I'm working on a leasing project and need to remotely shut down systems if clients don't pay. I need a cheap switch with a SIM card that I can text message in order to shut down the power once clients are late with payment. The switch needs to have a SIM card slot as well as connections for 110V current. It needs to be small enough to fit inside the system so clients can't cut it out of the circuit and have a working system without paying.
