The Samsung Freestyle 2nd Generation projector has a micro HDMI port that can be used to connect to external devices such as Blu-ray players or consoles. However, there is no direct HDMI port specifically designed for connecting mobile phones. To connect a mobile to the projector without using Wi-Fi, there is no direct HDMI connection option. Instead, you can use wireless mirroring technologies such as Apple AirPlay 2 or Smart View for Samsung devices to transfer content from the mobile to the projector.

To use the projector without Wi-Fi, you could theoretically connect an external device such as a laptop or console via HDMI, but there is no viable HDMI solution for directly connecting a mobile phone without Wi-Fi.

### Possible connections:
- Micro-HDMI: For connecting to external devices such as consoles or Blu-ray players.
- Wireless mirroring: Via AirPlay 2 or Smart View for transferring content from mobiles to the projector.

### Recommendation:
For a wired connection without Wi-Fi, it would be best to use an external device with an HDMI output.
