eSIM FAQ FAQ

Why do I need an eSIM if I have international data roaming? What apps can I access?

International data roaming is often very expensive and even then, you may not be able to access many foreign websites and apps in China because of the Great Firewall.
With an eSIM, travelers can stay connected affordably and access most of their everyday apps like Gmail, WhatsApp, and Maps. Some apps such as TikTok and ChatGPT can be tricky to use in China, but we list which eSIM providers support access to them on our comparison page for your convenience.

Is eSIM safe? Is it banned in China?

Yes, it’s completely safe to use an eSIM for travel in China. And it’s not banned in China. Many international travelers use eSIMs every day.

Can I use it on my phone or tablet? Any device restrictions?

Yes. You can use an eSIM on any eSIM-compatible phone or tablet. Most newer devices support eSIMs, and providers clearly list compatible models on their websites (example).

Is eSIM delivered online?

Yes. Your eSIM will be delivered instantly online through a QR code right after purchase. You can also find our free setup guide here (Saily, Airalo, Trip.com)

Can I have a phone number with an eSIM in China? What happens to my current number?

All the eSIMs we list are data-only, meaning:

You won’t get a new Chinese phone number. Because of China’s real-name registration policy, most eSIMs for travelers can only offer data service, not voice or SMS.

And You’ll keep your current phone number active on your main SIM (so no impacts on your current number).

Does the China plan include Hong Kong or Macau?

Usually, China-only eSIMs do not include Hong Kong or Macau. However, many providers offer regional plans that cover China, Hong Kong, and Macau together. Be sure to check the coverage details before purchasing.

How much data do I need?

It depends on your usage:

  • Light users: around 0.2 GB per day (checking email, light browsing)
  • Average users: around 1 GB per day (social media, maps, messaging)
  • Heavy users: 2 GB or more per day (streaming, video calls, etc.)

You can check the provider data usage guide for more details and recommendations.

How do I install it?

Installing an eSIM is very simple. After purchasing, you’ll receive a confirmation email with step by step guidance. You can also find our free setup guide here (Saily, Airalo, Trip.com). Each provider also includes detailed instructions to help you through setup (example).

When should I install it?

It’s best to install and activate your eSIM before arriving in China. You can find our free setup guide here (Saily, Airalo, Trip.com). Most eSIM providers also offer clear, step-by-step instructions to guide you through the process.

What happens if I run out of data?

Most providers will notify you before your data or validity expires. You can usually top up your plan manually, and some providers even offer auto top-up options for convenience.

What if my eSIM isn’t working?

First, If the network doesn’t connect right away after you arrive in China, try toggling Airplane Mode or restarting your phone to refresh the connection, this solves the problem 99% of the time.

If it’s still not working, then double-check that:

  1. Your device supports eSIM.
  2. You’ve followed the installation and activation steps correctly.
  3. You have turned on the China eSIM (turning off all other eSIMs) and disallow the auto data switching

If it still doesn’t work, contact the provider’s 24/7 customer support. All providers we recommend offer quick technical assistance.

Can I request a refund if I don’t like it?

Yes. All the providers we list offer 24/7 customer support and a refund policy if the eSIM doesn’t work properly or doesn’t meet your expectations.

VPN FAQ FAQ

What’s differences between eSIM and VPN? Which one should I choose?

Both eSIMs and VPNs are popular choices for travelers to China, especially if you want access to Western websites. Both allow you to enjoy unrestricted internet access in China, so you can still use your everyday apps and websites like Gmail, YouTube, and WhatsApp.

They also have some differences:

  • Connectivity: An eSIM provides a data plan, so you don’t need Wi-Fi. A VPN, however, requires an existing internet connection (Wi-Fi or hotspot).
  • Speed & Convenience: Depending on your setup, a VPN can sometimes be faster or easier to use, especially on laptops.
  • Cost: VPNs are typically more affordable, particularly if you use large amounts of data.
  • Setup: Both are simple to install, but VPNs are generally easier to set up.

The big question is: which one is right for you? It depends on your travel needs, but here’s what we generally recommend:

  • If you don’t have a China SIM card, an eSIM is the better choice, it gives you mobile internet access and helps you bypass the Great Firewall. You can find the top eSIM provider comparison here.
  • If you already have a China SIM card, a VPN is the better option to access Western websites and apps securely. You can find the top VPN provider comparison here.
  • If you need both data and unrestricted access, consider using both an eSIM and a VPN for the best experience.

Can I get both eSIM and VPN?

Yes, many travelers choose this option, especially if they want both data and unrestricted internet access.

When to install?

Be sure to download your VPN app before traveling to China, as most VPNs are blocked there. Once installed, you can subscribe anytime, most travelers do it before their flight. You can find the step by step free VPN setup guide here ( Surfshark, Nord, LetsVPN)

Is VPN legal and safe in China?

Yes, but with caution. Although China has strict regulations for VPN providers, it’s still legal for travelers to use a VPN as long as the provider complies with Chinese laws. Always choose a trusted provider, as some unsafe VPNs may collect your data. Check out our recommended VPNs here for reliable options.

Can I ask for refund if I don’t like it
