I’ll be honest โ I didn’t figure any of this out as a tourist. I’m Chinese, but I spent several years in the Philippines, so I’ve been bouncing between the two countries long enough to feel the difference firsthand every time I cross back through immigration.
The first thing I do after landing at any Chinese airport is swap my setup. When I was in Manila, I’d been on a Philippine SIM โ Globe or Smart, mostly โ using Instagram, Google Maps, YouTube without a second thought. The moment my phone picks up a mainland China cell tower, that whole world goes quiet. WhatsApp notifications stop coming through. Google doesn’t load. Even some apps I’d downloaded in the Philippines behave oddly until I reconnect to the right network.
That gap between how the internet works inside China versus outside it is exactly what this guide is about. If you’ve never traveled to China before, the firewall can feel disorienting in a way that’s hard to explain until you’ve actually sat there watching a web page time out. This guide exists so you don’t have to figure it out on the ground.
What’s Actually Blocked in China
The short answer: almost everything you rely on daily.
Google is completely blocked in mainland China โ search, Gmail, Google Maps, YouTube, Drive, all of it. WhatsApp has been restricted since 2017, and as of 2026, you can technically send text messages without a VPN but can’t make calls or send photos without one. Instagram, Facebook, Telegram, and most Western news sites are also blocked. The list is long.
What still works without any setup:
- Apple Maps, FaceTime, iMessage
- Outlook, Teams, Bing, and most other Microsoft services
- Zoom (mostly)
- International banking apps (though occasional instability)
The important nuance: what’s blocked depends on your connection type, not just your location. Hotel Wi-Fi running through Chinese infrastructure? Blocked. Travel eSIM routing through overseas servers? Often not. This is why two people sitting in the same hotel room can have completely different experiences โ one on the hotel Wi-Fi struggling to load Gmail, the other on a foreign eSIM sending Instagram stories with no problem.
Option 1: Travel eSIM โ The Easiest Setup for Most Visitors
When I go back to China to visit family, I keep a Philippine eSIM active with roaming enabled. It’s not the cheapest solution for a long stay, but for short trips it’s the most frictionless thing I’ve found. I land, my phone connects to a local tower, and because the data traffic routes back through overseas servers, Google and WhatsApp just work. No VPN toggle, no troubleshooting.
That’s the same principle behind travel eSIMs sold by providers like Airalo or Trip.com. The eSIM connects to Chinese mobile infrastructure locally โ so you get real 4G/5G speeds โ but the data is tunneled through overseas servers. From the Great Firewall’s perspective, you’re an international visitor, not a domestic connection. Blocked apps bypass the filter by default.
This is why a travel eSIM is usually the first recommendation for short trips:
- Install before departure, activates on landing
- No VPN needed for most day-to-day apps
- Works on both iPhone and most modern Android devices
- Leaves your physical SIM slot free (useful if you want to keep a Chinese number for calls)
For a full breakdown of which providers actually work well in China right now โ data caps, network reliability, 5G coverage โ the Best eSIM for China Travel guide goes deep on that. Two options worth starting with: Airalo and Trip.com eSIM.
One thing to keep in mind: if you’re running a VPN on top of a travel eSIM, turn the VPN off. The two systems can conflict โ and that conflict has a very specific consequence: it breaks Alipay payments. More on that below.
Option 2: VPN โ Essential If You’re on Hotel Wi-Fi or a Local SIM
If you’re connecting through hotel Wi-Fi, public hotspots, or a local Chinese SIM card, you’re on domestic infrastructure. That means the firewall applies, and you can’t access Google, WhatsApp, or Instagram without a VPN.
Here’s the part that catches people out: you have to set it up before you arrive.
Once you’re in China, VPN provider websites are blocked. The App Store in China has most VPN apps removed. If you land without a VPN already installed, paid for, and tested, you’re basically stuck. I’ve seen this happen to friends visiting โ they’d Google “best VPN for China” while on the plane and land without anything actually ready, then spend their first evening asking hotel staff for help.
Set it up at home. Download the app, create an account, connect to a test server. That 20-minute task saves a lot of frustration.
Not all VPNs work reliably in China โ the firewall has gotten significantly better at identifying and blocking common VPN protocols. The ones with obfuscation features (which disguise VPN traffic as regular HTTPS traffic) have better odds of staying stable. NordVPN (/go/nordvpn) is the one I’ve seen consistently recommended in recent testing.

