Starlink’s plans vary between markets, but in Australia they have a dirt cheap ($8 AUD per month or something) standby plan that gives you unlimited data capped at something like 500Kbps. If you’re going on a trip and need faster data, you can upgrade to a bigger plan for the rest of the billing month, charged on a pro rata basis, and then revert to the standby plan afterwards.

I used to use Inmarsat BGAN. BGAN would top out at around 250Kbps on a good day, and cost a few bucks per MB on a terminal that cost almost ten times as much as a Starlink Mini.
