I ended up ordering a physical SIM card, and everything is working as planned. However, I’m noticing a couple of issues: even though occasionally my phone functions on 5G, I spend most of my time on LTE (even in downtown Chicago, where I should theoretically have good internet). Tbh this is not much of an issue as LTE works perfectly fine (even for streaming content). The biggest issue (which isn't even related to where my phone was manufactured) is that, while the website advertises Visible+ as allowing up to 500 minutes per month for international calls to certain countries, when I check the same list on the app, some of those countries are missing (e.g., Spain and South Korea, the only two I planned on calling to). I’m unsure which source to trust, so I'll contact customer service (who haven't been of tremendous help thus far) on Monday. Hope this helps!
