I got a message when inserted a resr sim with plmn 001 01 but see not signal detected1

[Android Central Question]

Iam using samsung s20 ultra 5g and I have inserted a test Sim with plmn 001 01 . But there is a stop sign on top right.
I also received a error with plmn 001 999 not supported when I turned on the phone.

But I have a similar model ue with test Sim where it works and signal is detected.

By testsetup is 5g in sa mode.

Please help
