Because of the nature of VPN software (changing proxy settings), the anti-virus or firewall might consider it as a threat. During the installation, if you encounter any warning prompts, please choose "allow", "agree", "trust" or similar actions. Otherwise, VPN will not work as it couldn't gain access to change the proxy settings.

Please follow these steps:
Menu in the upper left corner of the App - My Account - My Packages - Click the "Upgrade" button behind the current package - Enter the upgrade package interface:
Select the new plan you want to upgrade to or the number of devices you want to increase under "New Plan" below.
If you only want to add more devices to the original package, please select your current package type in the new package and then add the number of devices below.

The VIP package is a direct dedicated line with extremely fast speed. It supports more devices to be online at the same time. There are 30+ countries and regions to choose from. There is no limit or speed limit. High-end dedicated servers are more stable.

In the split tunneling mode, some apps require setting up a proxy in order to function properly. It depends on whether the app being used supports proxy settings.

The proxy settings are as follows:

• SOCK5 Proxy: Address: 127.0.0.1, Port: 1234
• HTTP Proxy: Address: 127.0.0.1, Port: 9876

• While you try to login on a new device, if the device limit has been reached, you will get redirected to the "Unbind Device" page, from there you can unbind the devices
• Or, you can go to "Menu" -> "App Settings" -> "Device List", click on the device to unbind it.

We understand that sometimes we forget our passwords or even usernames. That is why we make it easy for you. Here is what you can do:

• Forgot username: contact us and provide the payment record screenshot to us. 
• Forgot password: You can click on forgot password in the app.

Global Mode: Access everything with VPN. This might slow down some local websites & apps traffic.

Split Mode: Only use VPN when accessing common GEO blocked (China firewall blocked) websites, e.g. Google, Youtube, Netflix etc. When accessing Chinese websites, use local network without VPN.

You can change the routing mode under App Settings.

If you found certain websites or apps can't be accessed, please change your routing mode settings to "Global Mode".

Contact us if you have any other questions.

The web version of the apps, e.g. Telegram, WhatsApp or Gmail, are using HTTPS, which is supported by split mode. The split mode can only change the routing mode for HTTP (port 80) and HTTPS (port 443). That is why you can access the web version.

For the app version, they might have used any ports. Hence you will need to do one of these steps:

• Use "Global Mode" in routing settings
• Change the proxy settings of the app, below is an example of changing proxy settings for LINE:
  
  

We have found that, some users don't know which server to use after deciding which region to use.

To make it easier for you, we decide to show region only. VPN will automatically select the best performance server within your selected region for you. These are the details:

• Location list only shows the regions. Under the hood, there are hundreds of servers within each region. Upon selecting a region, VPN will connect you with the best performance server according to your network condition.
• If you don't like the connected server, you can always disconnect and re-connect to the same region, you will be connected to a different server.
• You can repeat above step until you are satisfied.

There are several common reasons:

• Slow local internet (without VPN on)
• Certain VPN server location has busy traffic

To troubleshoot the network issues, please follow the steps:

• Check your local network speed by disconnect the VPN;
• While keeping VPN disconnected, switch between WIFI, 4G, 5G to find the troubleshoot your network. E.g. if your wifi has poor connectivity, switch to your cellular 4G/5G.
• Disconnect VPN, switch to another region, and connect;
• If you like to stay in the same region, try disconnect and reconnect to the same region. Even you are selecting the same region, there are actually hundreds of servers behind a single region. Every time you connect, we will relocate a different server for you.
• You can repeat above steps until you find the best server for you.

Activation code redemption is a convenient way provided by VPN for users to activate service benefits. By entering an official activation code (also known as “card code”), users can redeem acceleration time, membership privileges, or other exclusive rewards.

Activation codes are typically used in the following scenarios:

How to use:

The term “VPN cracked version” typically refers to unofficial versions of the software that have been modified through illegal means to bypass payment systems or alter its functionality without official authorization. These versions pose significant security risks, such as trojans, malicious ads, and data privacy breaches, which may lead to account theft, device damage, or complete loss of access to the acceleration service.

We strongly advise all users not to download or use so-called cracked versions. These unofficial versions not only fail to guarantee performance but may also result in account bans and pose unpredictable security threats.

