Just got back for a 16 day European trip (Germany and Czechia) and my Ubigi eSim worked fine.

I was at 2.9 of my 3GB when I checked just before getting on my flight home at AMS.

I did have a bit of an issue that I don't think was Ubigi related -- I have the Boingo WiFi app on my phone. The WiFi symbol showed in the status bar when in my hotel room but I wasn't really connected -- however the phone that I was, so some apps that were set to up/download on WiFi only thought WiFi was connected and did their stuff and I burned up 700MB on Ubigi I didn't really need to. I deleted the Boingo app and things were fine after that. Boingo was somehow interfering with the hotel WiFi login.

I received (and made) calls and texts on my US T-Mobile SIM just fine.
