Hello,

I am trying to update EF.EHPLMN with around 20 PLMNs.

With edit_binary_decoded, I am able to add them successfully.

But I am trying to update them directly using  update_binary_decoded command from from the pySim-shell prompt. But I am not working.

It would be really helpful if somebody could help me with it.

Below is the full list of commands that I tried.

Welcome to pySim-shell!
