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:
  
  

• 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

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. ChamVPN 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, ChamVPN 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.

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".

During the installation, if you encounter any warning prompts, please choose "allow", "agree", "trust" or similar actions. Otherwise, ChamVPN will not work as it couldn't gain access to change the proxy settings.
