Ye of faith.
Use your imagination. I doubt you have millions to loose.
just one scenario:
A hi value corporate target wont have their home alarm system active while in the shower and their cell phone will usually be locked but not physically protected.
Breaking and entering to obtain the sim card from a hi-value target would allow a '
sim swap' to crack two factor authentication of highly secure networks.
The phone could be replaced before the person is out of the shower.
Simpler options are perfect timing for just grabbing the keys to your van and taking off with your van.
The smart water meter data is also transmitted in there. The utility can alert you when they think you have a leak.
One can establish a reliable pattern for when a valuable target is not at a particular physical address without having to physically observe. Like say a gated estate.
For example to serve a search warrant to a person whom is know to be armed and potentially unstable,
or for corporate espionage reasons.
These types of targets are not your typical 'post everything on social media' types.
Other possibilities are sending a kill signal to an entire block to spoof a power outage.
