Is manufacturer information available about how these two shutdowns (3G happening now, 2G to follow later) will impact individual models of existing /used and new cars (i.e. cars in showrooms/on forecourts now!) by date of manufacture and VIN?
For example:
As I understand it:
Some of these car comms systems are ‘nice to have’ but eCall is a potential lifesaver:

For example:
- eCall
- OTA
- in-car diagnostics
- ‘remote control’ (eg from iPhone)
- Digital Key etc
As I understand it:
- 3G can handle data, calls +texts and it is being shut down now
- 2G can only handle calls+texts but it will continue for a few more years
- this means that eCall operation may become patchy (eCall has always relied on 2G as well as 3G for good coverage) and cease altogether with 2G switch-off
Some of these car comms systems are ‘nice to have’ but eCall is a potential lifesaver:
- from 2018 the EU mandated that all new cars must have the eCall system using both 2G and 3G
- from 2026 EU has mandated that all new cars must have eCall using 4G
- as already mentioned, 3G is now being switched off (which may cause some existing car data services to stop working) and the 2G switch-off will follow in the next few years
- without 3G eCall may not work everywhere (reduced national coverage)
- and when 2G is switched off altogether eCall on many existing cars will simply stop working ☹

Automotive OEMs must prepare for 2G/3G switch off: eCall specifications have been amended, and a deadline is looming - Wireless Mobility
The mandatory introduction of the eCall system for European road vehicles in April 2018 significantly improved road safety, but the phase-out of 2/3G networks means that automotive OEMs will need a new type of eCall module. New EU regulations supporting emergency calling on 4G and 5G networks...
