Why is my LTE stick suddenly deactivated?

Hi! I usually just plug my stick into the laptop and enter my unlock code. Then I also have access to my mobile data. It's been different since yesterday. The stick is constantly deactivated and I can't simply unlock it in the usual way. (Of course I still have enough data.) What is wrong with the stick? Thank you in advance! 🙏

Turn off your Wi-Fi.

I already have it. 😔

Have you got Wi-Fi sticks, did you take him out?

Then get the recommended app

does not work, hook out managed in Windows.

Try everything out
