What is the domestic communication fee if I use an overseas local USIM?

I came on an overseas trip and bought a local USIM at the airport.

Then what is the domestic communication fee if I use it like this?

I didn't apply for roaming blocking at all

Is there an overseas data fee or a phone fee even if I use a local USIM?

I didn't intend to use the local USIM, but I suddenly used it, so I didn't apply at all, so I didn't know what happened

If you take out the USIM chip in Korea, it will be blocked by Korean telecommunication companies
There's nothing to come out of
