Default 992 PCM Data Connection Issues

Hi everyone,

I recently imported a 2023 Gen 992 Carrera GTS from the UK. When the vehicle arrived, I successfully set up my Porsche ID in the car. However, I ran into an issue where wireless Apple CarPlay wouldn't work.

After contacting Porsche Customer Relations, they suggested resetting the PCM to factory settings. Unfortunately, after performing the reset, I can no longer log in to Porsche Connect. I’m now getting the error message: "Please establish a data connection to use this service."

I’ve tried connecting the vehicle to my phone’s hotspot, but it didn’t work. It seems like the car only has an integrated SIM, which currently doesn’t have a data plan.

Does anyone know how to establish a data connection on a vehicle with an integrated SIM (and no active data plan) to reconnect to Porsche Connect?

Any advice or guidance would be greatly appreciated!

Thanks in advance!



Now unable to connect due to loss of data connection
Is there a way to synch the Connect ID using the cell phone data?

You have to Purchase Porsche Connect service. It's "included" for several years with all the new car purchases in the US so they activate them at the dealer (mine is thru Verizon, not sure if they all are). You may even be able to buy it online if you registered your vehicle's VIN to your Porsche account on their website? Your car's VIN should show up as a tile on your logged in view here: https://connect-store.porsche.com/offer/us/en-US

Thanks for your reply. I do have the following subscriptions.
I was able to connect initially and now it shows that I have no data connection

What country are you in? From the date format it appears that's the European website, and my guess is that plan was set up with a UK carrier and will need to re removed/reinstated for your locality. Here in the US, we don't show data packages on ours (with Verizon).

I imported the car from the UK and shipped it to the Cayman Islands. Unfortunately, there's no external SIM on this car as it is an integrated SIM, so I'm unable to swap the SIM with a local one. I'm still puzzled that the UK carrier worked when the vehicle landed here, then all of a sudden stopped working. Do you have any suggestions on how to swap an integrated SIM? Is it even doable

A beautiful car in a beautiful place! As I understand it, the SIM is not a physical card, it's an E-SIM. I imagine it can re re-coded for any local phone carrier, but you'd need to contact Porsche for how. It is odd that it worked for a while, but it's sort of acting like 'hey you're WELL out of your carrier's roaming range for too long, we're switching this phone off".

My 992.2 currently has a locked-up modem, where it says it has 4 bars of Verizon 4G and receives Sirius XM and some 4G data, but Porsche Connect refuses to log in and map and PCM updates won't work. That's taking a trip to the dealership to reset.
When you did your reboot, was it the reset from the menus or the technicians reboot (two fingers on the upper-right corner)? Didn't help in my case, but its a more serious "reset".

@MAXFPS you're probably right that the carrier probably saw the roaming charges and switched it off. Congrats on your 992.2, that's a stunning machine!
In terms of the reset I performed a factory reset from the menus, as was suggested by Porsche Customer Relations Hub in the UK. Do you reckon a technician reboot will fix the issue?
They're beautiful cars and a dream to drive, but the tech needs a significant overhaul as it is very clunky when compared to the likes of BMW and Mercedes.
At this stage I'm just trying to get the startup screen to immediately load to a default profile as it takes about 2 mins to get past the splash screen as the car keeps thinking that I'm setting it up for the first time every time the ignition is turned on.

The technican (two finger) reboot doesn't hurt a thing so I'm sure it's worth trying, but this really sounds more like you just don't have a cell phone plan and need to marry a new one to the car's SIM. For the technician's reboot, you just lose your profile which you don't have anyway. Seat settings and favorites and everything are evidently all save on the carkey you're using in the vehicle, which is pretty neat. Since my Porsche Connect also won't login, I too get the brand new "Add account/Continue as guest" screen every time I turn on the car. However it's very quick to get to that, likely because it's not searching for a cell carrier that's missing.

PS- is your Emergency/SOS light up by the rear view mirror green? That's the bare minimum connection all the cars should have, and the first question the Porsche tech asked me when I called support about the modem problem. No maps updates you can live with, no SOS in a car crash - that's a fix ASAFP issue.

Hello! I just imported a 2024 911 GTS from Canada to the US and having this same issue. I should have included services but because the car/eSIM is assigned to Canada it will not allow me to even purchase Porsche Connect services even if I wanted to because my billing address is not in Canada, which I find kind of ridiculous

I have talked to two dealerships and multiple people at PCNA and they simply told me there is no way to change the region the car is "assigned to." So I'm guessing your car is assigned to the UK and now because of the way Porsche has painted themselves in a corner the car will never work anywhere else the way it's supposed to via their design. Why they would ever do this is beyond me because all it is going to do is **** off their customers who may have the nerve to move countries for work, family, etc, and render their very expensive car crippled. It makes no sense to me because it doesn't help Porsche either since they won't be able to sell those services to anyone unless the car is returned to its original assigned region.

