I do use the international dual sim version here in USA on T-Mobile.
5G almost never connects, since the version I have does not support the MM wave 5G antenna. So, pretty much stuck on 4G only.
An USB-WIFI adapter might not work, but a USB to ethernet adapter should work, if getting the device internet access is all you want.
