It seems like you might be referring to a "VPN" service that offers an "annual free plan." A VPN, or Virtual Private Network, is a tool that allows you to connect a computer to a faster, more secure network while hiding your identity from your browser. Some VPNs provide a free annual plan, which could be a good option if you want to use it without paying for it. However, please note that the best VPN services are usually based on a monthly or one-time payment model, especially if you're planning to use it for a long time. Additionally, some VPNs might offer free trials or special offers for new users, but the pricing structure can vary. If you're looking for a "永久免费" VPN service, it's important to ensure that the plan you choose is indeed free and reliable for your needs.
