I have tried to sign up for my own Netflix account repeatedly over the last three years. For some reason, they don't like my phone number. It's just a regular phone number, on an American SIM card, when I'm solidly (and always) in America. It's the only one I have. But they don't like it, so I can't use Netflix at all unless I sign into someone else's account (with that person's consent), usually my mom, who lives in the next town over but is not in my household, or my brother who lives farther away. I'm only willing to make so many attempts to convince a company to let me give them money before I decide their service isn't worth the hassle.
