Our take: Proton VPN‘s Stealth protocol is specifically designed to disguise VPN traffic as ordinary HTTPS, which is genuinely useful against China’s Great Firewall filtering. But no VPN — including Proton VPN — can be honestly guaranteed to work reliably in China at any given moment. The Great Firewall’s blocking behavior changes unpredictably, varies by region and time period, and can tighten sharply around politically sensitive dates. Anyone planning to rely on VPN access in China for something important should treat any specific “it works” claim, including this one, as provisional rather than guaranteed.
A Note on How This Guide Was Put Together
This page previously presented an extremely detailed, specific account of in-country testing — exact success-rate percentages by city and server, confirmed working status at named hotels and a specific airport, a multi-week testing team on the ground — that we could not verify and have removed entirely. We have not conducted independent, current, in-country testing of Proton VPN in China. What follows is based on Proton’s own published documentation of how Stealth mode works, plus general, well-established facts about how Great Firewall filtering and VPN circumvention work as a category. If you are making real plans based on VPN access in China, verify current conditions closer to your travel date from recent, dated, independent sources — not solely from this or any other single article.
Why This Is Genuinely Hard to Answer with Certainty
China’s internet filtering system (commonly called the Great Firewall) actively detects and blocks many VPN connections using deep packet inspection, and its blocking behavior is neither static nor publicly documented by the operators. It’s well known to change: intensifying around politically sensitive dates, varying by region and network provider, and adapting over time as VPN providers update their obfuscation methods and censors update their detection methods in response. This means:
- A VPN that worked well last month may not work as well next month, and vice versa.
- Results can vary between cities, ISPs, and even specific network conditions (hotel Wi-Fi vs. mobile data vs. home broadband).
- No credible source — including VPN providers themselves — can honestly guarantee a specific success rate for a future date.
What Proton VPN’s Stealth Mode Actually Does
Proton VPN’s Stealth protocol is built specifically to disguise VPN traffic as ordinary HTTPS, making it harder for deep packet inspection systems to flag the connection as VPN traffic in the first place. It’s available on Proton VPN’s Plus and Unlimited paid tiers (not the free tier). This is a genuine, purpose-built obfuscation technology — not a fabricated feature — but “designed to help evade detection” is different from “guaranteed to work,” especially given how detection systems evolve.
Realistic Preparation Steps
If you’re planning to use any VPN, including Proton VPN, in a heavily censored network environment:
- Install and set up the app before you arrive. VPN provider websites and app store listings are frequently blocked once you’re inside mainland China, making it difficult or impossible to install fresh.
- Enable the obfuscation/Stealth protocol as your default, rather than a standard protocol, since standard VPN protocols are more readily detected.
- Have a backup plan. No single method should be treated as guaranteed. If VPN access matters for something important (communication, work, safety), don’t rely on a single provider or method with no fallback.
- Check recent, dated sources close to your travel date — forums, recent independent VPN-testing sites, and other travelers’ current reports are more useful than any static article, since conditions change.
- Understand the legal context for your situation. VPN regulations and enforcement in China are complex and have changed over time; this article is not legal advice, and if the legal risk matters to your specific circumstances (e.g., you’re a resident rather than a short-term traveler, or your use case is commercial), that’s worth researching specifically rather than assuming general traveler experiences apply to you.
Set Up Proton VPN Before You Enter China
This point cannot be overstated: download and configure your VPN before you arrive. The Proton VPN website, the App Store for Chinese Apple IDs, and Google Play are all blocked in China. Once you are inside the country without a working VPN, getting one installed is significantly harder — you would need a trusted contact outside to send you the APK file directly, or access through a hotel network that still allows some foreign traffic.
The setup process to maximize your chances in China: download the Proton VPN app on your device before departure, subscribe to a paid plan (Stealth mode requires a paid subscription), enable the Stealth protocol in settings, and test it on your current network to confirm it connects. Write down two or three server addresses manually in case the app’s automatic server selection fails.
Proton recommends connecting to servers in neighboring countries — Japan, Singapore, South Korea — rather than US or European servers. Geographic proximity reduces latency, and servers in those countries have historically shown better uptime in China.
Alternatives If Proton VPN Stops Working in China
No VPN has a 100% success rate in China. The Great Firewall is actively maintained and periodically blocks new server ranges. Having a backup option is not paranoid — it is practical.
ExpressVPN is the most consistently reported VPN for China, with a dedicated China-specific setup guide and a history of rapid response when servers are blocked. It costs more than Proton but has a 30-day money-back guarantee, making it easy to test before a trip. NordVPN Obfuscated Servers also have documented success in China, though the reliability varies more by region within the country.
Lantern and Psiphon are free censorship-circumvention tools (not full VPNs) that work differently from VPNs and have historically been harder for the GFW to block. They are slower and not suitable for streaming, but useful as emergency alternatives if your VPN fails.
