Also important to note that the Android approach is more likely to continue to work. In many places (certainly Manhattan, where I am), everything but LTE (and I gues 5G) has long been turned off such that GSM/Edge/UMTS/etc no longer work.

What? I'd think lots of IoT and other automated data service relies on cheap and less-than-bleeding-edge technology. 3G coverage seems to include Manhattan (and most of the USA): https://www.whistleout.com/CellPhones/United-States/New-York

Cell site visualization tool featured on HN front page a few days ago shows thousands of 2g and 3g sites in NYC

I wonder how this data is collected and how long it takes for a tower to not be be seen before it drops off the map.

Carriers may be keeping a small (relative) amount of capacity up and running, but in the meantime prevent new activations (ATT does this with there 3G network for example), so "coverage" is a bit misleading in many cases.

Oh wow. Various types of monitoring use cellular, house alarms etc.

Are those things just using LTE now?

In the states, LTE Cat M1 is most frequently what's used / available from my experience for IoT. In other places NB-IoT is more prevalent (which is way slower, but also way simpler)
