eSim and calls from/in the car
I have my eSim connected and my iPhone is linked to the car and the eSim.
When I call someone from the car using the voice activation, the car makes the call and the screen says they are calling the person "via Personal eSim". If I dial the number from the screen it says the same thing. If I call that same person from my iPhone, it says they are calling this person "via XXXXXX's iPhone. I am trying to find out if this is normal behavior. I would assume if you call from your phone, and the eSim is connected and linked to your phone, why would it not use the eSim and say, calling "via Personal eSim. I know the eSim is working because I can call from the car without my phone, but when I use my phone it does not go through the eSim. Can anyone that has the eSim connected please confirm how their phone works with the eSim? More clearly put, the question is, when you use your iPhone to make a call, does the BMW screen say you are calling "via your iPhone" or "via your Personal eSim" assuming you are connected to bluetooth and your iPhone is linked to your eSim in the eSim menu.

hm... there is one possible explanation:
there is a thing called SIM-Access-Profile. the connected phone kind of transfers the "sim" to the car that then calls. maybe the car can't handle two virtual sims. it would be interesting if this is the same if the eSIM is deactivated or how it behaves elsewhere. |

My understanding of the esim is that it is not a separate number but a synchronization with your cell number. If that's correct calls from the esim will always show the cell number. My further understanding is the numbers created by setting up esim would not allow calls in to those numbers -- callers would have to use the cell #.

What actually happens is, the eSIM does get a separate number different from your cell phone number, but then your cell phone number is shared with the BMW eSim and everything goes with your cell phone number.
When I look on my Verizon bill, I see the phone number that has been assigned to the BMW eSIM, but if I call that number nothing happens, everything works as you said with the cell phone number but there is technically a number assigned to the BMW eSIM. What I don’t understand, which people have confirmed, is why when you’re making a call from your cell phone, it doesn’t use the eSIM in the car. In order to use the eSIM in the car, you must use it with voice activation, dial from the screen, or use the contact from the screen. Last edited by Lovin7er; 05-20-2023 at 09:23 AM.. |

We don't know that the esim is not being used for outgoing calls, essentially spoofing the phone number. (Of course nobody from the carriers can tell either). But if in my car I have esim selected as my mobile device, when I make calls they show up on the recipients called id as my cell #. That says to be the esim is being used buy hides the esim number while it shows the phone #. But hey, I really don't know for sure. My big beef with esim is the lack of information on what is really going on

When you activate the eSim, you get a number that is different from your regular number, but you never see it or use it. The technology links your phone to the eSim and everything shows up as your regular number on your phone, even if you use the eSim in your car. That is the nice part of how they did it, and it's the same, as others have pointed out, with your phone and the Apple Watch. I am talking about whether you are using the car's powered antenna to get the improved reception and what everyone has found it is that you must you the eSim to get this powered antenna, and you must use it from voice activation, or the BMW Screen. If you use your phone, it by-passes the eSim and you just are using your phone's antenna. . Last edited by Lovin7er; 05-21-2023 at 04:00 PM.. |

Thanks! I hadn't paid attention. Esim remains very strange in many ways. Still deciding whether I will stay with it.

Forget about the voice for a moment, I have found the Data via Wifi to be very unreliable. When it works, it's very fast, but a lot of times, something has to be reset to make it work. It is not as seamless as it should be.

This is all really good information, since nobody was able to explain to me how the eSIM feature works (or doesn't), so I haven't messed with it yet.
Thanks, all.

On ATT. The data via wifi works for me. I have an Escort detector that uses wifi for updates. It took some digging but I found the car wifi pw and was able to connect, and it seems to work. But I am not watching all the time to see if it drops the signal.
