Question 1

What is eSim? How does it work in China.

Accepted Answer

Using an eSIM has become one of the most convenient ways for international travelers to stay connected while visiting China. Unlike traditional physical SIM cards, an eSIM allows travelers to activate mobile data service digitally without changing their existing SIM card. Many tourists now purchase China travel eSIMs before departure and activate them immediately upon arrival, avoiding the inconvenience of searching for local mobile stores at the airport. eSIM services are especially popular because many international providers route internet traffic through overseas networks, allowing users to access websites and apps such as Google, Gmail, WhatsApp, Instagram, YouTube, and Facebook without requiring a separate VPN. This feature is particularly valuable for business travelers, students, and tourists who rely on Western communication and navigation apps. In major Chinese cities such as Beijing, Shanghai, and Chengdu, eSIM users can typically enjoy fast 4G or 5G network coverage for activities including online payments, ride-hailing, translation apps, maps, and video streaming. Popular eSIM providers for China include Holafly, Airalo, Nomad, and ByteSIM, each offering different pricing plans and data packages. Before purchasing an eSIM, travelers should verify that their smartphones support eSIM functionality and ensure the phone is carrier unlocked. Installing and testing the eSIM before departure is also highly recommended. Overall, eSIM technology has greatly simplified internet access for foreign visitors in China and has become an essential travel tool for modern international travel.

If you are visiting China for:
1 week vacation → Holafly or Klook are easiest.
2–3 week trip → Airalo/Nomad-style large data plans are usually better value.
Business travel → ByteSIM or Nomad-style HK-routed eSIMs are usually more reliable.
Families sharing hotspot → avoid “unlimited” plans with aggressive throttling.
Important tips:
Install the eSIM before boarding your flight.
Save QR codes offline.
Download Alipay and WeChat before arrival.
Some “China eSIMs” still require a VPN, so HK-routing matters more than price.

Question 2

What is VPN and why you need it

Accepted Answer

People in China use VPNs (Virtual Private Networks) mainly to access internet services that are restricted or unstable inside China.
Common reasons include:
Access Blocked Websites & Apps
Many international websites and apps are limited or blocked in China, including:
Google
YouTube
Instagram
Facebook
X (Twitter)
WhatsApp
A VPN routes internet traffic through another country so users can access these services.
Work & Business
International companies, researchers, and students often need:
Gmail,
Google Docs,
cloud services,
international news,
or overseas databases.
VPNs help maintain access to global business tools.
Communication With Friends & Family
Travelers and expats use VPNs to:
contact family abroad,
use familiar apps,
watch streaming services,
or access foreign social media.
Privacy & Security
Some people use VPNs for:
encrypted internet traffic,
safer public Wi-Fi use,
or general online privacy.
Streaming & Entertainment
VPNs are also used worldwide — not only in China — to access:
region-locked content,
overseas streaming libraries,
sports broadcasts,
or gaming services.
Important note:

China regulates VPN usage. Officially approved VPN services for businesses exist, while unauthorized VPN services can face restrictions or disruptions. Enforcement varies depending on circumstances and location.

People traveling to China commonly report better success with these VPN services, although reliability can change frequently because access conditions in China are constantly updated:
ExpressVPN
Astrill VPN
NordVPN
Surfshark
Mullvad VPN

An eSIM and a VPN are completely different technologies, although travelers to China sometimes use them together.

cellular data,
phone service,
and internet access.
Instead of inserting a physical SIM card, you download a mobile plan digitally onto your phone.

Often cheaper than international roaming
What an eSIM does NOT automatically do
It does not necessarily bypass internet restrictions
It does not automatically encrypt all traffic like a VPN

VPN

A VPN mainly answers:

“How is my internet traffic routed and protected?”
Examples:

Question 5

How to make a payment in China?

Accepted Answer

While the cost of the trip has been paid before the thrip, there are some occasions that you may need make payments, such as buying souvenirs or getting extra bottle of water. Let's take a look at how to make a payment in China.
In recent years, payment methods for tourists traveling to China have changed dramatically. China has become one of the world’s most cashless societies, with mobile payment platforms such as Alipay and WeChat Pay widely used for everyday transactions. Tourists can now link international credit cards, including Visa and Mastercard, to these apps, making it much easier to pay for restaurants, hotels, taxis, subway rides, shopping, and tourist attractions. In major cities like Beijing, Shanghai, and Chengdu, many stores and street vendors prefer QR-code payments over cash. Although cash is still legally accepted, some small businesses may not have enough change or may be unfamiliar with handling foreign currency. International credit cards are accepted at larger hotels, airports, luxury malls, and international chain stores, but they are not always reliable in smaller local shops or rural areas. Therefore, travelers are encouraged to set up mobile payment apps before arriving in China. ATMs are widely available in cities and usually support foreign bank cards, allowing tourists to withdraw Chinese yuan if necessary. Digital payment systems have made traveling in China more convenient and efficient, but visitors should prepare in advance by ensuring their bank cards work internationally and by downloading essential payment applications. Understanding China’s modern payment environment can greatly improve the overall travel experience and reduce inconvenience during the trip.

Question 6

What are differences between Alipay and WeChat?

Accepted Answer

Alipay and WeChat Pay are the two dominant mobile payment systems in China, but they differ in their origins, functions, and user experience. Alipay was created by Alibaba Group and originally focused on online shopping and financial services connected to e-commerce platforms such as Taobao and Tmall. Over time, it expanded into a comprehensive financial application offering services such as bill payment, investments, insurance, credit scoring, and international payment support. Many travelers find Alipay convenient because it often provides stronger support for linking foreign credit cards and accessing tourist-friendly services.

WeChat Pay, on the other hand, is integrated into WeChat, China’s most popular social media and messaging application developed by Tencent. Instead of beginning as a financial platform, WeChat Pay grew from social communication features such as sending digital “red envelopes” to friends and family. Today, users can make purchases, transfer money, book services, and pay bills directly within the WeChat ecosystem. Because WeChat is already used daily for messaging, social networking, and business communication, many Chinese consumers prefer the convenience of having payment functions integrated into one app.

In practice, both systems are widely accepted across China for restaurants, transportation, hotels, shopping, and entertainment. Many stores accept both platforms, and most Chinese consumers use them interchangeably depending on personal preference and convenience.

Question 7

About translation app

Accepted Answer

Several excellent translation apps can help users communicate effectively between English and Chinese. One of the most popular options is Google Translate, which offers text, voice, camera, and conversation translation. It supports offline language packs and is ideal for travelers and everyday communication.

Microsoft Translator is another powerful tool that provides accurate translations, real-time conversations, and integration with Microsoft Office products. Its user-friendly interface makes it suitable for both personal and professional use.

For users traveling in China, Baidu Translate is a strong choice. It offers high-quality Chinese language translation, voice recognition, and image translation features specifically optimized for Chinese users and content.
