I came across a message stating that to use the Mobile Hotspot feature on my phone, I need to insert a SIM card. This got me wondering why a SIM card is necessary for creating a Wi-Fi hotspot. I have a Samsung Galaxy S23 Ultra running Android 13, and I'm looking for clarity on this.

The need for a SIM card boils down to the fact that you're sharing data from the cellular network. A hotspot relies on a cellular connection, so you need a SIM card for that.
You might be a bit confused about how Mobile Hotspot works. It takes your mobile data and shares it as a Wi-Fi network for other devices. No SIM card means no mobile data to share, so that's why it's required.
Most Wi-Fi hotspots use cellular data to offer an internet connection. If you wish to share your existing Wi-Fi, some phones allow it via Bluetooth or USB, but that depends on the specific phone capabilities.
A Wi-Fi hotspot essentially lets other devices use your cellular data over Wi-Fi. Without a SIM card (or eSIM), your phone doesn't have a cellular connection to share, so it can't create a hotspot.
