许多VPN服务提供免费试用。但是ExpressVPN的30天退款保证比免费的VPN试用更好，它使用户可以使用其全面的高质量VPN功能，而不是简化版本。访问https://www.expressvpn.com/order对其进行测试。
您将完全按预期使用ExpressVPN，可以在94个国家/地区中选择160个服务器位置，适用于任何设备的应用程序，超快速连接以及通过实时聊天提供24/7支持。
ExpressVPN是一项虚拟专用网络服务，可让您绕过检查，保护Internet连接和匿名浏览。如果您不满意，只需在30天内随时取消即可获得全额退款。

Good. Yes
So does this mean your 7 days trial is useless… It would have helped to find out if this app works before I use my money…. I installed the app and changed to a country that was not on your recommended list, still it should work but it doesn't, I still get a msg…. This item is not available in your country
Just put more efforts on mainland China, it doesn't work at times which leads to lame performance.