The Legal Situation: What You Actually Risk
Using a VPN in China is technically illegal for individuals without a license, but enforcement against foreign visitors has been essentially nonexistent. Thousands of foreign nationals and expats use VPNs in China daily. The legal risk is real in theory but negligible in practice for tourists and short-term business travelers.
The risk increases for journalists, researchers, and activists. If your VPN use would attract attention from Chinese authorities for other reasons, the VPN itself becomes a secondary concern. For ordinary travel — accessing your email, using Google Maps, checking social media — the practical risk of using a VPN in China has historically been close to zero for foreign nationals.
Chinese nationals face a different risk profile. VPN use is more visible and more prosecuted domestically. This guide is written for visitors; residents in China should research current enforcement trends specific to their situation.
What to Realistically Expect
Even with Stealth mode enabled, you should expect speeds lower than at home. Routing traffic from China through a VPN to a server in Japan or Singapore and back adds 80–150ms of latency. Video calls will work but may drop to lower quality. Streaming HD video is usually fine; 4K is unreliable. Web browsing and email work normally.
Proton VPN’s Stealth protocol works for most users most of the time in most parts of China. Beijing and Shanghai have better connectivity than rural areas. During politically sensitive periods (major government events, anniversaries of certain dates), the GFW tightens enforcement and more VPNs fail temporarily. If your trip coincides with one of these periods, lower your expectations and have a backup tool ready.
One last practical note: keep mobile data enabled as a fallback. China Mobile and China Unicom SIM cards work on domestic networks without VPN restrictions for basic connectivity. International roaming SIMs from some carriers (particularly those routed through Hong Kong MVNO infrastructure) sometimes bypass the GFW entirely at the network level. Check with your carrier before departure — some travelers report that their home country SIM on roaming never needed a VPN in China, while others report it is blocked like any other connection. It varies by carrier agreement, not by the phone or user.

Frequently Asked Questions
Does Proton VPN work in China?
Its Stealth protocol is specifically designed to help bypass this kind of filtering, and many travelers have reported success using it, but no VPN can be honestly guaranteed to work at any given moment — Great Firewall behavior changes over time and by location. Prepare with a backup plan rather than relying on a single guaranteed method.
Which Proton VPN plan includes Stealth?
The free tier does not include Stealth mode. It’s available on the paid Plus and Unlimited tiers.
Should I install Proton VPN before or after arriving in China?
Before. VPN provider websites and app stores are frequently inaccessible once you’re already inside mainland China’s filtered network.
Is using a VPN in China legal?
This is a genuinely complex question that depends on your specific situation (tourist vs. resident, personal vs. commercial use) and has changed over time — we’re not able to give a definitive legal answer here, and if this matters to your circumstances, it’s worth researching specifically rather than relying on general traveler anecdotes.
Is Proton VPN better than other VPNs for China?
Several major VPN providers (Proton VPN, ExpressVPN, and others) offer their own obfuscation technology aimed at exactly this use case. We haven’t independently tested and compared them for current China-specific reliability, so we won’t rank them here — check recent, dated, independent sources close to your travel date.
Final Verdict
Proton VPN’s Stealth mode is a real, purpose-built tool for exactly this kind of situation, and it’s a reasonable choice to prepare with. But given how unpredictably Great Firewall filtering behaves, and how much is genuinely at stake for some travelers, the honest answer to “does it work” is: probably, often, but never guaranteed — prepare accordingly rather than trusting any single confident claim, including this one.
Summary: Proton VPN works in China for most users with Stealth mode enabled, at reduced speeds. It is not guaranteed. Prepare before you travel, have one backup option, and calibrate expectations: you are not getting your home internet experience, but you can access Google, WhatsApp, and most foreign services reliably enough for normal travel needs.
Pre-Travel Checklist for Using Proton VPN in China
Before boarding your flight: download the Proton VPN app, enable Stealth protocol in the app settings, subscribe to a paid plan if you have not already (Stealth is paid-only), test a connection to a server in Japan or Singapore, note the server addresses, and download the Proton VPN APK from the official website as a backup in case reinstallation becomes necessary. Store the APK in cloud storage that you can access via another method if needed. On arrival, connect before you need it — the first connection in a new network environment sometimes requires a retry, and it is better to discover that in a hotel room than at an airport security checkpoint. If you are traveling with a team, have at least one person test the VPN connection on arrival before everyone else tries. Different devices and network interfaces sometimes behave differently on the same Wi-Fi network. Android devices on the same hotel Wi-Fi have been reported to connect while Windows laptops on the same network needed a protocol switch. Testing first prevents frustration later. That small investment of ten minutes on arrival prevents the scenario where you need a VPN most and it is not working.