I find it difficult to believe that Porsche Engineers would ever do something that would castrate the systems in the car, not be able to sell services, and even potentially open themselves up to some sort of class lawsuit or other. I'm hopeful they release some method to change the region assignment for the car, but as of right now, they are saying there is no way to have a fully functional vehicle outside of the country the car was originally assigned to.

It's pretty infuriating having a brand-new car that doesn't connect to the app correctly and none of the included services with a new car function at all because of Porsche's design. The pre 2022 PCM had a SIM and then also had an external SIM slot which gave flexibility and the ability to make it work anywhere. So from what I can tell, Porsche downgraded the newer system to no benefit of anyone, including themselves.

If anyone comes across any fix for this you'd make a lot of people very happy.

I suspect that Porsche do this for regulatory reasons.

the car will have a country code. This will then keep it compliant with local laws ( USA don't allow matrix beam , your turn signals are the rear light flashing no orange etc ) there will be dozens more. The U.K. / eu now require mandatory speed warning and lane departure which in the USA you don't etc etc etc.

whilst it would annoy me Porsche connect it 100% useless in the uk and they have the front to charge for it so nothing is being missed.

This is clearly an oversight and another example of an over-engineered solution. Wireless Apple CarPlay and Android Auto in any new Porsche model depend on an LTI connection through the integrated eSIM to function. In contrast, nearly every other car manufacturer allows Wireless CarPlay to work seamlessly using either bluetooth, mobile phone data or a phone hotspot.

For some reason, Porsche has chosen to restrict this feature to the integrated eSIM, which unfortunately is region specific and cannot be replaced. It's surprising that they decided to eliminate the physical SIM slot altogether. While Porsche builds phenomenal cars, they lag behind the competition in implementing technology effectively.

I actually doubt it because my car had to be re-coded to be imported so that the dash was reading MPH, something with the parking brake light, Matrix headlights, etc. Them updating the region code in PIWIS does nothing for the eSIM. In fact, the eSIM in my car is connecting to AT&T towers in the US and not even roaming. This is just so the SOS button works I think. None of the Porsche Connected services work and won't let me even buy them on the online portal. So basically it's Porsche blocking it on their back end. iPhones, Androids, etc all have eSIM chips now that can be retasked to almost any carrier worldwide so for Porsche to say they put some inferior component in that doesn't have any ability to be reprogrammed seems ridiculous.

My Apple Carplay does work in my car and suspect Android auto would work too. Nothing else works though.

Either this is a complete fumble by Porsche engineers or it's an intentional tactic by Porsche that has seemingly no benefit to anyone, including them. BMW, Mercedes, and plenty of other manufacturers don't have these issues if someone has the nerve to move. Pretty frustrating.

Either way it's very frustrating as I can only run Apple Car Play via a wired connection and none of the Connect features are active.
Whilst the car does show a green light by the SOS button, which means it is picking up some sort of a signal, Porsche Connect UK confirmed that because the vehicle is a UK reg car and that the car is now in the Cayman Islands, the car won't show a carrier data signal unless it is shipped back to a dealer in the UK! Not a feasible solution imo.

That's strange it won't let you do the Car Play wirelessly. I can do wireless on mine but took a little messing around before I got it to sync up correctly. You might double-check the directions because the wifi of your phone has to connect to the car because there is a lot more data being shared with Car Play than just a standard Bluetooth connection. That's how it works on my BMW X5 system as well.

The not-so-funny thing is that apparently even if you did send the car back to the UK there is no way they can code the Porsche Connected services to work in another country with the eSIM. The Canadian Porsche dealership I got my car from looked into it because they are awesome and wanted to help but the issue lies on the back end of Porsche's services and the eSIM. I feel like there is a high probability the idea it is "impossible" to correct this in'ts true, but PCNA is unaware of any fix and have no indication a solution is in the works.

To me, this could end up being a lawsuit (possibly even class action) if someone with the right motivation wanted to push the issue. Buying a $200k car in one country where those systems and services were part of the selling points and then none of the systems working correctly anymore because you had to move for a job (or anything) to a different country with no ability to update the system to work properly seems like potential unfavorable liability towards Porsche.

In all cases, I think everyone can agree it is pretty deplorable how inflexible the system is. All people want is for their car to function the way it was advertised regardless of whether life takes them and what country they live in.

With any luck, they'll come out with an option to fix this before it goes down that rabbit hole.

Wait, you're in the Cayman Islands and you didn't buy a Cayman?
