So my dad bought this router for his caravan because some guy on Youtube said it's so great and easy to use with some basic knowledge. Unfortunately no matter what I try it won't stay on mobile network, he has a SIM card from Telekom, we entered the PIN in the setup wizard, but it just goes offline all the time. Ethernet works, WLAN works, but Mobile won't. I tried everything I could in the WebUI, I can't figure it out.
I tried for find some reseller in Germany who could help, but didn't find one. We would pay some specialist to figure this out and get it up and running, WLAN if available, LTE if not. Please finde below the troubleshoot file and thanks in advance for your help!
This is what it shows in the logs:
