What does “mobile network state disconnected” mean?

[Amiberkemo]

My phone shows “mobile network state disconnected” and I’m not able to use mobile data. I’m not sure what’s causing this issue. Can someone explain what it means and how to fix it?

The phrase “mobile network state disconnected” refers to when the cellular network your phone should be using does not have an active connection with it. This could be due to many factors such as poor network coverage, SIM problems, the airplane mode being turned on, network malfunction, or incorrect settings.
