Hey!
I have the iPhone 14 Pro for 2 weeks now and am also having problems with connectivity (I am from Germany) Mostly while having bluetooth, mobile data and wifi automatically put on. When changing from a wifi environment to a non wifi environment it takes up to 5-6 minutes to connect to my mobile data. It's SO stupid and annoying. I came from android / an old and very cheap xiaomi (200 € 3,5 years ago) and never experienced such problem.
I am using the same physical sim.
Whenever I am in a wifi enviroment and take wifi off manually it connects INSTANTLY to my mobile data. No problem there - so I assume it has something to do with the automatic connection between those "networks".. when i leave my car with bluetooth connected, it often also disconnects from internet (mobile data , in this case).
So stupid. 1100€ and basic settings are not working. what a disappointment.
@Mhmcv-70: So, same problem here but no VPN installed. Most likely thats not the problem.
Did anyone receive help already?
