How to Use eSIM China for Seamless Connectivity During Your Trip

Hello everyone, I’m Alex Chen, a passionate independent traveler from China. I enjoy exploring lesser-known destinations, especially within China, in search of unique travel experiences. I’m also a firm believer in traveling on a budget, which is why I’m always on the lookout for cost-effective ways to stay connected while abroad. In this article, I’ll guide you on how to use eSIM technology to solve your connectivity issues during your travels. As eSIM becomes more widespread, travelers no longer need to rely on traditional SIM cards, offering a more flexible and affordable way to stay connected. This article will dive into how eSIM Chinaworks, how to use it in China, and how to choose the best eSIM provider to optimize your travel experience and avoid expensive international roaming fees.

What is eSIM?

eSIM (Embedded SIM) is a virtual SIM card technology that differs from traditional physical SIM cards. eSIM is directly embedded into the device, eliminating the need for inserting or swapping physical cards. This technology allows users to manage multiple network services easily, activating different carrier networks through software configurations. For travelers heading to China, eSIM is an ideal option, as it eliminates the hassle of purchasing a local SIM card upon arrival, while also supporting data roaming and fast network connectivity. With eSIM, network configuration becomes more flexible and convenient.

How Does eSIM Actually Work?

The way eSIM works is quite simple. After purchasing an eSIM plan, users will receive a QR code or an activation code. By scanning the QR code or entering the activation code, users can download and configure their eSIM. Unlike traditional SIM cards, eSIM is digital and doesn’t require a physical card, saving space and making management easier. With a phone or other device that supports eSIM, users can choose to activate a local or international network plan and connect to the carrier’s network. eSIM technology supports multiple network options, allowing users to switch between networks freely, which is perfect for travelers who need short-term stays abroad or those who need multi-country roaming.

Difference Between eSIM and SIM Card

Can You Use eSIM in China?

Absolutely! Since you’ll need a VPN to access services like Google in China, there are typically four network options for travelers to China: using eSIM, enabling international roaming, buying a local SIM card, or using a Wi-Fi Router. Below is a summary of these four options, including their advantages, disadvantages, and the most cost-effective solutions.

1. Using eSIM: No need to change your SIM card. You can activate the eSIM online directly and connect through both global and local Chinese carrier networks.
2. Enabling International Roaming: Use your home country’s SIM card with international roaming, but be aware that it can be quite expensive, and some apps may not work properly.
3. Buying a Local SIM Card: Purchase a local SIM card after arriving in China, which works well for most domestic communication and payment needs, but you may need to provide identification.
4. Using a Wi-Fi Router: Rent or buy a Wi-Fi router, which is suitable for multiple people to use. However, you’ll need to carry extra equipment, and some local Chinese apps might not be accessible.

Benefits of Using eSIM in China

• Easy Activation, No Need to Swap Cards: With eSIM, you can activate it directly through your phone or other device online, eliminating the need to purchase or swap SIM cards after arriving in China. This saves you from long lines, registration, and card insertion, making it a great option for short-term travelers.
• Cost-Effective: Compared to activating international roaming, eSIM is usually much more affordable, especially for visitors who need short-term data. eSIM plans are very reasonable, helping you save on high roaming fees. You can choose the best data plan according to your individual needs.
• No Need for Identification: When purchasing and activating an eSIM, you don’t need to provide identification documents like a passport or ID card, unlike with traditional SIM cards. Most eSIM providers allow for online purchase and activation, making it quick and easy. This is especially convenient for travelers who prefer not to share personal details during the activation process.
• Supports Multiple Networks and Plans: eSIM allows users to choose from multiple carriers and plans on the same device, providing travelers with more options. This is especially useful for those who need to roam across multiple countries.

Drawbacks of Using eSIM in China

• Device Compatibility and Activation Requirements: Not all devices support eSIM, especially older phone models or devices from less mainstream brands. Before opting for eSIM, you should confirm that your device supports this technology. Some devices may require specific settings or actions to activate eSIM.
• No Local Phone Number, Many Apps Won’t Work: Since eSIM usually doesn’t provide a Chinese local phone number, many local Chinese apps (e.g., Alipay, WeChat, Didi) require users to bind their phone number. As a result, travelers using eSIM may not be able to use these apps, affecting daily activities like payments and transportation. Solo travelers may still need to purchase a local SIM card once in China to access these services.
• Signal Issues in Remote Areas: While eSIM generally works well in most cities, there may be signal and stability issues in remote areas. For example, regions like Tibet may experience poorer signal strength and reliability compared to traditional SIM cards.

Top eSIM Providers in China

In China, all network and call services are provided by the three major Chinese carriers (China Mobile, China Unicom, and China Telecom). However, these three carriers do not offer eSIM services, so you’ll need to purchase eSIM services through third-party providers. It’s important to note that because eSIM services are based on local carriers, the three major carriers cover all of China. Except for a few remote areas, the network signal, plans, and pricing are quite similar across the country. Additionally, eSIM devices and activation requirements are generally the same. Therefore, when choosing an eSIM in China, the main differences come down to the price and plan options offered by various providers. Since hotels in China typically offer Wi-Fi, 1-2GB of data per day is usually enough for tourists.

Here’s a comparison of common eSIM providers in China, with pricing and plan details:

How to Activate and Use eSIM

1. Purchase eSIM: After selecting and purchasing the eSIM plan that suits your travel needs, you will receive a QR code or activation code, usually provided through email, an app, or the provider’s website.

On this page, you will see an option such as “Add Cellular Plan” or similar. Scan the QR code of the eSIM card, or manually enter the activation code to download and activate the eSIM.
3. Select Carrier: After activation, you will need to choose the network carrier you wish to use. If your eSIM supports multiple carriers, you can select the appropriate service provider based on your needs.
4. Configure Data Plan: After selecting the network, you can choose the appropriate data plan. Most eSIM providers will prompt you to select the size of your data package or roaming options during the setup process.
5. Enable eSIM Data Network: Once you have completed the setup, ensure that your device has enabled the eSIM network. Check in the settings to see if the eSIM has been successfully activated and set it as your primary data connection.
