I used Ubigi in the before times and it worked fine. I signed up for an annual plan, 2gb a month in EU in Dec 2019. It didn't roll over month-to-month but I had a enough trips planned in 2020 it was worth paying for the months I'd miss. Ooops.

I emailed them asking for consideration and was basically told nope (there were also language issues), So I switched my T-Mobile to ESIM and use a physical SIM while in Europe. Of course the iPhone 14 messes that up (as no physical SIM slot). Progress
