I think we already shut down most of the 2G and 3G in the USA, so those would already be offline here. It happened to my (gas) car already that was using the 3g network for its OnStar type service. But I had already disconnected it myself so it didn't matter
3G still exists specifically for stuff like this (though more for remote monitoring devices, since this is a consumer device requiring a consumer account, it doesn't work).
It's just that as a consumer, you can't buy into 3G - there's no way to get service on 3G.
One car in my family is 3G only, and reports a cell connection everywhere we go (it just can't use it).
The oil/gas/pipeline (water) sector uses 3G monitoring devices all over the place.
I had one of the first OnStar versions that used a 3-watt analog cell connection (this was when cellphones were 0.6w on the high side). Damn thing had coverage in the middle of the west Texas desert when my cell phone couldn’t even find a tower for miles.
