Staying Connected in China: SIM Cards, Wi-Fi, and VPNs

Remaining connected is essential for any traveler, and China offers several convenient options. This guide explores eSIMs, pocket Wi-Fi devices, local SIM cards, and public Wi-Fi to help you stay online during your trip.

eSIM Options

What is an eSIM?

An eSIM (embedded SIM) is a digital SIM card built directly into your device. This technology allows you to activate a mobile data plan without the need for a physical SIM card. Many contemporary smartphones, tablets, and smartwatches are equipped with eSIM capabilities.

Using eSIM in China

  • Availability: Several international eSIM providers offer data plans specifically tailored for use in China. You can conveniently purchase and activate these plans before you even begin your journey. Popular providers like Airalo and Holafly offer eSIM options for travelers, typically with a pre-allocated amount of data valid for a specific duration, such as 7, 14, or 30 days.
  • Activation: Once you've selected and purchased an eSIM plan, the activation process generally involves scanning a QR code or manually entering an activation code within your device's settings. It's crucial to ensure your device is eSIM-compatible and to meticulously follow the instructions provided by your chosen eSIM provider.

Pocket Wi-Fi (Mobile Wi-Fi Devices)

Renting a Pocket Wi-Fi Device

  • Where to Rent: Pocket Wi-Fi devices can be rented from various sources. Many major airports in China, including Beijing Capital International Airport and Shanghai Pudong International Airport, have dedicated rental counters. You can also conveniently rent them online through services like Klook or Wi-Fi Egg. Additionally, some hotels within China may offer pocket Wi-Fi rental services for their guests.
  • Cost and Data Limits: The cost of renting a pocket Wi-Fi device varies depending on factors such as the daily data allowance and the length of the rental period. Typically, you can expect to pay around $5 to $15 per day. Data plans can range from 1GB per day to unlimited data options.
  • Using the Device: Upon receiving your pocket Wi-Fi device, simply turn it on. It will establish a local Wi-Fi hotspot, allowing you to connect multiple devices such as your phone, tablet, and laptop using the provided Wi-Fi password. Be aware that the device's battery life can be limited, so it's advisable to carry a portable charger.

Local SIM Cards

Buying a Local SIM Card

  • Locations: Local SIM cards are readily available for purchase at airports, official stores of major telecommunication operators (China Mobile, China Unicom, and China Telecom), and some convenience stores, particularly in larger cities. In Beijing, for example, you can find numerous mobile phone stores in popular shopping districts like Wangfujing or Xidan.
  • What You Need: To purchase a local SIM card, you will be required to present your valid passport for identification purposes. This is a standard procedure across China.
  • Plan Selection: Each of the major operators offers a variety of data plans to suit different needs. If your primary requirement is data for navigation and app usage, look for plans with generous data allowances. For instance, China Mobile might offer a plan with 10GB of data valid for a week at a competitive price. Some plans also include call minutes, which can be beneficial if you anticipate making local phone calls.

Public Wi-Fi

Free Public Wi-Fi

  • Availability: Free public Wi-Fi is widely accessible in many public spaces throughout China, including airports, shopping centers, cafes, and some parks. At airports, you can usually connect to the airport's Wi-Fi network after providing basic information, such as your email address. In cafes, both international chains like Starbucks and local Chinese establishments typically provide the Wi-Fi password upon request.
  • Limitations: However, public Wi-Fi in China does come with certain limitations. Some networks may require a local Chinese mobile phone number to receive a verification code for access. Additionally, the speed and reliability of public Wi-Fi can fluctuate. In crowded areas, the connection speed may be noticeably slower.

Using VPN with Public Wi-Fi

  • VPN Requirement: It's important to note that accessing certain international websites and online services that are restricted within China necessitates the use of a Virtual Private Network (VPN). If you intend to use public Wi-Fi to access such content, employing a VPN is essential. Be aware that not all VPN services are legal in China, so it's crucial to choose a reputable and compliant provider. Examples of VPN services that have been reported to work within Chinese regulations include ExpressVPN and NordVPN.
  • Setting up a VPN: To utilize a VPN, you will need to download and install the VPN application on your device before arriving in China, as some app stores within China may not offer VPN apps. Once installed, follow the setup instructions provided by your chosen VPN service. After installation, you can connect to a VPN server and then access blocked content through the public Wi-Fi network.
