Set Up a VPN Connection auf Samsung
Samsung phones do not come with a built-in VPN provider. Every profile - whether for a company network or a commercial VPN service - has to be entered manually with the server address, protocol type, and login data from your provider.
The relevant function sits inside the network connectivity manager, grouped together with mobile data and Wi-Fi settings rather than as a standalone app. Without a saved profile, apps that expect a VPN tunnel simply fail to authenticate, and regular browsing traffic stays unencrypted on open networks.
Open Settings ➔ Connections ➔ More connection settings ➔ VPN. Tap the menu icon in the top corner and select Add VPN profile. Enter the corresponding data - name, server address, VPN type, and credentials supplied by your provider or IT department - then tap Save.
Once saved, the profile appears in the VPN list and can be switched on per connection. If you only need to unblock a single app rather than encrypt all traffic, an app-level proxy is usually lighter on battery than a full VPN tunnel.
