Vietnam maintains one of the most active internet censorship systems in Southeast Asia. The government blocks or throttles a rotating list of websites, social media platforms, and news outlets. For most travelers, this means your daily digital routine gets interrupted the moment you step off the plane.
The good news: a VPN solves almost all of these problems. The slightly complicated news: not every VPN works, and there are legal nuances worth understanding before you connect.
This guide covers what gets blocked, which VPNs actually function in Vietnam, the legal situation for tourists, and how to set everything up before you leave home.
What is actually blocked in Vietnam?
Vietnam's internet filtering operates through the country's cybersecurity law, which took effect in 2019. The law requires internet companies to remove content the government deems offensive, and it gives authorities power to block entire platforms when they refuse.
The blocklist changes regularly, but these categories remain consistently affected:
Social media platforms
Facebook has been intermittently blocked or throttled since 2015. In practice, Facebook often works but loads slowly, especially during peak evening hours. Instagram faces similar treatment. The government has pressured both platforms to remove content critical of state policies, and when compliance lags, access degrades.
News and political sites
Several international news outlets, including BBC Vietnamese, Voice of America, and Radio Free Asia, are blocked. The New York Times and CNN sometimes load, sometimes don't, depending on current tensions. Vietnamese-language versions of these sites face stricter filtering than their English counterparts.
Adult content
Pornography sites are universally blocked. This catches many travelers off guard, especially those using hotel Wi-Fi where filters are often stricter than public networks.
Gambling and betting sites
Online casinos and sports betting platforms are illegal in Vietnam, and access is blocked at the ISP level. This includes international platforms like Bet365 and PokerStars.
Streaming services
Netflix, YouTube, and Spotify generally work in Vietnam, but the catalog differs. Some content is region-locked. Vietnamese authorities have pressured Netflix to remove specific films, and YouTube occasionally gets throttled when the government objects to certain videos.
Voice over IP services
WhatsApp calls, Skype, and Zoom generally work, but quality can degrade. Some international calling apps face periodic throttling, especially during politically sensitive periods.
How Vietnam's internet filtering actually works
Vietnam uses a combination of technical and administrative controls. The government operates a centralized firewall system that filters traffic at the international gateway level. ISPs receive directives about which domains to block, and they implement those blocks through DNS filtering and IP blocking.
The system is not as sophisticated as China's Great Firewall. It relies heavily on DNS poisoning, which means the block can often be bypassed by simply switching your DNS server to a service like Google DNS or Cloudflare. However, the government has been improving its techniques, and some ISPs now use deep packet inspection to identify and throttle VPN traffic.
Throttling is more common than outright blocking. Many platforms technically work but run at reduced speeds. This creates a frustrating experience where a website takes 30 seconds to load instead of three, and video calls drop constantly. The throttling often intensifies during evenings and weekends when internet usage peaks.
Which VPNs work in Vietnam in 2026?
The VPN landscape in Vietnam changes frequently. Providers that work perfectly one month may find their servers blocked the next. Based on current testing and traveler reports, these are the most reliable options:
| VPN | Works in Vietnam | Average speed | Price per month | Best for |
|---|---|---|---|---|
| ExpressVPN | Yes | 60-80 Mbps | $6.67 (annual) | Streaming, overall reliability |
| NordVPN | Yes | 50-70 Mbps | $3.99 (2-year) | Budget, large server network |
| Surfshark | Yes | 40-60 Mbps | $2.49 (2-year) | Unlimited devices, affordability |
| ProtonVPN | Yes (paid) | 30-50 Mbps | $4.99 (annual) | Privacy, security focus |
| Mullvad | Yes | 40-55 Mbps | $5.00 (monthly) | Anonymity, no email required |
| Free VPNs (Hola, Opera) | No | Unstable | Free | Nothing reliable |
ExpressVPN remains the most consistent performer in Vietnam. Its obfuscated servers, which disguise VPN traffic as regular HTTPS traffic, work well against deep packet inspection. The service maintains servers in Singapore, Hong Kong, and Japan, all of which deliver acceptable speeds to Vietnam.
NordVPN's obfuscated servers also function reliably. The service offers a larger server network than ExpressVPN, which helps when specific IP addresses get flagged. NordVPN's NordLynx protocol performs particularly well on Vietnamese fiber connections.
Surfshark offers the best value for travelers. The unlimited device allowance means one subscription covers your phone, laptop, and tablet. Speeds are slightly lower than ExpressVPN but perfectly adequate for streaming and video calls.
Free VPNs are not worth the trouble. Most free services either get blocked quickly, throttle speeds to unusable levels, or sell your browsing data. Some free VPNs have been caught injecting ads or malware. Pay for a reputable service.
Setting up before you arrive
The most important step: install and test your VPN before landing in Vietnam. App stores in Vietnam sometimes restrict VPN apps, and downloading over Vietnamese internet can be slow or impossible.
Download the VPN app on all your devices while still at home. Create your account, log in, and connect to a server in a nearby country like Singapore or Japan. Test that your connection works and that you can access the sites you need.
Consider downloading offline maps, translation apps, and any other essential tools before departure. VPNs protect your connection, but they do not guarantee access to every service. Having backup options ensures you stay functional even if your VPN fails.
How to use a VPN in Vietnam: practical setup
Once you arrive, follow these steps:
- Connect to your VPN before opening any apps that might trigger filtering. This prevents your device from establishing a baseline connection that the firewall recognizes.
