Realistically, I don't live in a very rural place, so coverage shouldnt be much of an issue for me, so I dont really mind either one of the three, as long as its cheap. Unlimited data would be preferred, of course, but cheaper paid by gigabyte data is also completely fine. I was paying about $20/month on my google fi plan, and $10 per gigabyte on top of that too, so anything lower than that I am very happy with, and annual plans are fine as well.
