Thunder VPN Review: A Look at Features and Performance
In the vast ocean of VPN services, Thunder VPN has managed to make quite a splash with over 50 million downloads on Google Play. But as we all know, popularity doesn't always equate to quality. In 2025, with cybersecurity threats evolving faster than ever, can this free Android VPN still hold its ground? Or is it just another case of thunder without the lightning? Let's dive deep into this Thunder VPN review and see if it lives up to its stormy name.
After extensive testing and comparing it with premium alternatives like SafeShell VPN, we've uncovered some shocking truths that might make you reconsider your VPN choices.
Thunder VPN: The Quick Breakdown

- Split tunneling feature

- Free version available
- No account required for basic use
What's Definitely Not Great 👎
- Extremely slow speeds that make basic browsing painful
- Vague and concerning logging policy
- No information about encryption protocols
- Missing essential security features like a kill switch
- Limited server network (only 20+ countries)

Speed Performance
If there's one thing that makes or breaks a VPN service, it's speed. And unfortunately, Thunder VPN breaks rather than makes. During our 2025 tests, the performance was abysmal, earning it a mere 5/10 rating.
We tested Thunder VPN from the Netherlands and compared it to our baseline connection. The results were shocking:
| Server Location | Download Speed (Mbps) | Upload Speed (Mbps) | Ping (ms) |
|---|---|---|---|
| No VPN (baseline) | 36.9 | 36.9 | 16 |
| Netherlands | 29.9 | 4.0 | 46 |
| Germany | 3.99 | 0.45 | 64 |
| UK | 4.56 | 0.48 | 42 |
| US (Virginia) | 4.53 | 0.52 | 112 |
| US (Oregon) | 14.9 | 0.54 | 179 |
| Japan | 10.5 | 0.53 | 544 |
| Australia | 3.66 | 0.55 | 647 |
In contrast, when we tested SafeShell VPN on the same connection, we were blown away by speeds consistently above 90 Mbps across most locations, with minimal impact on our baseline connection.
During daily use, Thunder VPN made even simple tasks frustrating:
- YouTube videos constantly buffered even at low quality
- Mobile games like Hearthstone were unplayable
- Basic web browsing felt like we'd traveled back to dial-up days
Security: Missing the Essentials
When it comes to security, Thunder VPN falls dangerously short of modern standards. The company is mysteriously secretive about its protocols and encryption methods, which is never a good sign in the VPN world.
From what we could gather, Thunder VPN appears to use outdated SSL encryption, which hasn't been updated since 1996 and has known vulnerabilities. Most reputable VPNs today use OpenVPN, WireGuard, or proprietary protocols that offer superior protection.
Perhaps most concerning is the lack of a kill switch – an essential feature that prevents data leaks if your VPN connection drops. Without this protection, your real IP address and browsing data could be exposed at any moment.
SafeShell VPN, by comparison, offers their proprietary "ShellGuard" protocol with military-grade encryption and an automatic kill switch feature that ensures your data never leaks, even during connection hiccups.
Privacy Policy: Vague and Worrying
Thunder VPN's privacy policy raises serious red flags. It's vague, short, and includes concerning statements about data collection. The policy mentions that they collect connection timestamps and ends with an ominous "etc." – suggesting they might collect additional data not explicitly mentioned.
The company behind Thunder VPN, "Signal Lab," is equally mysterious. Based in the US (a member of the Five Eyes intelligence alliance), there's minimal information about the company online, with no official website or social media presence.
For users serious about privacy, this lack of transparency should be deeply concerning. A VPN is supposed to enhance your privacy, not compromise it with ambiguous policies and hidden data collection.
User Experience: Simple But Limited
If there's one area where Thunder VPN doesn't completely fail, it's usability. The app is straightforward and easy to navigate – primarily because it lacks advanced features. However, this simplicity comes at the cost of functionality and customization.
The website is disappointingly basic – just a single page with generic information and a download link to Google Play. There's no detailed FAQ, no transparency reports, and no meaningful resources for users.
Installation is quick and painless, but that's about the only positive aspect of the user experience. The premium (VIP) subscription is overpriced considering the subpar service quality, and payment options are limited to Google Pay.
How Thunder VPN Compares to SafeShell VPN in 2025
When comparing Thunder VPN to a premium service like SafeShell VPN, the differences are stark:
| Feature | Thunder VPN | SafeShell VPN |
|---|---|---|
| Speed | Extremely slow (3-15 Mbps) | Ultra-fast (90+ Mbps) |
| Server Network | 20+ countries | 100+ countries |
| Streaming Support | Doesn't work with Netflix | Optimized for Netflix, Disney+, HBO, etc. |
| Security Protocols | Outdated SSL (likely) | Proprietary ShellGuard protocol |
| Kill Switch | None | Yes, automatic protection |
| Logging Policy | Vague, collects timestamps | Strict no-logs policy, audited |
| Device Support | Android only | Windows, macOS, iOS, Android, Apple TV, etc. |
| Simultaneous Connections | 1 (free), varies (premium) | Up to 5 devices simultaneously |
| Customer Support | Almost non-existent | 24/7 live chat and email support |
| Price | Free (limited), Premium overpriced | Competitive pricing with free trial |
I tried using Thunder VPN for streaming my favorite shows while traveling, and it was a complete disaster. Not only could I not access any geo-restricted content, but the connection would drop every few minutes. When I switched to SafeShell VPN, not only could I access Netflix US, UK, and Japanese libraries, but the streaming quality was perfect – no buffering, no interruptions, just smooth HD streaming.
Who Should Use Thunder VPN?
Honestly? Almost no one. Even as a free VPN, there are better options available. The only scenario where Thunder VPN might be acceptable is for very occasional, non-sensitive browsing when absolutely no other option is available.
If you're serious about:
- Streaming content from platforms like Netflix
- Protecting your privacy online
- Enjoying fast, reliable connections
- Securing multiple devices
...then you should look elsewhere. SafeShell VPN offers a much more robust solution with actual security guarantees and performance that won't leave you pulling your hair out.
Frequently Asked Questions About Thunder VPN Reviews
Is Thunder VPN safe to use in 2025?
Based on our testing and the vague privacy policy, we can't recommend Thunder VPN as a safe option. The lack of transparency about protocols, the mysterious company ownership, and the concerning logging practices all suggest that your data might not be as protected as you'd hope.
Can Thunder VPN unblock Netflix and other streaming services?
No. In our tests, Thunder VPN failed to access Netflix, Disney+, Hulu, and other streaming platforms. The slow speeds would make streaming painful even if it did work. For streaming, SafeShell VPN is a much better choice with its optimized streaming servers.
Is Thunder VPN really free?
Thunder VPN offers a free version with limited features and server options. However, the premium version is surprisingly expensive given the poor performance and limited feature set. As the saying goes, if you're not paying for the product, you might be the product – especially concerning given their vague privacy policy.
What's the best alternative to Thunder VPN in 2025?
SafeShell VPN stands out as a superior alternative with lightning-fast speeds, excellent streaming capabilities, and robust security features. Unlike Thunder VPN, SafeShell offers transparent policies, modern encryption, and reliable performance across all major platforms.
Does Thunder VPN work in other restricted countries?
No. Thunder VPN lacks the obfuscation technology needed to bypass sophisticated censorship systems. More advanced VPNs like SafeShell have specialized features designed to work in heavily restricted regions.
In conclusion, while Thunder VPN might have once been an acceptable free option, in 2025's cybersecurity landscape, it falls dangerously short. With superior alternatives like SafeShell VPN offering better performance, security, and value, there's little reason to risk your privacy and sanity with Thunder VPN's subpar service.
