2G +3G Shutdown - Impact On Car Comms, OTA and eCall?

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:
  • 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 ☹

I think you have answered your own question by the quotes in your post, so I am not really sure what you are asking....
Everything produced after 2019/20 onwards is almost certain to support 4G. 5G has been in use with mobile operators for years now.
The first G1 was analog and G2 (digital) was introduced in the early 90's, G3 came along in the early 2000'S and 4G was introduced around 2010. 4G started to be used in the UK around 2012/13 so I don't think that a lot of "new" forecourt and brand new cars will have anything less than LTE/4G connection.
5G was made available since 2020....now the coverage is a different subject. However this is improving rapidly...I have 5G signal on my phone INSIDE the house and we are not in a "big" urban area, I would say quite opposite in fact.

probably because the expected useful lifespan of a mobile phone is at most 4 years before the hardware is struggling to keep up with ever-less-efficient software requirements and more stringent software vendor's hardware requirements (e.g. Google insisting on ever-more-secure boot and secure enclave stuff). The expected useful life of a car is 10 years or more. It's probably good that car manufacturers are a bit more cautious about putting fancy new features in the car's systems.
That said, I normally try to keep my mobile phones in use for about 5 years or more between upgrades, unless there's documented issues that would put my personal data at risk by using old hardware.

2G can handle voice and data, but not large amounts of data, so it's useless for the modern web browsing, audio or video streaming.
It should be sufficient for the sort of telemetry that manufacturers might use, which is a few statistics uploaded at the start and end of a drive.
eCall is rather pointless, unless there's a collision that has utterly incapacitated all people who might otherwise be able to call for help or incapacitated any mobile phones they may be carrying.
It would be interesting to see stats from emergency responders to see how many automated e-call activations there have been across Europe that weren't also called in by regular 112/999 calls.
'remote control' via mobile phone app to see state of charge, activating climate control also needs very little bandwidth, but it does often rely on manufacturer's back-ends that are often very flakey, and almost always will go via the manufacturer's servers and over a flakey cellular network rather than directly via a local wireless connection (bluetooth/wifi).

Your faith in EU regulations safeguarding the interests of consumers is touching, but entirely misplaced.

The EU has known about the 2G/3G switch off for years, but they didn’t get around to publishing the required specification for 4G/5G ‘next generation’ eCall until LAST YEAR (EU 2024/1180)

Meanwhile existing EU regulations require car manufacturers to continue fitting cars sold in the EU with 2G/3G comms until 2026

And?? Why did you started this thread if you know EVERYTHING about it? Once again, I don't really understand why you are asking question that you already have answer to.

My 74 plate Smart #1 Premium for example is 4G, so what about the EU regulation you are talking about?
My 2020 BMW i3 was LTE connected, so this is the band between 3G and 4G.
My 2020 Tesla M3P was on LTE as well....
I honestly don't think that you will find any car produced past 2022 to still using 3G and don't even think about 2G.

This is from the Smart website:

"Over-the-Air updates keep your smart up to date effortlessly. When a new feature, fix, or software update is available, you’ll get a notification on your smart’s display. Simply download via Wi-Fi or 4G and install when it suits you. Stay ahead with the latest technology and enjoy an even smarter driving experience."

For most EVs I don’t think it’s anywhere near as big an issue as you may think @EV02

As said above, pretty much all cars that have been on sale here for at least the last 7 years or so will have LTE/4G capable radio modules fitted to their telemetry/SOS systems e.g my old 2017 Tesla definitely had LTE comms with roaming SIM fitted.

All the newer EVs I’ve owned since have similarly been fitted with 4G/LTE radios.

Thanks for your factual information
Nevertheless you “think” a lot of things, Padrino, that you don’t know.

My OP asked for factual information:
“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?”

You have helpfully provided factual information about 4G/LTE car comms for your Smart, BMW and Tesla, but do they also apply to eCall? (EU regulations requiring 2G/3G are still in place)

And just because Smart, BMW and Tesla have been ‘ahead of the game’ installing 4G+ for several years now (which they should be, given their premium prices) it does not mean that all other, less premium, manufacturers have also been doing this. This is the information I was hoping could emerge in this thread.

And the most useful Skoda table you provided confirms that cars will lose connectivity services well after the “2020” construction cutoff date you previously asserted in your first post, and that eCall (listed as “Ongoing“ or “No remedy” for all Skoda models) is a total EU omnishambles

3G and 2G retirement is a global thing, driven by the mobile telcos wanting to gain more bang for the buck for the spectrum they have bid on and freeing up and retiring redundant / less remunerative mobile standards that inhabit spectrum they could otherwise re-farm.

It’s really not anything to do with the EU per se.

In Europe it has EVERYTHING “to do with the EU”

for eCall, it is a total EU shambles caused entirely by the EU

the EU made the regulations requiring 2G and 3G comms for eCall even on cars being built now

those rules are still in place for vehicles being built today, despite the EU knowing full well that both 2G and 3G are obsolete and being phased out - 3G has almost completely gone already

and @Padrino has confirmed all of this with the helpful Skoda table he kindly posted

* Inster Owner Handbook: “The mobile network operators will phase out the 2G and 3G in many countries around the world… and therefore beyond the control of HYUNDAI... (therefore) the automatic/manual eCall will no longer be available in the event of an accident or a situation requiring an emergency service


Stellantis
  • Peugeot E208 up to 2022** or later? (eCall possible permanent loss?)
** @hsvt225 post


Dacia
  • Spring up to 2027*** (eCall permanent loss)
*** @RolandButter post


Comment
So, just to recap, @Padrino has provided a most helpful table from Skoda listing models (some less than 1 year old and 2 models still being manufactured) where comms will cease to work when the 3G+2G shutdown is complete and there is ‘No remedy’ or no solution yet. These cars are not old and were built when the shutdown was already known +fully understood. Most concerning is that Skoda is continuing to build cars with obsolete 2G/3G comms until June 2026, and new buyers may not be being told this.

Further information provided by members about other manufacturers and models can be added to provide a more complete picture.

2G shutdown is a long way off in the UK at least (early 2030s by the reckoning of most networks), which really is the concern for the majority here for SOS calling functionality. There’s very little (totally zero actually) any of us can do about it, including shouting at clouds.

Otherwise as said for data connectivity most cars since the mid/late twenty-teens have had 4G/LTE connectivity. 3G shutdowns are already in play, and those car owners affected by it, already know it.

This is correct

2. “3G shutdowns are already in play and those car owners affected by it, already know it.”

This is NOT correct:
  • see Swedish link posted by @RolandButter (above)
  • my own (anecdotal) experience buying an EV: eCall was demonstrated but nothing was said about it ceasing to operate after 2/3G switch off (this is buried inside the 500+ page Owner Manual)
3. “Otherwise as said for data connectivity most cars since the mid/late twenty-teens have had 4G/LTE connectivity”

but many don’t (see list being compiled)

4. “2G shutdown is a long way off in the UK at least… which really is the concern for the majority here for SOS calling functionality”

This is NOT correct. If your family member is in an accident involving no other vehicle and leaves the road then, without 3G, eCall CANNOT send precise location data, meaning delays in emergency services locating the vehicle which may have serious consequences for your family member(s)
