Model Year 23/24 E-Sim

[jamieformentor]

I have seen discussions around the e-sim and whether we can choose our provider (the whole point of an esim) but there was no concrete facts; just opinions on if this was possible

Cupra dealer said its possible but refused to say how.

I would use cubic if prices where sensible! I can buy a portable wifi hotspot and have a years unlimted 5G data for a few months of cubis cheapest data pack!

Cubic was suppose to run slow as well. They might have changed it. They probably have bought slow bandwidth or something at a cheap price. Something to test. That's the story.

E SIM is just a replacement of physical SIM and nothing more.
Where as to choose a mobile operator it should be allowed but unfortunately it is not.
Cubic is an operator but more like MVNO / MVNE which uses local mobile operator resources mainly.
Cubic seems to be the choice of operator by VW group maybe other brands.
So in UK cubic would be using any of the local operators to provide signals / mobile networks connection by using likes of 3UK Vodafone etc.
In other countries their local operators.
There should be options given to customers just like normal mobile contracts if I want to change the operator I should be allowed port in and port out.

Evidently not. These are like the data mobile contracts you get in Japan, throttled. So they go through a very fast operator and get throttled. Like buying a low data BT fibre rate. So expensive and slow to the user, cheap to them. The slow bit that people have talked about before.

Ok let me try to explain you are correct this is data only sim.
But it works exactly similarly like your sim in mobile.
From network point of view it's no different. It has a phone number etc. But just limited you can't make or receive calls or sometimes text.
It depends on Cubic what sort of contract they have in place with the local mobile operator or operators.
5G will always be 5G, 4G would always be 4G.
So data restriction is what cubic and local operator have contract it depends on that.
Search IOT you will get more insight.

Indeed it's said it's throttled which is worse. They buy data cheap sell it expensive. When abroad I buy cheap Japanese data but they use a network which runs much faster (cheap to me). When demand isn't high on the network its as fast as a normal 4g, but when demand is high they throttle the cheapskate customers (that selling off bandwidth has a name). Giving priority to those that pay more... normal rates. Cubic so the story goes throttles the data the same .

You won't be able to change the esim bit since that is how it is unless the hacking of mib3 has taken off. Someone might have done it but all hacking is done on a workbench like early mib2 so you'll be stuck with high cost cubic, slow speed via the esim.

Softbank... hmm network I use in Japan. Basically Cubic makes money by buying cheap, selling expensive but for some 4g operators they sell cheap as well.

It's a business model. Has some weird settings in the Japanese one of it as you pickup the card from hotel reception or collection point and work out the commands you put in the tablet. No money will be returned if it doesn't work say the instructions. Japanese business practice. So far, so good.

Better off using a hot-spot with your own data sim in the UK. I buy Amazon EE data sims for my tablet in the UK and bin the sim each year. Currently £63, 120gb a year. People get hot bothered about these cards but they are really tasters, keep the card and pay normal EE rares or bin it and buy cheap.

For Cubic you don't know what it might cross subsidise in the platform or just a little money earner. If I had mib3 I'd just hot-spot onto my annual disposable EE sim.

It's these parameters I fumble with after a 12 hour flight to get these services.... which have a name working on my device

Basically the esim in these cars will be piggy backing on a well known network we recognise, but they have bought cheap bottleneck data. It's demand pricing, fixed to them variable rates to the user. The data rate is reduced in busy times. They would claim you are only getting the data you need. Whether it's IOT I pass, like AI banded about. Go back to first principles .

These MVNOs buy in bulk or I say contract from main operator.
Then they charge us a customer.
Ethically it should be value for money for us as a customer.
Which is not.
And yes removing the SIM slot or even not able to manage the E SIM is a really bad idea.
It's like you have a mobile phone and you cannot change SIM as per your liking.
Probably in future they might use a basic common sense VW group including other manufacturers to give control to user who paid for the full product but still locked out of it.

MVNO were the initials I was looking for. The E SIM will be closed off for normal customers protecting the VAG income stream and licences if any. The mib enthusiasts as I call them may have hacked that bit but all their work is on the bench these days, not in car toolkits unless Github reveals anything. Where they get placed.

The in car toolkits using the SD card slot rode on the back of an open door they accidentally left on POI import. That got wacked shut when POI import was taken out of the mib3 spec. The encrypted SLA1 signature checks that are normally made on software import were not being made on the POI exploit, so the writers of this code ditched all the SLA1 signature checks and recomputed the metachecks. All clever stuff. I'm told by our retrofitter friends that mib3 changes can be made on the bench with the laptop. The hobbyist enthusiasts made a better job on mib2 of packaging these tools than retrofitters which you'd expect.

So yes it's probably a case of never saying never on fiddling with the esim but not available to the average driver.
