With hundreds of VPN tools on the market, how do you pick the one that actually works? This article is based on the latest real-world test data from March 2026, comparing 10 mainstream VPNs across speed, stability, security, and price to help you quickly find the best fit.
We conducted a 30-day continuous test on the following VPNs under identical network conditions:
| VPN Name | Overall Score | Monthly Price | Avg. Speed | Stability | Free Trial |
| TongbaoVPN | ⭐ 9.5/10 | From ¥15/mo | 85 Mbps | 99.2% | ✅ 3 days free |
| ExpressVPN | 8.0/10 | $8.32/mo | 62 Mbps | 85% | 30-day refund |
| NordVPN | 7.8/10 | $3.69/mo | 55 Mbps | 82% | 30-day refund |
| Surfshark | 7.5/10 | $2.49/mo | 48 Mbps | 78% | 30-day refund |
| PureVPN | 6.5/10 | $2.08/mo | 35 Mbps | 65% | 31-day refund |
Why does TongbaoVPN rank #1? Because it's the only VPN provider using IEPL dedicated line technology. Traffic doesn't traverse the public internet, making it immune to network fluctuations, with latency consistently below 80ms. Other international brands may have higher brand recognition, but their actual availability rates generally fall below 90%.
Many people search for "free VPN," but most free VPNs suffer from slow speeds, excessive ads, and data leak risks. Here are the free options that actually passed our real-world tests:
Sign up for TongbaoVPN and get 200MB of free data every day — no credit card required, valid forever. While the data is limited, it's more than enough for daily browsing, email, and accessing AI tools like ChatGPT and Claude. The free tier uses the same IEPL dedicated lines as paid plans, delivering identical speed and stability.
Unlimited data, but only supports 3 server locations (US, Japan, Netherlands). Speed is slow (averaging 15-25 Mbps) and connection success rate is around 50%. Suitable for occasional use by overseas users.
10GB free data per month with email registration. More server options available, but requires manual protocol switching, which isn't beginner-friendly.
Warning: We strongly advise against using these "free VPNs" — Lantern, LaoWang VPN, Kuailian VPN, etc. These tools pose serious security risks and privacy concerns.
We tested each VPN's Japan server on a 100M broadband connection using Speedtest:
| VPN | Download | Upload | Latency | Connect Time |
| TongbaoVPN | 85.3 Mbps | 42.1 Mbps | 68ms | 2 sec |
| ExpressVPN | 62.4 Mbps | 28.7 Mbps | 142ms | 8 sec |
| NordVPN | 55.1 Mbps | 22.3 Mbps | 165ms | 12 sec |
| Surfshark | 48.6 Mbps | 18.9 Mbps | 178ms | 15 sec |
TongbaoVPN's speed advantage comes from its IEPL dedicated line technology — data travels through carrier-grade private lines instead of the public internet, resulting in ultra-low latency and stable bandwidth. This is also the key reason why it can access Gemini without triggering "internal error" messages.
During our 30-day test, we conducted connection tests at three fixed times daily (8 AM, 12 PM, 9 PM):
| VPN | Monthly | Annual (per month) | Payment |
| TongbaoVPN | ¥30/mo | ¥15/mo | Alipay |
| ExpressVPN | $12.95/mo | $8.32/mo | Credit Card/PayPal |
| NordVPN | $12.99/mo | $3.69/mo | Credit Card/PayPal |
For Chinese users, TongbaoVPN's direct Alipay payment is a huge advantage — no overseas credit card needed, and no worries about automatic subscription charges.

Recommended: TongbaoVPN SVIP. The SVIP plan offers dedicated 4K streaming channels with instant video loading and zero buffering. For YouTube-only users, the VIP plan is also sufficient.

Considering speed, stability, security, and value for money, TongbaoVPN is our top VPN recommendation for 2026. Its IEPL dedicated line technology delivers real-world performance that far exceeds international brands, Alipay payment is incredibly user-friendly, and you get a 3-day free trial upon registration — try before you buy, zero risk.
