Netgear Hotspot Nighthawk M1
The thing is explicitly advertised for use when travelling or in hotels (offloading with WiFi or Ethernet from the hotel to save data volume). Most hotels I know use a captive portal where you have to enter your room number/name or something and not just a WiFi with password. Does offloading work if such a captive portal is connected upstream?
