Download Configuration File (.ovpn)
The required configuration file (.ovpn) to set up the OpenVPN client as DevicePro SIM-Tunnel can be downloaded directly from the portal 'SIMPro -> DevicePro'. The OpenVPN device login credtials (Username and Password) are included in the configuration file (.ovpn), see here.
- Log in to 'DevicePro'.
- Open the desired OpenVPN-device 'SIM-Tunnel'.
If many SIM cards are already present and the device 'SIM-Tunnel' is not immediately visible, you can quickly find the 'SIM-Tunnel' under Devices -> Search devices by entering, for example, 'openvpn' in the top right filter (or enter the device directly here, e.g. 'v0123456').
- Click on the desired device 'SIM-Tunnel'. At the top left of the tile under Access data, the configuration file (.ovpn) is available for download:
Description of Configuration Files (.ovpn)
The access data (username and password) of the 'DevicePro SIM-Tunnel' are already stored in the corresponding configuration file (.ovpn). Therefore, it is not necessary to enter the username and password when establishing the OpenVPN connection.

DevicePro SIM-Tunnel (recommended)
This configuration file should preferably be used!
The OpenVPN connection is primarily established via UDP port 1194. However, if the connection is not successful within 30 seconds, a TCP connection over port 443 and then over TCP port 1194 is attempted instead.
-
DevicePro SIM-Tunnel (TCP-443)
Only for special cases when a firewall blocks the connection!
The OpenVPN connection is established via TCP port 443.
This configuration file should only be used if UDP port 1194 is blocked by a firewall in the network. TCP port 443 is often not blocked in networks, so this can bypass firewall restrictions and establish an OpenVPN connection. A TCP connection is also not subject to UDP session monitoring by the firewall, in case the UDP 1194 OpenVPN connection is irregularly interrupted by the firewall (due to inactivity).

DevicePro SIM-Tunnel (TCP-1194)
Only for special cases when a firewall blocks the connection!
The OpenVPN connection is established via TCP port 1194.
This configuration file should only be used if UDP port 1194 is blocked by a firewall in the network. Possibly, TCP connections are not blocked in the network, so this can bypass firewall restrictions and establish an OpenVPN connection. A TCP connection is also not subject to UDP session monitoring by the firewall, in case the UDP 1194 OpenVPN connection is irregularly interrupted by the firewall (due to inactivity).
Setting up the OpenVPN Client
Please note that the connection using the configuration file (.ovpn), in which the access data (username & password) are already preset, may only be established by one client at a time. If multiple clients establish a connection simultaneously with the same access data, the connection will be regularly interrupted on all clients!
The downloaded configuration file (.ovpn) must be imported into the respective OpenVPN client. Below you will find detailed instructions for setting up and using the listed OpenVPN clients:
