What is my subnet mask on my phone?

Excuse me, could you please assist me with a technical query regarding networking? Specifically, I'm wondering how I can determine the subnet mask for the network connection on my mobile phone. I'm aware that subnet masks are typically associated with desktop computers and wired networks, but I'm curious if there's a way to view or set this for my mobile device as well. Is it a setting that's accessible through the phone's operating system, or perhaps a tool that I can download to help me determine it? Any guidance you can provide would be greatly appreciated.
