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.
