Plug In: Plug that same cable into the back of the ONSIM Box.
Power On: Plug the ONSIM Box into a standard electrical wall outlet.
What’s in the Box?
When your package arrives, you will find everything you need to get started:
The ONSIM Landline Replacement Box: Pre-configured and ready to go.
Power Adapter: To connect the box to your wall socket.
Your ONSIM SIM Card: Already installed inside the device.
