Can Netflix be used abroad?

The holidays I will spend outside of Germany and I remembered that I often had problems with German videos on YouTube, so I assume that the videos are also blocked in Netflix.

Is this correct?

because if so I do not need to get it.

Netflix offers its own selection by country. That does not correspond to the German selection. You can't change them.

Locked is nothing, just "not available". And instead of just something else, many series, etc. You will not "starve" cinematically.

Often you can set German subtitles or even German language.
