Nokia 6.1 purchased from India does not support data or voice call in USA after using international roaming also. The same sim works well with other phones.
Maybe this will explain you problem.https://www.worldtimezone.com/gsm.html

I am facing the same issue with roaming within the country (India). Phone is able to connect to the mobile network while roaming but data connectivity fails. It works fine when I am back in my base region.
Seems like a software issue to me.
