I paste this in every time there's talk about cheap data SIMs for IoT stuff: https://www.truphone.com/us/consumer/sim/ https://www.truphone.com/us/consumer/sim/ I'd love to hear other people's experiences, but basically: $0 a month per SIM, $0.09 per MB. Since there's no monthly fee, you're supposed to use a certain amount of credit per month or they'll charge you a small fee to keep your number active, but mine has been unused for maybe six months with zero charges still. The SIM costs $30, but half of that is service credit.
