IOS Android over the wall software VPN accelerator ladder recommended

Is it important to jump over the wall (scientific Internet access)? I think everyone knows it, otherwise you won’t be able to read this article, you can’t Google the program code if you can’t go over the wall, you can’t reply to Gmail, you can’t watch YouTube videos if you don’t go over the wall, can the courses bought on Udemy be comfortable to watch? ? Can HBO and Netflix follow dramas? Due to the need for work, business trips and life and study, I often access the Internet in different parts of the country. Based on my own experience and understanding of the software industry, I recommend to readers the best, stable and safe scientific Internet access methods and tools in China. , and has long been concerned about VPN, SSR, WireGuard, V2Ray, blue light and other circumvention and information security technologies.

• StrongVPN, the cheapest price, the most comprehensive cost-effective, supports Alipay payment. I have been using it for about 2 years. Generally speaking, in the past 2 years of use, the annual availability rate can basically reach about 95%, and the server IP will also be updated year round. Windows, Mac and Android users in China can use the "Help" online help window in the lower right corner of the official website, or send a ticket to the customer service on the user's background page to ask for a streamlined client V1 app (specially for the client in China), and directly say that it is used in China. The customer service will help you set it up. The simplified version uses the OpenVPN protocol to log in and connect more smoothly in China , while the standard client of the official website may have connection problems when it is blocked during sensitive periods. It needs to wait for the update to return to normal. Domestic users It is best to connect directly using the OpenVPN protocol with a simplified version of the client suitable for use in China, there are tutorials below . It is more convenient to support Alipay payment. Due to the restrictions of the closed iOS system, there is currently no APP specially provided for the Chinese network environment, and the general iOS version of StrongVPN is not stable against wall blockades. iPhone users are advised to choose ExpressVPN. At present, Strong has discount coupons that can be used. Strong’s network speed is slower than that of ExpressVPN when overcoming the wall, but it is enough for users who don’t just need the resolution of YouTube 1080P and above . StrongVPN official website domain name is blocked in China (software APP can be used normally)
• ExpressVPN (promotional link ) , this one has the best experience in China, the speed is the fastest among the VPNs I have used , and it is also my favorite VPN product, but it cannot be purchased from mirror websites accessible in China, only for clients To update and contact customer service, another ladder is required to open the ExpressVPN official website . It has the most comprehensive device support, and is the first choice for iOS (iPhone, iPad) and Android mobile users . It has been in operation for 13 years (until 2021), and has a good reputation at home and abroad. I believe you are not the first to hear it. , in fact, almost all VPN evaluation websites at home and abroad recommend it in the C position. In terms of security, it is also one of the best in the industry. The encryption algorithm officially called "military level" protects the security of users' online information. Its use in China cannot be called perfect, but it can guarantee an annual availability rate of more than 95% (my experience) in China, and the speed is also the fastest among all the scientific Internet VPNs I have used and tested. It is recommended to use OpenVPN or Lightway protocol (Automatic is also available). Lightway protocol is the latest VPN protocol exclusively developed by Express in 2021, and has a high connection success rate in China . If you encounter a wall upgrade during sensitive periods, if you encounter connection problems with the officially recommended server lines optimized for China, you can switch the L2TP protocol to connect to other nodes. There are also some lines in this protocol that are still available in sensitive periods and can be used as backup options. At present, due to policy reasons, ExpressVPN's Alipay payment channel has been suspended, and priority is given to UnionPay cards (domestic bank cards), VISA and MasterCard credit cards and Paypal (see how to purchase ExpressVPN). ExpressVPN has a full refund policy if you are not satisfied during the 30-day trial period, and the refund is returned to the original payment method.
• Lightyear VPN (additional 10% discount link), the mirror official website can be directly accessed most of the time in China, although the name contains "VPN", but the transmission protocol is SSR, which is actually an airport, produced by foreign Chinese, and its security is not as good as a real VPN, But I have been using it for more than half a year, and the cost performance and experience are still good. LightYear VPN can be used as a backup choice for the first two models, and there are mirror websites accessible in China. My general usage scenario is to use it with the above two real VPNs. It can be used to access the official websites of other VPNs and occasionally watch videos. After all, the speed is not bad. If it involves the operation of important account login and sensitive information, I will still use it. Express or Strong, after all, these two are VPNs developed by major foreign companies, and their security is also more guaranteed. Alipay payment is supported, and the refund time limit of Lightyear VPN is 7 days.
