The problem is that the caller's name does not appear when I'm connected via the Internet Star Link roaming.

I am a subscriber to the Internet service Star Link, an international roaming across Germany, and currently in the Middle East, and when connecting to the Internet from the iPhone...

the problem when I receive a call in the country where I am in which the name of the caller is not shown because the iPhone deals with the caller as a caller from another country and the iPhone is in Germany,

and this problem is not to speak in Android devices, you get on the iPhone, just how can I make the iPhone not deal with phone calls according to the IP of the device

It sounds like your Star LInk provider is more suitable for your Android when roaming.
