Update: It works fine with my Salt router (wireless)

I don't know, but I don't think it works without cables.

I don't know. You'll have to look at the online instructions for use. But beware, it's thicker than the Bible 🤣. I'm sure I could get a lot more out of the phone if I took the time. Still, a stylish and great phone with a lot of pleasant ringtones. .
