Oh, sorry for the delay in responding. 😅 Well, to get to the point, nothing's happening. If I do everything from settings, tap on the eSIM I want to activate, and try again, a message appears saying 'activating.' Once the message disappears, nothing happens; just mobile data is activated, and that's it.
I've been thinking this might be due to the lack of Google services. I haven't tried a regular SIM card yet because I'm out of the country, but I'll try when I get back because they don't sell SIM cards from my company here.
