Their current trackers are 3G only - and most countries are shutting down (or have already shut down) their 3G GSM networks.

What? Some operators are closing 3G networks, but not, I think, "most countries". Frequency allocation is moved to LTE, yes.

But 3G modems fall back to 2G (GSM) which is'nt going away any time soon in most places (yes, there are exceptions), and 2G is quite enough to send location info.

Sorry, I meant 2G - e.g. in Australia, Telstra/Optus have already announced shut-down dates, the third network Vodafone hasn't, but they're expected to soon - which renders the device useless.
