Band locking in Cat18

What is the way to lock or take out Bands in the Control Software tab or location want to play with my Visible Sim on my local tower…just need to know wher to look in the SW. thanks

Are you looking at the band selection option ?

That’s what I need, which menu tab do you find that?? Wonderful;)

It’s under :
Dashboard —> Cellular “Detail” Button —> Cellular Settings → Band Selection —> Choose Custom

Thanks so much…
