How to Access the Open Internet in China in 2026 (The Honest Guide for Australians)
You've booked your flights. Maybe it's a group tour through Beijing and Shanghai, a business trip, or a long-awaited family visit. Then someone mentions the Great Firewall and suddenly you're googling "how to use WhatsApp in China" at midnight before your flight.
Here's the thing: it's simpler than it sounds. This guide explains exactly what's blocked, what still works, and the cleanest solution for Australian travellers in 2026.
What's actually blocked in mainland China
The Great Firewall (officially called the Golden Shield Project) is China's national internet filtering system. It's been running since the early 2000s and gets more comprehensive every year. On any standard Chinese internet connection, including hotel WiFi and local SIM cards, the following are blocked:
Important note for Hong Kong and Macau travellers: the Great Firewall does not apply in Hong Kong or Macau. Under the "one country, two systems" arrangement, both regions maintain unrestricted internet access. WhatsApp, Google and Instagram all work normally there. The firewall only kicks in when you cross into mainland China.
This is the one that catches people out. When you roam on Telstra or Optus in China, your data routes through Chinese carrier infrastructure. That means the same firewall applies. You'll pay $10 a day and still not be able to open Google Maps. It's genuinely one of the worst value propositions in travel.
The cleanest solution: a travel eSIM built for China
A China travel eSIM connects your phone to an international carrier network that sits outside the firewall entirely. Your data never touches Chinese infrastructure, so Google Maps, WhatsApp, Instagram and everything else just works, the same as it does at home.
There's no app to download, no settings to configure when you land, and no technical knowledge needed. You scan a QR code at home before you leave, and the eSIM activates automatically the moment your plane touches down in Shanghai or Beijing.
The eSIM uses an international carrier's network rather than a local Chinese one. Because the traffic never enters the Chinese domestic internet, the Great Firewall never sees it. Think of it as a direct pipe to the open internet, built into your phone.
Setting it up takes about two minutes
- Check your phone is eSIM compatible. Most iPhones from the XS onwards, Samsung Galaxy S20 and above, and Google Pixel 3 and above support eSIM. The quickest check: dial *#06# on your phone. If you see an EID number in the results, you're good to go.
- Buy your eSIM before you board. Once you're in China, you won't be able to access the purchase page without a working connection. Do this at home.
- Install via QR code. On iPhone: Settings, then Mobile Data, then Add eSIM. On Android: Settings, then Connections, then SIM Manager. Scan the QR code from your confirmation email. It takes under a minute.
- Set it as your data SIM. Make sure your phone is using the new eSIM for mobile data, not your Telstra or Optus SIM. Your physical SIM stays in the phone for calls and Australian texts.
- Land and connect. The eSIM activates automatically on arrival. Open WhatsApp or Google Maps straight off the plane.
What about VPN apps?
VPNs are the other option people try, and they work, but they're genuinely more hassle than a travel eSIM. A few things worth knowing:
- You must download and fully configure your VPN before entering China. Once you're inside the firewall, you can't access foreign app stores or VPN websites.
- Many consumer VPNs are actively blocked in China and update their servers regularly to stay ahead of restrictions. Quality and reliability vary a lot.
- Speeds can be slow, especially on congested servers during busy travel seasons.
- The legal status for foreign tourists is technically a grey area, though enforcement against individual visitors is essentially unheard of.
A travel eSIM sidesteps all of this. No app, no configuration after landing, no reliability concerns.
What does it cost compared to carrier roaming?
Travelren's Greater China eSIM plans start from $4.00 AUD for 3GB over 7 days, up to $72.50 AUD for unlimited data over 30 days. That covers mainland China, Hong Kong and Macau on a single plan.
By comparison, Telstra charges $10 per day for 2GB, and Optus charges $5 to $10 per day depending on your plan. Both still give you a firewalled connection. On a 14-day China trip, the difference between Telstra roaming and a Travelren eSIM is over $130 AUD.

Get your China eSIMCommon questions
Does WhatsApp actually work in China with one of these eSIMs?
Yes. Because your data routes through an international carrier network outside the firewall, WhatsApp, iMessage and every other blocked app work exactly as they do at home. No extra steps required.
Will I still get calls and texts on my Australian number?
Yes. The eSIM handles data only. Your physical Telstra or Optus SIM stays in the phone and continues to receive calls and SMS on your Australian number as normal.
Does it work in Hong Kong and Macau too?
Yes. Travelren's Greater China plans cover all three regions on a single eSIM. It switches networks automatically as you move between mainland China, Hong Kong and Macau. No new SIM needed at each border.
Do I need to do anything special when I land?
Just confirm your phone is using the eSIM for mobile data rather than your Australian SIM. The eSIM activates itself when it detects a compatible network. Most people are connected before they reach the baggage carousel.
