Unable to call friend’s eSIM number on iPhone 12 from iPhone 11
I have an iPhone 11. My friend has an iPhone 12 with an extra eSIM with a foreign number. I can call his main number, but cannot get through to his eSIM number (immediate 3 beeps). I can receive his eSIM number. And I can get through to similar foreign numbers - just not his. Other people can get through to his eSIM number.
[He has not blocked me. I have tried restarts, etc.] Any ideas?
