If your passport doesn't allow
But isn't it the purpose of applying for a visa, so that I can travel to Germany? But yes, I plan to send an email to the consulate in the next weeks to ask about that possibility.
Open borders... not much checking...
I'm assuming they do not have valid visa at that time? Do you have link about this story? So I can read what happened. Because I actually have been to Germany for 3 weeks when my national visa is still valid. Went there by train, and returned back by train as well 1 day before my visa expiration.
I was checked once on my way to Germany by Polish border guard. Did not have problem since visa is still valid. I also brought with me my papers (proof of residence card application, work permit, work contract, etc.) just in case - but it was not asked.
your precise natíonality would be?
Filipino, with Philippine passport.
