This might be a crazy idea but I am wondering if anyone thought about this.
Pagers are almost extinct nowadays but pagers services still available (as long as doctors are around).
Wifi/LTE/3G/4G have many advantage over a pager service but a pager service is cheap, reliable, and signal travels far more distance. So I am wondering if anyone thought about sending data though paging service?
To be clear, I am not looking send big data, maybe for sending small data, (like pinging or beacon system).
Any thought or information? I think this might be a interesting project.
