SIM in Car Stopped Working

I have a SIM card in my car that has been working for at least a year.  However, about 3 months ago the data stopped working.  If I move the SIM to a phone then everything is working.  Moving it back to the car and I get no internet connectivity.  The car company (Land Rover) manual says to check with mobile provider as some devices are blocked from service.  How do I find out if the SIM is enabled for cars as a device?

Hi ​@Mike Baker,

Welcome to the Community!

Unfortunately we can’t guarantee that a SIM will work in devices other than 4G handsets.

If the SIM is no longer working it’s likely that we don’t support it.

Does the car support 4G or is it 3G only?

Hi

 

Car supports 4G and it has worked for more than a year.  Just recently stopped (2 to 3 months ago).

 

Any help gratefully received or I will have to get a new SIM.

Hi ​@Mike Baker,

You can certainly try a replacement SIM to see if its a SIM issue.

If you require a replacement SIM you can collect one from your local Curry’s store or by contacting the Live Chat Team.

You’ll need to activate the SIM via your account once you have it.

The SIM works fine when I put it in a mobile phone.  I just has stopped working in the car which is strange as it worked for the first 6 months.  I did get some feedback that it the cards can be enabled for certain devices and it’s possible the SIM has been disabled to work in a car.

 

I don’t seem to be able to get that fixed.  If anyone has any ideas, let me know or it looks like I will be cancelling the card at the end of it’s 12 month contract in a few weeks.

 

Thanks

Duly noted you’ve mentioned the device supports 4G, but see if there’s a setting on their device where you can set it to use 4G only (or to be sure ask JLR) - I’ve helped a few others out with their mobile routers not working and by setting it to 4G only theirs all worked fine on iDM.

 

My gut is telling me the SIM might be dropping to 3G and that won’t work. Your phone might be clever enough (or is already set) to use 4G only.

Thank you for your reply ​@Mike Baker 

 

If the SIM is working in a device, it does rule it out as being a SIM issue. 

Unfortunately, with us not being able to support the SIM outside of our compatible handsets, we would be unable to troubleshoot the issue when using it in a car.
