Arriving at the airport before you start looking for a VPN app is often when everything becomes harder than necessary. Some international services and download pages may not be normally accessible, while the verification code is sitting in an email you cannot open. A more proactive approach is to install the app, sign in, and test the connection beforehand.
Quick summary: finish the installation before your trip, test it on the exact device you will bring, and save support instructions so you can read them even when the connection is unstable.
Why prepare before departure?
The Chinese authorities control Internet access, and some popular services such as Google, Facebook, YouTube, and X are blocked. Access can also change over time. That is why preparing in advance is more valuable than a promise that a service will always work everywhere.
The UK Government travel guidance recommends that travelers monitor current regulations and comply with local law. Proton VPN also recommends downloading, signing in, and testing the connection before arriving in China.
Checklist for the 24–48 hours before your trip
1. Choose a plan that fits your trip
Consider three things: the number of days you will use it, the number of devices, and your expected data usage. If you only need maps, email, and messaging, your needs will differ from someone who must join video meetings or download work files every day.
You can view ZaoGuang pricing to compare plans beforehand. Do not choose solely because a plan has the lowest price; the right plan lasts long enough, covers enough devices, and does not force you to buy again halfway through the trip.
2. Download the app for each device
Phones and computers may need different apps. Open the compatible apps directory, choose the correct operating system, and check the source on the publisher’s public page. Avoid files with similar names that come from unfamiliar links.
After installing, open the app at least once and grant VPN permission when the operating system asks. If you are bringing both a phone and a laptop, complete these steps on both devices.
3. Sign in and test the connection
Do not stop at “installed”. Retrieve the subscription link from your account, enter it in the app, and test the connection over Wi‑Fi. Then also try 4G or 5G if possible. This helps uncover password errors, expired links, the wrong app, or missing system permissions early.
4. Save important information for offline access
Take screenshots or save these items in your notes:
- The customer centre address.
- Instructions for retrieving the subscription link.
- The official support channel.
- The plan’s expiry date and device limit.
- Basic steps for changing nodes.
Do not send the subscription link to anyone else. It may contain information that can be used to access your account’s service.
5. Update your device and prepare a backup option
Update the operating system, browser, and apps before you leave, while you still have a familiar connection. Bring a charger, a power bank, and roaming information if your work depends on the Internet. A backup connection does not have to be another VPN; it could be a roaming SIM/eSIM or the Wi‑Fi at your accommodation.
When you first arrive in China
Connect to the network first, then open the VPN app and try the recommended node. If the first node does not work, change nodes instead of repeatedly pressing connect on one configuration. Quality can differ between airport Wi‑Fi, hotel Wi‑Fi, and mobile data.
If you need to use a banking app or a domestic service, it may react to a foreign IP address. When you do not need the VPN, you can temporarily disconnect and try again, but only if you understand that traffic during that time will not pass through the VPN tunnel.
If the VPN will not connect
Try the following in order:
- Change to another node.
- Switch between Wi‑Fi and mobile data.
- Fully close and reopen the app.
- Check that the device date and time are accurate.
- Check whether the plan is still valid and the subscription link has not expired.
- Contact support and include the device, carrier, time, and nodes you tried.
Do not delete the entire configuration as your first step. Specific information helps the support team identify the problem faster than a screenshot that only says “it will not connect”. See also how to choose a route and troubleshoot a slow VPN.
Remember this
No VPN service can guarantee 100% performance on every carrier and at every moment. The Great Firewall changes how it filters traffic, while quality also depends on the region, device, and underlying network. Prepare carefully, keep your expectations realistic, and always follow the law where you use the service.
If you do not have an account yet, you can view VPN plans for China and try installing one before departure.
