Using SMS as the control protocol seems like a bad idea. You are generating evidence with each command sent that may or may not be stored practically forever by the telcos.

That is valid for any centralized service in general. Fun fact: I am working on something in that field in my spare time(whenever I have both time and motivation) and I opted for LoRa instead specifically for that reason, even though it comes with a wide range of limitations: payload, range is determined by line of sight, no multiplexing and all that. But did make some real world testing late last year and the range I got was REALLY impressive. Easily 20% above what the manufacturer had put in the spec sheet - 12 and a half kilometers with an off the shelf dev board.

Note that SMS is the protocol advertised to buyers but the unadvertised login credentials for the web portal let you manage the device without SMS
