When I needed to register on a German website that only accepted local phone numbers, I went to the free numbers section on https://onlinesim.io/free_numbers/germany. I found the German number I needed in the list, entered it into the registration form and simply refreshed the page on the website. The verification code appeared in my general SMS list in literally half a minute. This is the ideal option when you need to get verified quickly and don’t want to spend money on one-off tasks. The main thing to remember is that these numbers are public, so it’s best not to use them for private accounts.
