Our Picks in Detail
Using a VPN in China: Legal Considerations and Practical Reality
China's Great Firewall blocks most foreign websites and services — Google, YouTube, Facebook, WhatsApp, most news sites, and Netflix are all inaccessible without a VPN. Technically, only government-authorized VPNs are legal in China; unauthorized VPNs operate in a legal gray zone for foreign visitors. Enforcement against individual tourists using VPNs is extremely rare — the law is primarily applied against businesses operating unauthorized VPN infrastructure and against Chinese citizens distributing VPN software.
The practical concern for travelers is not legal but technical: China's Great Firewall is sophisticated, and standard VPN protocols (OpenVPN, WireGuard) are detected and blocked. VPNs that work in China use obfuscation technology that disguises VPN traffic as ordinary HTTPS web browsing, making it undetectable to the firewall. ExpressVPN's Lightway protocol with automatic obfuscation and Astrill's StealthVPN protocol are the two most consistently reliable options for China travel. NordVPN's obfuscated servers work sporadically. The critical rule: download and install your VPN app before you arrive in China. VPN websites and app store downloads are blocked from within China.
Hotel and Airport WiFi Security Risks
Public Wi-Fi networks — hotel lobbies, airport lounges, coffee shops, conference centers — are high-risk environments for unencrypted traffic. The risks are concrete and well-documented:
- Man-in-the-middle attacks: An attacker on the same network can intercept unencrypted HTTP traffic and, in some cases, downgrade HTTPS connections.
- Evil twin networks: A rogue access point with the same SSID as the hotel Wi-Fi (e.g., "Hotel_Guest_WiFi") tricks your device into connecting to an attacker-controlled network.
- ARP spoofing: On shared networks, attackers can redirect local traffic through their device.
- Data harvesting by the network operator: In some countries, hotel networks are required to log user activity.
A VPN encrypts all traffic from your device before it leaves — the hotel network only sees encrypted traffic going to one VPN server IP, regardless of what you are actually doing online.
Accessing Home Streaming Libraries While Abroad
Streaming services detect your location and show you that country's library. Away from home, your Netflix, Hulu, or BBC iPlayer subscription may show a completely different — and often smaller — content library, or be inaccessible entirely (Hulu and Peacock are US-only; BBC iPlayer is UK-only). A VPN with a server in your home country resolves this: connect to a US server to get US Netflix, connect to a UK server for BBC iPlayer.
In restrictive countries, this requires a two-step approach: first, your VPN must use obfuscation to bypass the local censorship firewall and establish a connection at all. Second, once connected, you route through a server in your streaming service's target country. ExpressVPN handles this seamlessly — the automatic obfuscation negotiates the connection in restrictive countries, and you can then select a server in your home country for streaming.
Battery and Data Usage on Mobile
VPN protocols vary significantly in battery and data efficiency on mobile devices. WireGuard and Lightway-based protocols are significantly more battery-efficient than older OpenVPN connections — an important consideration when you are traveling and cannot always charge your phone. On a full day of mobile use with a WireGuard-based VPN, expect 5–15% additional battery drain compared to unprotected browsing. OpenVPN can add 20–30% drain.
Data overhead is typically 5–15% depending on protocol — a 100 MB file download over a VPN might consume 105–115 MB of mobile data. On an international SIM or roaming plan where data is expensive, this overhead is real but modest. Enable split tunneling if your VPN app supports it — this lets you route only sensitive traffic (banking apps, email) through the VPN while streaming video without overhead.
VPN Protocols That Bypass Firewalls
Standard VPN protocols are easily blocked by sophisticated firewalls because they use identifiable port numbers and handshake signatures. Obfuscated protocols disguise VPN traffic as regular HTTPS (port 443) or use traffic obfuscation techniques to appear as normal web browsing. The main obfuscation approaches used by top travel VPNs are: ExpressVPN's Lightway obfuscation (automatic, no user configuration needed), NordVPN's obfuscated servers (select manually in the app), Surfshark's Camouflage Mode (enabled with OpenVPN), ProtonVPN's Stealth protocol (available on all paid plans), and Astrill's StealthVPN (the most reliable for China, though at a higher price). For most travel destinations, any of the top-five picks work fine. For China, only ExpressVPN and Astrill are consistently reliable.
Frequently Asked Questions
Is it legal to use a VPN while traveling internationally?
In most countries, yes — VPN use is legal for individuals. However, a small number of countries restrict or ban VPN use, including China (unauthorized VPNs are technically illegal for individuals, though enforcement primarily targets businesses), Russia (regulated VPNs must comply with censorship requirements), UAE (illegal use of VPN is prohibited though definitions are narrow), Belarus, and North Korea. Research the specific laws for your destination. In China specifically, many travelers use VPNs without incident, but the legal risk is real.
Which VPN works best in China?
ExpressVPN and Astrill VPN have the strongest track records for working in China as of 2026. Both use obfuscation technology that disguises VPN traffic as regular HTTPS — critical for bypassing China's Great Firewall. ExpressVPN's Lightway protocol with obfuscation and Astrill's StealthVPN protocol are the most reliable options. Install and test your VPN before arriving in China — downloading VPN apps from within China is impossible as most VPN websites are blocked.
Can I watch my home Netflix library while abroad?
Yes — connect to a VPN server in your home country and Netflix will show you your home library as if you were still there. ExpressVPN, NordVPN, and Surfshark all reliably unblock Netflix US, UK, and other major libraries. For travel in restrictive countries like China, use a VPN that also includes obfuscation so the connection can establish reliably before accessing Netflix.
