So first of all I am disappointed that there is not even a German description! But now to the problem, I have a wifi connection to the Macbook, SIM card is in the router, also shows 5G in the top left corner, But when I want to call up a website on the Macbook, there is always no internet connection. Do I have to make any other settings ?

How do I get a software update? Supposedly there is none, but a newer version is clearly available on a second router.

Is it normal that the SIM card is only held in place by the cover on the side, i.e. that it does not click into place?

I have not found any information about IPV6 compatibility. No information in BA either. Who knows more? Thanks for your help

Does the ZTE MU5120 router work with SUNRISE Switzerland data tariffs (Sunrise Mobile WiFi)? Please only real experiences with this combination and no speculations!
