I work for a company that uses sensors with some kind of 4G connection. I don't know the details but I did ask our sensor guys what would happen if someone removed the SIM card (or whatever it is) and started using data. My recollection is that locking down those SIM cards is the responsibility of the sensor maker. We have an agreement to pay for all legitimate traffic at a contractual rate, but the device manufacturer actually owns the connection and pays for the data themselves. So you're probably using the connection in violation of the wishes of the responsible party, but it was not clear to me exactly how illegal that would be? Like I'm sure they could charge you with a crime but I have no idea what it would be.
