How to select ALL contacts in the People App for export?

I want to export ALL my 235 contacts from my simcard to the phone.
Is there a way to select all the contacts in one go or do I have to click on every contact to select them?

Answer from Gert:

When importing/exporting, on the blue top bar on the screen,
tap on “0 selected” and choose “select all”

This question was originally placed on the old forum select all contacts

Addition: sometimes not all the contacts are copied. This can happen if a name contains a diacritical mark.