- Choose a server in Singapore or Hong Kong. These locations offer the best balance of speed and accessibility. US or European servers work but add latency.
- Enable the obfuscation feature if your VPN offers it. This masks VPN traffic as regular HTTPS traffic, making it harder for ISPs to detect and throttle.
- If your VPN stops working, switch servers. Sometimes specific IP addresses get flagged. Changing to a different server in the same country often restores service.
- Restart your device after switching servers. This clears DNS caches that might retain blocked addresses.
Hotel Wi-Fi networks in Vietnam often have additional filters on top of national restrictions. If your VPN works on mobile data but not on hotel Wi-Fi, the hotel may be blocking VPN traffic specifically. In that case, use mobile data or ask the hotel to whitelist your connection.
Is using a VPN legal in Vietnam?
Yes, using a VPN is legal for tourists in Vietnam. The government does not prohibit individuals from using VPN services for privacy or security purposes.
However, the legal situation carries nuance. Vietnam's cybersecurity law prohibits using VPNs to access content that the government has deemed illegal. This includes anti-state propaganda, content that disturbs national security, or material that distorts historical events. In practice, enforcement against individual tourists is extremely rare. The government targets service providers and content creators, not casual users.
The practical risk for most travelers is minimal. Connecting to a VPN to check Instagram or read international news carries virtually no legal consequence. The theoretical risk exists, but no tourist has faced prosecution for routine VPN use in recent years.
One caution: using a VPN to access gambling sites is technically illegal, even though enforcement is lax. If you plan to bet online while in Vietnam, be aware that it violates local law.
What about mobile data and SIM cards?
Mobile data in Vietnam offers better speeds than most hotel Wi-Fi. Local SIM cards with 30 GB of data cost around 120,000 VND ($5) from providers like Vinaphone or Viettel. These SIMs work well with VPNs and often bypass some of the throttling that affects hotel connections.
When choosing a SIM, consider the Vinaphone tourist SIM price guide for current options. Mobile data connections in Vietnam run on 4G and 5G networks, with coverage in all major cities and most rural areas.
Using a VPN over mobile data works the same as over Wi-Fi. The VPN encrypts your traffic before it leaves your device, so the mobile network only sees encrypted data. This often results in faster, more stable connections than hotel Wi-Fi, which may have additional filters.
Common problems and fixes
VPN connects but no sites load
This usually indicates DNS issues. Switch your DNS settings to Google DNS (8.8.8.8) or Cloudflare (1.1.1.1). Most VPN apps have a DNS leak protection feature that handles this automatically.
VPN works for 10 minutes then stops
Your ISP may be throttling VPN traffic after detecting it. Enable obfuscation or switch to a different protocol. OpenVPN over TCP tends to be more stable than UDP in Vietnam.
Specific site still blocked even with VPN
Some services block VPN IP addresses. Netflix, for example, detects and blocks many VPN servers. Try a different server location or use the VPN's dedicated streaming servers if available.
VPN slows down significantly during peak hours
Vietnamese internet speeds drop during evenings, typically 7 PM to 11 PM. This affects everyone, not just VPN users. Switch to a Singapore server, which usually maintains better throughput.
VPN works on phone but not laptop
This usually indicates a configuration issue on the laptop. Check that the VPN app is up to date and that no other security software is interfering. Some antivirus programs block VPN connections.
VPNs and Vietnamese internet speed
Vietnam's internet infrastructure has improved dramatically in recent years. Major cities like Hanoi and Ho Chi Minh City offer fiber connections with download speeds of 100-300 Mbps. VPNs add overhead but generally maintain usable speeds.
On a premium VPN, expect 40-80 Mbps download speeds, which handles 4K streaming, video calls, and large file transfers without issue. Free VPNs often drop below 10 Mbps, which makes even standard web browsing frustrating.
Server location matters. Singapore servers offer the lowest latency, typically 30-50 ms. Hong Kong servers add slightly more latency but sometimes deliver better throughput. US and European servers work but add 150-200 ms of latency, which affects real-time applications like video calls and online gaming.
When you might not need a VPN
Not everything is blocked in Vietnam. Google services work normally. Gmail, Google Maps, and Google Drive function without restrictions. YouTube works, though some videos get geo-blocked. Netflix offers a Vietnamese catalog with local and international content.
WhatsApp and Telegram messaging work reliably. Zoom functions for video calls, though quality can vary. Airbnb, Booking.com, and other travel platforms operate normally.
If your digital life centers on Google products, messaging apps, and streaming services, you might get by without a VPN. The moment you need Facebook, Instagram, or international news, you will want one.
The bottom line
A VPN is essential for most travelers to Vietnam. The country's internet restrictions affect popular platforms, and the throttling can make even basic browsing frustrating. Premium VPNs like ExpressVPN, NordVPN, and Surfshark work reliably, cost between $2.50 and $7 per month, and protect your privacy while traveling.
Install your VPN before arrival, choose a Singapore or Hong Kong server, and enable obfuscation for the most stable connection. The legal risk for tourists is minimal, and the practical benefits are substantial.
Vietnam's internet will continue to evolve, and the blocklist will keep changing. But for now, a good VPN ensures you stay connected to everything you need while exploring one of Southeast Asia's most dynamic countries.
