I live in the US for a year and probably need a new smartphone soon. I still have an iPhone and have recently been very impressed with Huawei since I had the P8 last year and it was perfect for me. Now I would like to buy the Huawei Nova 5T, but can I get this at all or benefit? And what kind of operating system does that have? Still Android?
If you get a sim card from an American provider (which in my experience is cheaper) you can use it more easily there. It is still running on Android. You might get some security updates later.
Android is just the operating system, pay attention to the name quadband. https://www.teltarif.de/roaming/handy-frequenzen.html
GSM 850 and GSM 1900 are common only in the Americas
