How can I link my existing contacts to my new eSIM number?

Hello! I'm in the US and I just added an e-sim, i got a US phone number but I don't know how it works. Is that a way to syncronize my contacts on the italian number with the new US number? I want to know who is calling if I have that number registered on my phone. Thank you!

Both your eSIM lines will share the same set of contacts, but you can choose which number to use for each contact by labeling them.

Hello Zachyy,
Thank you for your reply. I really appreciate it, but maybe I didn't explain myself properly.
I was asking: when people are calling my US number (e-sim) I don't see their number registered even if they are in my contact list on the other phone number. Should I label them all again or is there a way to just syncronize the contacts?
I hope now it's more clear. Thank you very much!

In that case, I would suggest you contact your carrier as Caller ID a feature of theirs. Contacts should sync but there seems to be issues.