Option 3: Local Chinese SIM โ Worth It for Longer Stays
If you’re staying in China for more than two weeks, or you know you’ll need a Chinese phone number, a local SIM makes more sense than a travel eSIM for data. You can pick one up at China Mobile, China Unicom, or China Telecom kiosks in the arrival halls of most major airports โ bring your passport, as registration is required by law.
The trade-off: local SIM data is on the domestic network. That means you’ll need a working VPN for Google, WhatsApp, and most blocked apps.
Some travelers combine both: local SIM for the +86 number and occasional calls, travel eSIM as the primary data connection. More switches to manage, but it solves both problems cleanly.
Why You Might Still Need a Chinese Phone Number
A travel eSIM gives you internet. It doesn’t give you a +86 number. Those are two different things, and some parts of daily life in China still depend on the latter.
The clearest example is food delivery. Meituan โ the main food delivery platform โ requires a local phone number to register and receive delivery notifications. Without a +86 number, you either can’t use it at all or depend on a friend to order for you. Same goes for some public Wi-Fi networks in malls and train stations, which use SMS verification with a Chinese number to let you on.
Didi (the main ride-hailing app) works without a local number in most situations, but drivers will sometimes call the passenger number if they’re having trouble finding you.
For short trips under 10 days or so, most people manage without a local SIM. For longer stays, or if you’re planning to use food delivery regularly, it’s worth picking one up. Full guide: China SIM Card for Foreigners.
Maps: Why Google Maps Feels Broken
Google Maps in mainland China has two problems, and only one of them is about the firewall.
Even if your eSIM or VPN is working, Google Maps is often unreliable for street-level navigation. The underlying issue is a coordinate system called GCJ-02 โ a deliberately shifted coordinate standard used by Chinese maps. Google’s data doesn’t always apply the correction accurately, which means the blue dot showing your location can be off by 50โ100 meters in dense urban areas. In the maze of a place like a Beijing hutong or an older city district, that’s enough to walk you into the wrong street repeatedly.
Apple Maps in China sources its data from AutoNavi (Amap) โ the same database that Chinese people use. It’s accurate, has an English interface, and doesn’t require a VPN. For most navigation in cities, Apple Maps is the better choice.
If you want local transit options or more detailed walk-throughs, the Amap app also has an English version that’s worth downloading before you leave.

The VPN and Payments Problem
This one is easy to miss until it happens to you.
When you scan a QR code to pay with Alipay or WeChat Pay, the app runs a security check that includes looking at your IP address. If your VPN is routing through a server in New York or London, the app sees a foreign IP trying to complete a payment at a vendor in Chengdu โ and flags it as suspicious. The payment fails, often without a clear error message, just a vague “payment unsuccessful” screen.
The fix is simple but easy to forget if your VPN runs automatically in the background: turn off the VPN before opening Alipay or WeChat Pay. Complete the payment, then turn it back on.
It’s one of those things where knowing the reason makes the solution obvious. If you’re in a queue and your payment keeps failing, kill the VPN first before trying anything else.

What to Sort Out Before You Fly
Most connection problems in China happen because people try to fix them after landing. Here’s what takes 30 minutes at home and saves hours on the ground:
- Buy and install a travel eSIM. Airalo or Trip.com eSIM. Install before departure, only activate when you land.
- Download and test a VPN. Even if you’re using an eSIM, it’s good backup for hotel Wi-Fi situations. Install, log in, and test from home. NordVPN is a reliable option.
- Set up Alipay or WeChat Pay. Link your foreign card at home while you have unrestricted internet access. Both apps are harder to configure from behind the firewall.
- Download Apple Maps or Amap. Apple Maps works without a VPN. Amap (the AutoNavi English app) is better for transit routes.
- Grab key apps before departure. Trip.com, Didi, and any other travel apps are easier to download from your home country’s App Store.
Quick Reference: Which Connection for Which Situation
| Situation | Best Option | Notes |
|---|---|---|
| Airport arrival | Travel eSIM | Activate after landing |
| Hotel Wi-Fi | VPN | Must be installed before entry |
| Alipay / WeChat Pay | Turn VPN off first | IP conflict causes payment failure |
| Food delivery (Meituan) | +86 SIM required | eSIM doesn’t provide a local number |
| Navigation | Apple Maps or Amap | Google Maps is unreliable in mainland China |
| Long trip (2+ weeks) | Local SIM + VPN | Better value; VPN still needed for blocked apps |
| Hiking / remote areas | Offline maps + local SIM | eSIM signal varies outside major cities |
