Let me start by apologizing for writing in English, mein Deutsch ist nicht so gut
So, I know how weird the title sounds. Normally one would expect issues when roaming, but my wife and I are encountering the reverse problem: we can't receive any SMS from outside Austria. I'm attaching a couple of screenshots of what this looks like from the senders perspective.
We ported to Magenta from Spusu recently, and ever since then we just aren't getting any external messages. Messages from within Austria come through just fine, as well as calls from everywhere. Before the number migration everything used to work just fine.
That our family abroad can't message us is not a big deal, there are plenty of other ways for them to get in touch with us, but we've been locked out of important services which use 2FA for authentication, such as Allianz here in Austria, our medical insurance provider (which probably uses an international service for automated SMS).
We opened a support ticket, and Magenta has closed the issue as fixed, even though it clearly hasn't. We've tried restarting the phones (Samsung Galaxy S10 running Android 12) multiple times to no avail, and of course we've confirmed that the correct service center number is set up in both phones.
Anyone ever encountered this issue?
Thanks a lot!
