I want to route the data we use during our 1-2 day trip through Google servers, yes. It'll be on a fresh number, and then cancelled promptly after our trip, and it'll be a hotspot just for the trip so my wife can communicate w/ her friends. It'll also be used for any incidental calls we may need while there. I usually don't bother and just use wifi calling as needed, but I saw the free 7-day trial and was interested.
That said, someone else mentioned some inexpensive alternatives ranging from $3-6 (airelo, I also found these), so I'll probably just go that route instead. Most no-contract services I've found require buying international credit, so that would be $20+ just for the trip, and that seems a bit ridiculous. I'm willing to pay about $5 for data for the trip, I'm not willing to pay $20+.
