Try Sceptre 65" 4K UHD LED TV, or Samsung QB65R. I have started to see first industrial then consumer devices with embedded SIM cards towards the end of 2000. They were soldered in, now mostly socketed. To access them, the device had to be disassembled, and connect SPI header. No average consumer will think to or able to disable or avoid using that.
