This is independent of a cellular carrier, you use unlicensed ISM bands for communications. You can sort of think of this as very long distance Wifi. The sensors communicate with a separate base station that you configure. The Datarates you can get over this are somewhat dependent on the distance between the sensors and the base station, so it’s good for transmitting data, not good for web pages. I haven’t used it, but I’ve spent 6 to 10 hours looking at it.
