@enriquericos For future reference: In English, it should be "what" they're called, not "how" they're called.
If you asked someone how they're called, the might answer something like "I don't know? On a phone? How else would you call things?"
I see this error very often on the English Learning subreddits. I'm told that it's a literal translation of other languages, who actually use "how" in this case.
