Chromecast is a streaming device created by the technology company giant Google. It can be used to cast various media content from streaming services, like Netflix, YouTube, Disney+, and others.

Once the wired connection is established, you can now set up your Chromecast device and cast movies without WiFi. If this method doesn’t work for you, check out are article which deals with your ethernet not working.

You can use an HDMI cable to connect your phone to your smart TV. However, you’ll need an MHL (Mobile High-Definition Link) adapter to make this work. It’s also important to ensure that your device is MHL and HDMI-supported

To connect your phone to your smart TV using an HDMI-MDL-USB cable connection, follow these steps below:

  1. Plug the USB end of the MDL cord into your phone. Also, plug one end of the HDMI into the MDL cord.
  2. Insert the other end of the HDMI cable to your smart TV and plug in another USB-A cord to power up the MDL cable.
  3. If the connection is successful, the smart TV can mirror your phone’s screen via HDMI input. You can use this to view saved movies and stream movies using a mobile data connection.


3. Screen Mirroring

This option will require you to have a Chromecast device, a smartphone with the Google Home app installed, and a smart TV that supports screen mirroring. You will also need enough mobile data as an alternative for the WiFi connection.

So, if you’re wondering how to mirror your phone to TV without WiFi using Chromecast, follow the steps below:

  1. Enable your phone’s mobile hotspot and connect your Chromecast device.
