Can the router be operated with a physical second sim (from Wingo) via my regular mobile plan? According to Wingo, throughput is limited to max. 1 Mbit/s without the optional Full Speed 5G option, but this should be sufficient for my application. I need the router to supply a technical room in an apartment block with WLAN (for connecting Elco heat pumps, water softeners, etc.) for remote reading / maintenance so that I can access it in the event of a fault without having to go there directly. Thank you and best regards
