How can I verify a student portal account with a German phone number?

I was looking for an apartment in Munich for the upcoming semester and found a great listing on the local student portal WG-Gesucht. To contact the owner, I needed to quickly verify my account using a German phone number. I selected an available number from https://onlinesim.io/free_numbers/germany, sent the request, and instantly retrieved the confirmation code. Thanks to this, I was the first to message the landlord and secure a wonderful room.