To ensure your online safety and optimal user experience, we recommend downloading the official version of VPN only from the official website or reputable app stores.

The official version of VPN is completely free to use. Users can earn free usage time through features such as “Daily Check-In” and “Invite Friends,” making permanent free usage possible. We are committed to providing a secure, stable, and consistently available acceleration service for all users.

VPN is a well-known acceleration service provider that focuses primarily on privacy protection and security. While its main purpose is to protect your privacy and encrypt your internet traffic, VPN's globally distributed server nodes can indeed offer noticeable acceleration benefits for games hosted on overseas servers.

When considering whether VPN can speed up games, here are some important points to keep in mind:

1. Additional overhead from the accelerator: Using an accelerator may introduce some network overhead since your data is rerouted and encrypted through its servers. This can affect latency and connection speed. If your game servers are located domestically, acceleration may not be necessary.

2. Server location and load: VPN provides a wide range of global server locations. However, if you connect to a server that is far from your game server or heavily loaded, it may negatively affect game performance.

3. Speed and stability: While VPN offers high-speed connections, actual performance depends on your location, network bandwidth, and the selected server. Some servers may not be ideal for real-time gaming, which requires low latency and high stability. Whether a specific game benefits from acceleration through VPN largely depends on your own testing.

Before using VPN or any similar service for gaming, it’s advisable to check user reviews, evaluate service performance, understand the privacy policy, and confirm whether it includes features optimized specifically for gaming. If your primary goal is to improve game connectivity, you may also want to explore dedicated game acceleration services that are specially designed to enhance gaming performance.

VPN is widely regarded as one of the leading virtual private network (VPN) service providers. It offers a range of features and benefits that make it popular among users:

1. Security and Privacy: VPN is known for its strong encryption protocols, which help protect your online activities from hackers. It also has a strict no-logs policy, meaning it does not keep records of your browsing history or connection logs.
2. Network Size and Speed: VPN has a large network of servers located in numerous countries, allowing users to access content from around the world. The service claims to provide fast and reliable connections, which is important for streaming, downloading, or general internet usage.
3. User-Friendly Interface: VPN offers user-friendly apps for various platforms, including Windows, macOS, iOS, Android, and more. The applications are typically considered intuitive and easy to navigate.
4. Customer Support: VPN is known for its responsive customer support team. They offer 24/7 live chat support to assist users with any issues or questions they may have.

While VPN has generally received positive reviews, it's essential to note that individual experiences can vary. It's recommended to research and compare multiple VPN providers to find the one that best suits your needs. Additionally, new features or changes to the service may have occurred since my last knowledge update, so I recommend visiting the VPN website or consulting more recent user reviews for the most up-to-date information.

Although there are free VPNs and proxy services, they are not recommended as they do not offer the same privacy and security benefits of a paid VPN. Many do not work as advertised, some may even sell your data, and most will leave your networks vulnerable to attack.

Our VPN security app provides an additional layer of security between your Mac and the internet so you can browse, shop, and stream content privately and securely. In addition to shielding your identity from online snooping or data mining, a VPN also unblocks websites and content that may not be readily available in your region due to censorship or firewalls from your school or office network.

We recommend that you connect to the VPN every time you go online to keep your data and browsing activity private and secure from your internet service provider, Wi-Fi operator, and others. A VPN scrambles your traffic in an encrypted tunnel so not even your ISP can read it, and it also lets you change your IP address, which prevents your real address from being used to identify, track, or locate you.

VPNs are legal in the vast majority of jurisdictions around the world and are widely used by individuals and companies to protect their data, including in countries with highly restrictive governments. Even where VPNs might be seen as discouraged, many governments tacitly endorse their use by officials, academics, or businesses to stay competitive in an interconnected world. It is simply not practical for countries to ban all VPNs.

Of course, illegal online activity is always illegal, whether you are using a VPN or not.

As more and more digital activity—including banking, browsing, and messaging—happens on mobile devices, it becomes increasingly essential to use a VPN to protect your data, especially when using public Wi-Fi. And people who like to stream video and music on their mobile devices will appreciate having all the same entertainment options on the go that they enjoy with a VPN at home.
