Lawrence points to an interesting "datacenter":
This seems like a story that should have gotten a lot more attention than it has. “Secret Service Dismantles Weaponized SIM Farms Designed To ‘Shut Down’ NYC Cell Networks.”Hours before President Donald Trump’s address to the United Nations General Assembly, the U.S. Secret Service announced that it had dismantled a massive, decentralized SIM farm network, just 35 miles from New York City, hidden inside five abandoned apartment buildings. The telecommunications stealth weapon was capable of paralyzing regional cell networks through denial-of-service attacks.
My first instinct was that this was a State Actor prepping some sort of cyber attack. Now I think it's a Phone Spam datacenter:
SIM farms allow “bulk messaging at a speed and volume that would be impossible for an individual user,” one telecoms industry source, who asked not to be named due to the sensitivity of the Secret Service’s investigation, told WIRED. “The technology behind these farms makes them highly flexible—SIMs can be rotated to bypass detection systems, traffic can be geographically masked, and accounts can be made to look like they’re coming from genuine users.”
Bastards. 95% of all the calls I get are along the lines of "You have been pre-approved ...". I don't even answer a call where I don't recognize the number anymore.

I will answer calls from local area codes. Some have been spam but most are legit for business or medical stuff. I don't know the mechanism behind my phone labeling calls possible spam; I let those calls go to voice mail and most don't leave any.
