TCU (Telematics Control Unit) is frozen or locked due to the continent/region change USA to EU

Best of luck. Let us know how you do. The dealer in Denmark has specialized in importing and reconfiguring the lightings and Rivians.

Thank you very much.
Either way, I believe I may need to come there in person. Thank you for the information, and I will update you with the results once I finish my attempts here.
If I’m not able to resolve it myself, I will come to Denmark. I will contact you privately, if that’s okay, to get more information about the place and to arrange an appointment

To do this, it requires more than programming. From convos I have had with people much more knowledgeable than myself, the TCU needs to be converted from ESIM to SIM on a bench. I know a guy that does it, but he is not on this forum. I believe he is in Poland. You would need to remove the TCU and mail it to him and he mails it back. If you are interested, I can ask him for an email address so you can speak to him directly.

I am not sure how this will affect the data on the server and future updates via OTA or FDRS. I would assume since it is the same part number and firmware, that it would not cause issues, but I cannot say that for sure.

But after 30min, when vehicle turned off, modules, especially tcu goes sleeping and will not response till you don't start the car. If car charging - tcu not sleeping. You can't woke up via sms or calling, so this method not so useful.

Thank you for the explanation. I understand the limitations of the system.
My goal is to have the truck fully functional in Europe, especially navigation, which currently does not work since the vehicle was imported from the US.
Also, the vehicle has not received any OTA updates since I brought it from the US, which I believe is related to the regional TCU/APIM configuration.
Remote wake-up is not my priority — I mainly want working navigation, OTA updates, and stable EU functionality

If your EU TCU will not work, you can use method with replacing esim to Sim for your needs with OTA, it's easy, you need sim adapter (1$ on aliexpress), sim card, eject esim (the most hardest part), solder new sim adapter. It's not cost 100+$ which some clowns took for this job, so you can go to the local workers who repairs mobile phones or laptops and asked about this replacement
Esim must be ejected, on photos showed which pins used
Pin should be removed from Sim, and you need have internet package (traffic) on your Sim in tcu

Thank you very, very much. Honestly, as it looks right now, this seems to be the best option.
My only question is whether reprogramming would still be required after converting the TCU from eSIM to physical SIM.
Thanks again, I really appreciate your help

Nope, no any programming or other stuff after sim replacement (if we talking about factory tcu from USA with replaced sim). But I recommend to try replace tcu from EU vehicle, if it doesn't help, then return back your factory TCU and replace Sim.
Adapter https://s.click.aliexpress.com/e/_EQnGne8
And a bit more photos with replaced sim
Not my work)
And some electricans used ground from another place on the board, but it doesn't matter using it from place with my wiring diagram or from those which on photos below

Thank you very, very much.
On Friday I will receive the EU TCU and I will test it to see how it goes. After that, I will update everyone here with the results.
I truly appreciate you and everyone else who has shown willingness to help me with the issue I’m having with my truck. If it weren’t for you kind and helpful people, I honestly wouldn’t have been able to move forward with my truck at all.
Thank you all again — I’m very grateful to every single one of you

It occurs to me that your issue isn't any different than if you had imported a late model ICE F-150 (14th generation). There is a sister forum on here that has many more vehicles and members - maybe they have looked at this as well (unless ICE F150's are just as rare as Lightnings in Europe).

I can't say whether or not it actually is different or not, but I suspect it might be, aren't the ICEs more locked down than the Lightning? Either way I always suspected that putting your own SIM in might work, I just thought I'd never see one done. I love it.

According to a link in the Comma thread, TRON came to the ICE F-150 in 2024. And his is a 2022 - lots of those on the ICE forum that use many of the same parts as a 22 Lightning.

Oh, btw for the navigation to work you will need another module to be replaced in addition to the TCU if I remember correctly. The swedish mod seller has that one too available on their web shop. But you can also just use better navigation with apple/android auto.

I have already replaced the eSIM with a physical SIM card.
The problem is that the system is still throwing DTC errors, and I’m not sure how to clear them.
As it looks right now, it seems that some parameters still need to be changed or adapted somewhere, because without touching anything else, it’s not working properly.
If anyone has experience with this or knows exactly which parameters/modules need to be adjusted after the SIM conversion, I would really appreciate the guidance.

It's common issue, and it's dissappear after few weeks, or even if still be present - doesn't matter, it does not affect.
Did you reset TCU connectivity via Sync menu?
And after that add vehicle again in Ford app

Yes, I already did the TCU connectivity reset through the SYNC menu.
I also removed and re-added the vehicle in the Ford app.
At the moment, the TCU still has no internet connection.
If it’s normal that the connection appears only after some days, I’ll wait and monitor it.
I just wanted to confirm whether this delay is expected or if there is anything else I should check.

Do you have a photo of how you soldered your SIM card? Also, do you have a photo of the sync screen in the connectivity menu? It should say 4G there.
Also, remember that the SIM card should be password-free and have internet traffic (paid package, etc.). Common problems with no internet on the TCU include poor/incorrect soldering, poor contact between the SIM and the adapter, and the network operator (yes, sometimes it is worth trying another SIM from a different operator). There were particular problems with duplicate SIMs (duplicates of the main number). And does a call go through to your number, the SIM in the TCU?
