Ask HN: Best plan for some mobile data for a week?

So we got hit by Hurricane Helene. Not as badly as western North Carolina, but enough to knock out power and internet. And there’s every chance the power comes back before internet does. So:

Does anyone have a go-to place to get some mobile data that doesn’t involve a monthly plan? (If not, anyone know the easiest plan to cancel after the first month?) I’m hoping to use the second eSIM slot on my phone to keep from using up the data on my existing plan _again_.
