The cost is probably still too do prohibitive to do so. I worked with IoT devices, generally the cost per GB of data is around dollar per GB. I doubt you would make that back in advertisements. Also, there is cost per SIM so you wouldn't want situation where SIM is active if you don't need it which is why alot of IoT devices have you setup with a phone because they turn SIM on when you sign up for their plan. If consumer never puts TV on Wi-Fi network or cooperates with the phone, then you would have keep each SIM active and turn it off when it checks in via Wi-Fi. My guess is cost is not worth it if you get 98% cooperation. Write off 2% and call it a day.
