Is there a word or phrase that describes a prepaid SIM for a data plan, that doesn’t have a monthly fee, but is just a metered cost? I want to buy one of those but I can’t figure out how.
“Prepaid,” in the US, seems to mean “a monthly plan where you pay a fixed fee in advance,” rather than “you load it up with 5 GB of data for $10 and, when that’s used up, you can pay for more data if you want.”
