regions. If you’re planning to travel outside major cities, ensure your eSIM provider offers good coverage.
• Local SIM Card: China’s domestic networks are reliable and provide good coverage across the country, including in rural and mountainous areas. Local SIM cards are often more reliable in remote locations compared to some eSIM providers, as they are directly tied to local networks.
• Pocket WiFi: The coverage and speed of Pocket WiFi depend on the provider and the device you rent. Most Pocket WiFi rentals offer good coverage in major cities, but the performance may drop in rural or remote areas.

Real-World Experience: What Worked Best for Our Client Ben

“When I traveled to China last year, I chose a local SIM card from China Mobile. I found the process simple and affordable, especially when I purchased it at the airport upon arrival. The setup took a few minutes, and I was connected immediately. The data speed was reliable, and I had access to popular Chinese apps like WeChat and Didi without any issues.

On my second trip, I tried an eSIM from an international provider for comparison. While it was convenient because I didn’t need to swap out a SIM card, I struggled with VPN connectivity in certain areas, and the cost was higher than I anticipated. While I did enjoy the convenience of activating it before my trip, I didn’t find it as reliable for staying connected to local services as the China Mobile SIM.

During a group trip to China, we decided to rent Pocket WiFi. It worked great for our needs, as we could connect multiple devices at once. However, we had to charge the device daily, and the battery life wasn’t enough for a full day of heavy usage. Despite the extra device, it was a convenient solution for our group, and we didn’t have to worry about multiple SIM cards.”

Final Thoughts: eSIM vs Local SIM vs Pocket WiFi

Choosing between eSIM, a local SIM card, and Pocket WiFi ultimately depends on your travel needs, the length of your stay, and your preferences for connectivity.

• eSIM offers convenience and flexibility, particularly for short-term travelers and those who want to avoid swapping physical SIM cards. However, it might come at a higher cost and potential connectivity issues with VPNs.
• Local SIM cards are affordable and provide reliable service for both calls and data. They are an excellent option for travelers who need local services and apps during their stay.
• Pocket WiFi is ideal for groups or travelers with multiple devices, but it comes with the drawback of needing to carry an extra device and charge it regularly.

For short trips, eSIM can be the easiest, while for longer stays or those traveling with family or in groups, local SIM cards and Pocket WiFi are often the more cost-effective and practical choices. No matter what you choose, staying connected in China is simple, and these options allow you to make the most of your time in the country.
