1, Thé 2G shut down was announced a year ago and my iPhone 4S still works but I know it will stop soon because ATT gave all 2 G users free iPhone 5’s.
2. I have a 2018 JLR product too. I will say that last year my hotspot module stopped working and they replaced it under warranty and it works fine.
3. 3g is not going anywhere.
4. Talk in person to other 2018 owners for yourself. JLR is not gonna just let their cars fail. I bought a X -type in 2001and I had the built in flip phone put in with no GPS. When the government shut down all mobile phones without GPS; Jaguar gave me a full refund and took the phone back.

3G has been discontinued in most of the US market (although some pockets still exist) by all three major carriers (AT&T, Verizon, T-Mobile). If it is still working in your area it will soon be shut off as all carriers have pledged to sunset the technology by the end of 2022.

Here is the announcement from the FCC themselves:

Quick update on mine... it looks like there is actually already a 4G modem in the MY2018, dealer went through a number of steps to resolve the TCU issue (seems like a firmware issue) and then replaced the SIM and now the car is connecting via 4G. Just to confirm - system is the old 8" ICTP system with buttons on the side (so no CarPlay):

 

Also trying to deal with my 18 not having its internet connection working right for the nav system, which I finally got around to. Jaguar support couldn't do anything because they were having issues remotely accessing it, so I took it into the dealer. After yet another headache of an experience with the dealer (which is another story), they say there's something wrong with the TCU, but they were told not to replace it, instead they need to send it to Jaguar Engineering. Given that the car can't be used without the TCU, we scheduled a day for me to leave it with them for a few days so they can do this.

Not sure how mine is different than ScottT's issue, but we'll see. Just another headache for something stupid.

 

Super interesting - that's exactly what I thought was going to happen to mine after what ViperX100 said above with having his TCU sent off, I was very surprised when they didn't seem to need to send it off at all. It was in for 3 weeks but that was for replacing the Body Control Module, Gateway Module and Tailgate Control Module for other issues (BCM was shorted). TCU issue was fixed about a day after I dropped it off. I do see the tech notes that it's a fix pending a "permanent fix", so I'm not too sure what's happening behind the scenes...

I kind of wonder if they changed the TCU hardware half way through the MY but I'd be SUPER surprised if they did that, I assume it's the same hardware. In which case it's maybe just the dealers inconsistently dealing with it...?

 

It better not take 4 weeks. They said "2-3 days", but do I trust what the dealer says?

Of course, that Jaguar facility is only 15 minutes from me, so if necessary I'll go sit in their lobby until they give me a working TCU back.

 

It took 4 weeks for me... Painful

 

Haha, that's quite a funny image for some reason.

I wonder if the manual patch file mentioned by my tech came out after ViperX100 took his in? That and the "until the permanent corrective action is delivered" from JLR suggests a still-evolving situation to me. I wouldn't be surprised if they started getting a few TCUs in for replacement and figured there has to be a cheaper way to fix it that doesn't involve shipping all of the TCUs back... I'd hope they did!

 

I took mine in in early June and got it back in early July so unless they got a new patch since then, I wouldn't count on it. They had to ship the 3G unit to New Jersey to get updated.

 

If someone at Jaguar things its OK to keep a customer's car out of service for 4 weeks because they can't get an internet connection to work, then I think that's a really good indicator of Jaguar's future, or lack thereof.

When the car goes in, they've got the week (5 days) to get it resolved. Shouldn't even take that long.

 

Well, got the car back today, so it took them 5 days (brought it in Monday morning). The sent the TCU to Engineering to get it updated and they replaced the SIM card to make it all work properly. Apparently it took an extra day because Engineering apparently had Wednesday off (have no idea why). I did have an advantage because I (and the dealer) are so close to engineering that it was hand delivered and didn't have to be shipped.

So, for suture reference, it is fixable and it doesn't take that long to get it done.

 

Anyone have any additional updates on getting TCUs replaced with new versions compatible with 4G?

I just had my 2018 in for annual maintenance and had them check to see if the TCU was compatible with 4G. It is not. Mine has TCU2 which is only 3G. I asked if it could be updated. They said it can't be updated.

I am not sure I buy that. It seems that others have had their TCUs updated. I am trying to get this taken care before my warranty runs out next year.

 

Hmmmm, I would reference the work notes I pasted in above (post #24) where the dealership originally thought they'd have to replace the TCU in my 18 but then when they submitted a case for the TCU replacement, it was rejected noting that a manual patch was available that could be applied through a recovery software update which then (with a replacement SIM card, mine might have been faulty) allowed the existing TCU to work via 4G. Worked flawlessly ever since

 

I plan to. Do you know the build date on your car? Mine is a May 2017 build.

 

Yeah mine was April 2017 so I'd be surprised if yours had an older TCU

 

My '18 had a March 2017 build and had the 3G SIM card. When it stopped working, I brought it to the dealer and they replaced the SIM with a 4G one (and had to reset my InControl account) and it worked fine. So I would have the dealer check again.

Also, the real weapon here (at least in the USA) is the Terms & Conditions of the InControl services, which no one ever reads (attached). If you do, you'll find this little gem in section 13.6 (emphasis added):

13.6 In the event of a discontinuation or change of necessary telecommunications systems and services (e.g., if the Network Provider sunsets, terminates or restricts wireless services of the type used by the InControl Services and/or your Vehicle), you are solely responsible for replacing, as well as for the cost of replacing, any equipment that is necessitated as a result of such change or discontinuation, except if such change occurs during your Vehicle’s base warranty period, we will, at our sole option, either: (i) obtain substitute and reasonably equivalent network coverage compatible with the existing InControl Package in your Vehicle; or (ii) install, remove or replace any equipment that is necessitated to make the InControl Package in your Vehicle compatible with then-available network technology unless neither option (i) nor (ii) is possible on commercially reasonable terms. In such event, you will be solely responsible for contracting for a Data Plan for your Vehicle upon the completion by us of either (i) or (ii) above.

So if you are still under your base warranty (and that's been confirmed by the dealer as many cars get 'punched' in the system when they arrive at the dealership vs when they are sold), then Jaguar is on the hook to fix it.

 

Thanks! I will be including that in my correspondence on this.

 

I contacted the dealer on the issue. I informed them that contrary to what I was told by them older TCUs can be updated and/or replaced. The dealer indicated that their shop foreman would research the issue and get back to me. I offered to provide a copy of a service work order detailing an older TCU that had a software update performed to allow it to work with 4G. They did not indicate if they wanted to see it yet.

The dealership contacted Jaguar and provided them with my VIN. Jaguar indicated that all 2018 F-Types were built with TCU3, which is 4G capable. They then asked what issues I was having.

I actually was not having any issue as I had not used In Control for a while and had not even installed the app on my current phone. I was thinking of reinstalling the app and using it again but since my car was about to go in for annual maintenance I figured I would have them check it out as I was not sure if my car had 4G capable hardware.

It turns out my car is fine. I installed the Jaguar app on my phone and everything works as it should.
