LoRa (from “long range”, sometimes abbreviated as “LR”) is a physical proprietary radio communication technique.[2] It is based on spread spectrum modulation techniques derived from chirp spread spectrum (CSS) technology.[3] It was developed by Cycleo, a company of Grenoble, France, and patented in 2014.[4] In March 2012, Cycleo was acquired by the US company Semtech.[5]
Use LoRa instead of sim cards so they can’t tell who bought it though
If one lives in an area with tons of LoRa enthusiasts, this might work exceptionally perfect.
