The Smart DNS feature works by changing the DNS servers on your device from your local ones to our DNS servers.
Smart DNS does not change your IP address, only your DNS addresses.
This feature will help you unlock streaming services worldwide because most apps on gaming consoles, Apple TVs etc rely on DNS enquiries.
Smart DNS does not encrypt your data. For this reason, this feature can be used for streaming but not for security reasons.
If the WeVPN app is compatible with your device, you do not need to use the Smart DNS feature.
