I got a call to go to Europe, and I'm flying out in a few days. But I don't know how the connection will be there, and I don't want to pay crazy money for roaming.

I was in a similar situation when I was sent to Italy in Europe . I also panicked about the internet. Then I found out about eSIM: I just bought an international package online, activated it on the plane, and already at the airport I had access to my email, messengers, and maps. It really saves business trips because you stay connected right away. I was even able to send a presentation to my colleagues on the way from the airport. I recommend you try it, you'll be glad you did.
