So, I drive about 50 miles each way to work. The last part is on the A3(M) towards Portsmouth. Pretty much the entire A3(M) is a black spot for coverage via the eSIM. In the map display, you go from having the Google logo and "ONLINE" in bold, to a greyed out Google logo, and "ONLINE" replaced by "TMC PRO"
At the same point on every journey, presumably after there has been no connectivity for a set period of time, an MMI message pops up to say that there is no connectivity - to which I click "Accept"
Now, this is normally not a huge problem, as it caches the google earth mapping for some way ahead on the journey, but it does mean that you lose traffic info.
So, today, I can see for the first 30 mins of my journey that there is something wrong on the A3(M) as there is a few miles of very slow traffic. I watch the traffic delay build up to about 15 mins, before the Nav told me that the route had been changed. However, I was still going to have to sit in about 0.5 mile of traffic before getting to the junction to leave the A3(M) on.
I duly arrived at the back of the queue and slowed to a crawl, at which point, the mobile coverage dropped out. Because it no longer had any traffic data, it politely told me that the route had changed again, and directed me to continue following the A3(M) in a huge traffic jam, and my arrival time was adjusted to about 10 or 15 mins earlier. I was in the queue for at least a couple of mins, and no data came through via TMC.
Fortunately I still keep my very well trusted TomTom in the glove box and having plugged that in, it confirmed there was still a 15 min delay on the A3(M) and took me off on a diversion route, with the MMI Nav repeatedly trying to get me back on the A3(M) and into the traffic jam for the next 5 mins.
So, a long and not terribly interesting story, but I wonder what carrier they use that has no mobile coverage on about 5 or 6 miles of motorway class road. I had presumed that it used some sort of carrier-flexible SIM technology such as is used in Smart Meters, but obviously not.
I wonder if there is a way to make it so that if there is no eSIM coverage, you can drop back to using the data service from the connected mobile phone.
