Does the Ubigi E-sim not let you link to your profile while you’re not in the destination country?

A little worried about my Ubigi e-sim not working. I'm still in the U.S and have it added onto my phone (I can see the option to toggle it and everything, such as data roaming on and whatnot). I'm trying to link it to the Ubigi app on iphone but the app says that it does not detect my E-sim, and customer support said they're seeing it as "unactivated" still. When I turn it on as my main carrier to link it to the app, it has zero bars still and no connection. Just want to make sure this is because I'm not in Japan yet, does anyone have any guidance or common experience on this issue? Thanks.
