How to change the "Carrier name" of the Android virtual device (emulator)

Question

I want to change the Carrier name, I have used the following command for this:

adb shell setprop gsm.operator.alpha BNetzA
adb shell setprop gsm.sim.operator.alpha BNetzA

But when I check the "NETWORK" tab of the "SIM 1" section in the DevInfo app, the Carrier name is still on Android
